Answer

40% = 0,4

Divide 40 by 100

remove the 0s from both side

it will be

4 ÷ 10=

you go one step to the right and add a zero before the dot

which equal to

Step-by-step explanation:

X-AXIS

when a graph intersects the x-axis, the y value is always 0.  

Ex.  Points (1,0), (-5,0), (-3,0), (6,0), etc. are all on the x-axis because y = 0.  

to find where the graph crosses the x-axis, let y or g(x) = 0

0 = -5^x + 5  subtract 5 from both sides

-5 = -5^x       if x is 1, that would produce -5 = -5

(1,0) x axis

Y-AXIS

when a graph intersects the y-axis, the x value is always 0.

Ex.  Points (0, 1), (0, -2), (0, 3), etc. all lie on the y-axis because x = 0.

to find where teh graph crosses the y-axis, let x = 0

does the exponent "x" apply to (-5) or just 5?  

[tex]-5^{x} or (-5)^{x}[/tex]

(-5)^0 + 5    any number with a 0 power is 1

1 + 5 = 6

(0, 6)

or -5^0 + 5

       -1  +  5 = 4

(0, 4)

Answer:

itsc c (0,3) ,d(3,0)

Step-by-step explanation:

If AB is divided into three equal parts then coordinates of C is  (0, 3) and D coordinates are (3, 0)

A system that uses one or more numbers, or coordinates, to uniquely determine the position of the points or other geometric elements on a manifold such as Euclidean space.

Divide AB into three equal parts

[tex]X_{c}-X_{a}=\frac{1}{3} (X_{B}-X_{D})[/tex]

=3

[tex]Y_{a}-Y_{c}=\frac{1}{3} (Y_{A}-Y_{B})[/tex]

=3

So C is (0, 3)

[tex]X_{B} -X_{D} =\frac{1}{3} \times 9[/tex]

=3

[tex]Y_{D} -Y_{B} =\frac{1}{3} \times 9[/tex]

=3

So D coordinates are (3, 0)

Hence, if AB is divided into three equal parts then coordinates of C is  (0, 3) and D coordinates are (3, 0)

Answer:

True

Step-by-step explanation:

The points (2,3) and (2,-6) are undefinable because it makes a vertical line. The slope cannot be defined.

Answer:There are zero interception.

Step-by-step explanation:

The equation to Line U: is  y=-3x +19  and the equation to line V  is  y=-3x +14

So as you can see ,the lines have the same slopes but different y-intercepts.This means the lines are going to be parallel when being graph.Parallel lines never cross or intersect so there  is no points of intersection.

A. zero.

Answer:

The y-intercept of function g located at (0,2)

Step-by-step explanation:

Function :[tex]g(x)=x^2+2[/tex]

g(x) is a transformation of the quadratic parent function

We are supposed to find the where is the y-intercept of function g located

y intercept = the y-coordinate of a point where a line, curve, or surface intersects the y-axis i.e. x =0

So, substitute x = 0 in function

g(x)=x^2+2

g(0)=0^2+2

g(0)=2

So,(x,y)=(0,2)

So, The y-intercept of function g located at (0,2)

Explanation:

Choices C and D are in slope intercept form, and not standard form, so we can rule them out. It's been choice A and choice B.

Solve for y in choice A, and you should get y = (1/4)x-1. The slope is 1/4. The positive slope tells us the line moves uphill as you move from left to right. In contrast, x+4y = 4 has a negative slope because it solves to y = (-1/4)x+1. Therefore, choice B can be eliminated.

To confirm that choice A is the correct answer, plug in each point and see if we get a true equation. Let's start with (0,-1)

Plug in (x,y) = (0,-1)

x-4y = 4

0-4(-1) = 4 ...  replace x with 0, replace y with -1

0+4 = 4

4 = 4 ... true equation, so the point (0,-1) works

Now try the other point

x-4y = 4

4-4(0) = 4 .... plug in (x,y) = (4,0)

4-0 = 4

4 = 4 ... works as well

Both points make the equation true, so they are both on the same line.

at the vertex between the green and blue vectors

Step-by-step explanation:

Answer:

y= ¾x +6

Step-by-step explanation:

The equation of a line is usually written in the form of y=mx+c, where m is the gradient and c is the y-intercept.

Let's find the gradient first.

[tex]gradient = \frac{y1 - y2}{x1 - x2} [/tex]

Using the formula above,

[tex]m = \frac{6 - 3}{0 - ( - 4)} \\ m = \frac{3}{4} [/tex]

subst. the value of m into the equation.

[tex]y = \frac{3}{4} x + c[/tex]

To find c, substitute a coordinate.

When x=0, y=6,

[tex]6 = \frac{3}{4} (0) + c \\ 6 = 0 + c \\ c = 6[/tex]

Thus, the equation of the line is [tex]y = \frac{3}{4} x + 6[/tex].

Answer:

Step-by-step explanation:

x = 36.67 or 36 and 2/3

Answer:

a=1, b= 7, c=0

Opens upward since a is positive(meaning it has a minimum vertex)

Y-int: (0,0)

Step-by-step explanation:

y=[tex]x^{2}[/tex]+7x

In order to find, the y-intercept, x has to be 0, so plug in 0 for x

y=[tex]0^{2}[/tex]+7(0)

y=0

So the y intercept: (0,0)

The equation form a parabola that opens up and the y intercept is at y = 0. a = 1, b = 7 and c = 0

A quadratic function is in the form:

y = ax² + bx + c

Given that:

y = x² + 7x, hence:

a = 1, b = 7 and c = 0

The equation form a parabola that opens up and the y intercept is at y = 0.

Answer:

The solution set for [tex]s<3[/tex] would be (-∞,3)

The solution set for [tex]|s|<3[/tex] would be (-3,3)

Step-by-step explanation:

The solution set for [tex]s<3[/tex] can be any number that is lower than 3.

When we have the inequality  [tex]|s|<3[/tex], we need to rewrite this without the absolute values to find our answer

[tex]|s|<3[/tex]

[tex]s<[/tex] ± [tex]3[/tex]

This can be be split into [tex]s<3, s<-3[/tex]

But, there one thing that needs to be done to the inequality with the-3. As we multiplied it by a -1 to make it negative, we must reverse the sign of the inequality. This leaves us with [tex]s<3, s>-3[/tex]

Now, we can combine these to get one inequality

Answer:

False

Step-by-step explanation:

In order for the dilated image to become larger, it has to have a scale factor that is more than one not less than one.

False, Because If the scale factor is greater than 1, the image is larger than the preimage.

Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.

We know that;

If the scale factor is between 0 and 1, the image is smaller than the preimage. Dilations with a scale factor between 0 and 1 are called reductions.

And, If the scale factor is greater than 1, the image is larger than the preimage. Dilations with a scale factor greater than 1 are called enlargements.

Thus, The given statement is false.
