NEED HELP WITH BOTH PARTS URGENTLY‼... FIND THE COORDINATES OF THE POINT WHERE y-4x=1 crosses the y-axis
THE DIAGRAM SHOWS THE GRAPH OF Y = 2x + c , where c is constant.
a) (0, 1)
The graph will cross the y-axis at the y-intercept. We can easily find this value by putting the given equation into slope-intercept form (y = mx + b).
y - 4x = 1
y = 4x + 1
The y-intercept is (0,1).
b) k = 6.5
We first need to find c, or the y-intercept. This is given to us on the graph, where the line crosses the y-axis at (0,-3).
Therefore, our line is y = 2x - 3.
Then, we can plug in 10 for y from the point (k,10) and solve for k (which is the same as x).
10 = 2x - 3
13 = 2x
x = 6.5
Hope this helps!
write an equation
of the line in slope - Intercept form
(8,3) (0,-5)
Answer:
y=x-5
Step-by-step explanation:
Hi there!
We want to write an equation of the line that passes through the points (8,3) and (0,-5) in slope-intercept form
Slope-intercept form is given as y=mx+b, where m is the slope, and b is the y intercept
So let's first find the slope of the line
The formula for the slope calculated from two points is [tex]\frac{y_2-y_1}{x_2-x_1}[/tex], where [tex](x_1, y_1)[/tex] and [tex](x_2, y_2)[/tex] are points
We have everything needed to find the slope, but let's label the values of the points to avoid any confusion
[tex]x_1=8\\y_1=3\\x_2=0\\y_2=-5[/tex]
Now substitute into the formula
m=[tex]\frac{y_2-y_1}{x_2-x_1}[/tex]
m=[tex]\frac{-5-3}{0-8}[/tex]
Subtract
m=[tex]\frac{-8}{-8}[/tex]
Simplify
m=1
The slope is 1
Here is the equation of the line so far:
y=1x+b (can also be written as y=x+b)
We need to find b
The equation passes through both (8, 3) and (0, -5), so we can substitute the values of either one of them as x and y to solve for b
Let's take (8, 3) for example
Substitute 8 as x and 3 as y
3=1(8)+b
Multiply
3=8+b
Subtract 8 from both sides
-5=b
Substitute -5 as b into the equation
y=x-5
Hope this helps!
. Given that O is the centre of the following circle, find the values of the unknowns.
Given:
Radius of circle is 13 cm
Height of triangle is 5 cm
To find:
Value of 'a' and 'b'
Steps:
To find value of 'a', we will use Pythagoras theorem as the triangle is a right angle triangle,
A² + B² = C²
[tex]a^{2} + 5^{2} = 13^{2}[/tex]
[tex]a^{2} + 25 = 169[/tex]
[tex]a^{2} = 169 - 25[/tex]
[tex]a^{2} = 144[/tex]
[tex]\sqrt{a^{2}}=\sqrt{144}[/tex]
[tex]a = 12[/tex]
Now to find the value of 'b', i will use law of cosine,
[tex]c=\sqrt{a^{2}+b^{2}-2ab(cos\beta ) }[/tex]
[tex]12 = \sqrt{13^{2}+5^{2}-2(5)(13)(cos\beta )}\\12=\sqrt{169 + 25-130(cos\beta )}\\12=\sqrt{194-130(cos\beta )}\\144 = 194 - 130(cos\beta )\\50 = 130(cos\beta )\\cos\beta = 0.3846\\\beta = cos^{-1}(0.3846)\\\beta = 67.38[/tex]
Therefore, the values of 'a' and 'b' is 12 and 67.38 respectively

