Answer:
The slope is 4 and the y intercept is -5/2
Step-by-step explanation:
8x-2y = 5
Solve for y to get the equation in slope intercept form
Subtract 8x from each side
8x-8x-2y =-8x+ 5
-2y = -8x+5
Divide by -2
-2y/-2 = -8x/-2 + 5/-2
y = 4x -5/2
This is in slope intercept form y= mx+b where m is the slope and b is the y intercept
The slope is 4 and the y intercept is -5/2
Find the gradient of the line y= -4x + 5
Answer:
m = -4
Step-by-step explanation:
The given y= -4x + 5 exactly matches the format of the slope-intercept equation y = mx + b.
Thus, the gradient (slope) of the given line is -4.
In the graph above, what's the distance between (0, 2) and (5, 2)? Question 16 options: A) 2 units B) 5 units C) –5 units D) 4 units
Answer:
B) 5 units
Step-by-step explanation:
The distance between these points (0, 2) and (5, 2) will be 5 units. Then the correct option is B.
What is the distance between two points?It is the measure of distance between the two points and is known as length. The length is measured in meters generally.
Let one point be (x, y) and another point be (h, k).
Then the distance between the points will be
D² = (x - h)² + (y - k)²
The two pints are given below.
(0, 2) and (5, 2)
Then the distance between these points (0, 2) and (5, 2) will be given as,
D² = (5 - 0)² + (2 - 2)²
D² = 5²
D = 5 units
The distance between these points (0, 2) and (5, 2) will be 5 units. Then the correct option is B.

8. Find the area of the regular polygon.
Answer:
To find the area of a regular hexagon, or any regular polygon, we use the formula that says Area = one-half the product of the apothem and perimeter. As shown below, this means that we must find the perimeter (distance all the way around the hexagon) and the measure of the apothem using right triangles and trigonometry. Area of a Hexagon

Answer:

Step-by-step explanation:
The excluded values are the values of x that satisfy [tex]2x^{2} + 14x + 12 = 0[/tex]
Let us solve the equation [tex]2x^{2} + 14x + 12 = 0[/tex]
It's a quadratic equation
Thus, let us calculate the discriminant Δ
Δ [tex]= 14^{2} - 4 .2.12 = 100[/tex]
the discriminant is greater than 0, so the equation has two solutions
[tex]x = \frac{-14 - 10}{4} = \frac{-24}{4} = -6[/tex] or [tex]x = \frac{-14+10}{4} = \frac{-4}{4} = -1[/tex]

The perimeter of a rectangle is 84 cm. If the length is 29 cm write an equation you can use to answer this question
Answer:
Width = 13
Equation: 2 × 29 + 2W = 84
Step-by-step explanation:
Ace here!
I'm going to assume that we have to find the width. In a rectangle, there are 4 sides and opposite sides are congruent.
Let L represent the length and W represent the width.
Since there are 4 sides, we know that to find the of a rectangle perimeter, we have to do:
L+L+W+W=Perimeter
Let's first simplify this equation by combining like terms:
2L+2W = Perimeter
Now, let's plug in known values:
2(29) + 2W = 84
Divide everything by 2:
29+W=42
Isolate W:
W=42-29
W=13
Keep in mind, I didn't have to divide by 2 at the step that I had. I could've also done this:
2(29) + 2W = 84
Simplify:
58+2W=84
Bring everything to one side:
2W=26
Isolate W by dividing 2:
W=13
Two different slightly approaches, same answer.

Answer:
h (x) = 5
h (x) = 2x + 1
h (x) = 2 x 2 + 1 = 5
x = 2
Answer:
x = 2
Step-by-step explanation:
Its given that h(x) = 2x + 1
But its also given that h(x) = 5
[tex]=> h(x) = 2x + 1 = 5[/tex]

Which of the following pairs of functions are inverses of each other?
Answer:
do you have a picture or something So I can answer your question?
Step-by-step explanation:
Option-A is accurate because f(x) = 9(x/2)-8 and g(x) = 2(x+8)/9 are the values we get when solving the function.
What is inverse function?A function receives values, performs certain operations on them, and outputs a result. After acting and concurring with the result, the inverse function switches back to the original function.
The inverse function, which also returns the initial value, returns the result of a function.
this selection. Option-A is the proper choice, so
f(x)=9(x/2)-8
consider the f(x)=y
y=9(x/2)-8
y+8=9(x/2)
(y+8)/9=x/2
2(y+8)/9=x
g(x)=2(x+8)/9
As a result, Option-A, which states that when the function is solved, the output is the inverse function, is correct. Its values are f(x) = 9(x/2)-8 and g(x) = 2(x+8)/9.

Step-by-step explanation:
We will take 2 coordinates from the graph and Find the equation of the line.
Let the coordinates be : ( 0, 1) and (1, 3)
step 1 : find slope
[tex]slope , m = \frac{y_2 - y_ 1}{x_2 - x_1} = \frac{3-1}{1-0} = 2[/tex]
Step 2 : equation of the line :
[tex]( y - y_1) = m (x- x_1)[/tex]
[tex](y -1) = 2 ( x -0)\\y - 1 = 2x \\y = 2x + 1[/tex]
Therefore, y = 2x + 1 represent the equation of the line.
Answer:
C
Step-by-step explanation:
You need to solve for y = mx + b
You can solve for b right away. It is clear that the line crosses the y axis at (0,1) so you have
y = mx + 1 so far.
Normally you would need two clear points to solve for m, but since you know the y intercept, you need only 1 point.
The clearest point I can see is (-2,-3) which means that
x = -2
y = - 3
Put that into the equation and solve for m.
-3 = m(-2) + 1 Subtract 1 from both sides
-3-1 = m(-2) Combine
-4 = -2 m Divide both sides by - 2
-4/-2 = m
m = 2
Answer
only a and c are real choices. That's because m = 2 in both cases.
The equation we got is y = 2x + 1 which is c
Jackie bought an iphone for $200. Find the total
cost including a 7% sales tax,
Find 7% of 200
7% = 7/100
Divide 7 by 100
7/100
= 7 ÷ 100
= 0.07
Multiply 0.07 to 200
0.07 × 200
= 14
Add 14 to 200
200 + 14
= 214
Therefore, the total cost of the iphone including sales tax is $ 214

Bruv take all my points I literally blow at math :'(
Answer:
[tex]b=\frac{4c-a^{2} }{3}[/tex]
Step-by-step explanation:
First: multiply both sides by 4. 4 times c is 4c and the other sides cancels out as you are doing the inverse operation of division
Then, you have [tex]4c=a^{2} +3b[/tex]
Subtract both sides by a squared
DO NOT TAKE THE SQUARE ROOT! This is because it is a squared plus 3b so you have to do the inverse of addition
From that you get [tex]4c-a^{2} =3b[/tex]
Finally, divide both sides by 3.
You get [tex]b=\frac{4c-a^{2} }{3}[/tex]

The circle has 360°.
This can be written as,
Area = πr² x 360/360

The area of the not-shaded part has (360 - 60)°
So,
Area = πr² x 300/360
Now,
r = 12 units
Area = π x 12 x 12 x 300/360
Area = 120π units²