A line plot with the lengths of meteors is shown. Two more identical meteor measurements were added so that the total length of all meteors measured is 16 inches. What is the length of each new meteor?
A line plot with the title, length of meteors. The data is measurement in inches. The line plot goes from two eighths to one and seven eighths, with fourteen tick marks in all. The first tick mark is two eighths and has one data point. The second tick mark is three eighths and has three data points. The third tick mark is four eighths and has two data points. The fourth tick mark is five eighths and has no data points. The fifth tick mark is six eighths and has two data points. The sixth tick mark is seven eighths and has no data points. The seventh tick mark is one and has no data points. The eighth tick mark is one and one eighth and has no data points. The ninth tick mark is one and two eighths and has one data point. The tenth tick mark is one and three eighths and has two data points. The eleventh tick mark is one and four eighths and has no data points. The twelfth tick mark is one and five eighths and has no data points. The thirteenth tick mark is one and six eighths and has two data points. The fourteenth tick mark is one and seven eighths and has one data point.
1 inch
one and one eighth inches
one and two eighths inches
one and three eighths inches
Answer:The answer is 1 3/8 (D)
Step-by-step explanation:
If you added the amounts of each tick mark (which would be 13 2/8), and then subtracted it by 16, it would be 2 6/8. 2 6/8 divided by two (because we need to find the length of both of the indentical meteors) would be 1 3/8.
Now, to make sure it is 1 3/8: 13 2/8 + 1 3/8 + 1 3/8 = 16.
It is confirmed, 1 3/8 (Answer D) is the correct answer.

Select the reason that best supports statement 5 in the given proof help pls
Answer:
A
Step-by-step explanation:
Subustion works because we already know two things are congruent so we just "substitute the angles into for the variables.
We know Angle A equal Angle B so we can replace angle A into m of Angle B and set it equal to Angle B variables.
We dont do know algebra operation to solve for the variable so we B and C aren't the option.
We already know two things are equal so we dont need to use transitive.
The reason that best supports statement 5 in the given proof is option A. Substitution.
What is Substitution:The process of substituting an algebraic letter for its value is known as substitution.
Take the equation 8 - 4x as an example. Depending on what number x is, this can take a wide range of values. For example, if we are told x = 3 then we can substitute 3 in place of x.
Multiplication property of equality:Let's take an example,
x ÷ 2 = (5x - 54)
x ÷ 2 × 2 = 2 × (5x - 54)
x = 10x - 108
then by multiplication property of equality, we can multiply 2 on both sides and rewrite the equation,
x = 10x - 108
Addition property of equality:Let's take another example,
x - 2 = 2
then by addition property of equality, we can add 2 on both sides and rewrite the equation,
x - 2 + 2 = 2 + 2
x = 4
Transitive property:In math, if A=B and B=C, then A=C
For example, if A is 5 then by the transitive property we can conclude that B and C are also equal to 5.
What is congruency?Two geometric figures are said to be congruent or to be in a congruence relation if they can be superposed on top of each other and remain the same throughout.
In the given question -
The first reason is given in the question itself.The second reason is given by congruency.The third reason is again given in the question.The fourth reason is also given.Finally, in the fifth reason, we can conclude that it is substitution because by the second reason m of ∠A is congruent to m of ∠B. So, if we remember the substitution we can assign the value of m∠A to the value of m∠B because both are congruent by the second reason.
Therefore, the reason that best supports statement 5 in the given proof is Substitution.

6x = 12 ( divide both sides by 6 )
x = 2
Answer:
[tex]x=2[/tex]
Step-by-step explanation:
The term 'secant' refers to a line segment that intersects a circle in two places. When two secants intersect inside a circle, one can use the product of lengths theory to form ratios between the parts of intersection between the secants. This ratio can be described as the following, let ([tex]secant_A[/tex]) and ([tex]secant_B[/tex]) represent the two secants in the circle. Part (1) and (2) will refer to the two parts formed after the intersection of the secants.
[tex](secant_A_1)(secant_A_2)=(secant_B_1)(secant_B_2)[/tex]
Use this formula in the given situation, substitute the given values in and solve for the unknown,
[tex](secant_A_1)(secant_A_2)=(secant_B_1)(secant_B_2)[/tex]
[tex](6)(x+2)=(12)(x)[/tex]
Simplify,
[tex](6)(x+2)=(12)(x)[/tex]
[tex]6x+12=12x[/tex]
[tex]12=6x[/tex]
[tex]x=2[/tex]
Can you answer this math homework? Please!
Answer: (3.5,-2)
Step-by-step explanation:
To solve this problem, all we have to do is plug in y=-2 into either equations from step one to find the coordinate. To make sure we have the right x-coordinate, let's plug in y for both equations.
4x-7y=28 [plug in y=-2]
4x-7(-2)=28 [multiply]
4x+14=28 [subtract both sides by 14]
4x=14 [divide both sides by 4]
x=3.5
------------------------------------------------------------------------------------------------------------
6x-5y=31 [plug in y=-2]
6x-5(-2)=31 [multiply]
6x+10=31 [subtract both sides by 10]
6x=21 [divide both sides by 6]
x=3.5
Now, we know the solution to the system is (3.5,-2).
Answer:
(3.5, -2)
Step-by-step explanation:
Hi there!
We are given a system of equations, and the value for y is already solved (y=-2)
We want to find the value of x
To do that, substitute -2 as y into either one of the equations in the system (the system has the equations 4x-7y=28 and 6x-5y=31) and solve for x
Let's use 4x-7y=28, although picking 6x-5y=31 is completely fine
Substitute -2 as y into the equation
4x-7(-2)=28
Multiply
4x+14=28
Subtract 14 from both sides
4x=14
Divide both sides by 4 and simplify
x=7/2, or 3.5
We found the value of x in the system
Substitute the values of x and y into a point form (x, y)
The solution is (3.5, -2)

A triangle is a polygon with three sides and three angles. Types of triangles are isosceles. scalene, equilateral, acute, obtuse and right angled triangle.
A right angled triangle is a triangle in which one of the angles is 90 degrees. Trigonometric ratios show the relationship between the angles of a right angle triangle and its sides.
Let h represent the height of the house above water, hence using trigonometric ratios:
tan(26) = h / 531
h = 531 * tan(26)
h = 259 ft.

Step-by-step explanation:
rrrrrrrrrrrrrrr
The equation for the scenario is x + x+1 + x+2 = 117 and largest number is 40.
What is a linear equation?It is defined as the relation between two variables, if we plot the graph of the linear equation we will get a straight line.
If in the linear equation, one variable is present, then the equation is known as the linear equation in one variable.
Let x be the first number:
The other numbers are:
x+1, x+2
The sum of three consecutive numbers is 117:
x + x+1 + x+2 = 117
3x + 3 = 117
3x = 114
x = 38
x+ 1 = 38+1 = 39
x+2 = 38+2 = 40
Thus, the equation for the scenario is x + x+1 + x+2 = 117 and largest number is 40.

Answer: Choice B
[tex]\text{As } x \to \infty, \ f(x) \to \infty[/tex] and [tex]\text{As } x \to -\infty, \ f(x) \to \infty[/tex]
==========================================================
Explanation:
Assuming that the only roots are x = -3 and x = 2, as shown by the table, then notice how f(x) > 0 at the very right hand side of the table. This indicates that f(x) will remain positive for this tail end. If f(x) were to become negative, then there would have to be another root somewhere beyond x = 2 (but that contradicts the assumption made at the top of the paragraph).
This allows us to say [tex]\text{As } x \to \infty, \ f(x) \to \infty[/tex]
In other words, as x gets bigger, so does y. Both head to positive infinity together. We can informally describe this end behavior as "rises to the right".
----------------------
For the left side of the table, we also have positive f(x) values to the left of the root. So we see that f(x) > 0 as x heads off in the negative infinity direction.
We would then say [tex]\text{As } x \to -\infty, \ f(x) \to \infty[/tex]
Regardless of what direction x goes (positive or negative infinity), the y = f(x) values are heading off to positive infinity. Informally, we could say "rises to the left".
Both endpoints rise together to positive infinity. Think of a parabolic curve that opens upward as one example.
All of this points to choice B as our final answer. Choice B can be rephrased as [tex]\text{As } x \to \infty \text{ or } x \to -\infty, \text{ then } \ f(x) \to \infty[/tex]
