ABC was dilated to create A' B' C'. What is the center of dilation? And what is the scale factor of the dilation?
Virty [35]

Given:

In the given figure the vertices of triangle ABC are A(-2,2), B(4,2), C(-2,-2).

The vertices of triangle A'B'C' are A'(-4,4), B'(8,4), C'(-4,-4).

To find:

The center of dilation and the scale factor.

Solution:

In the given graph, draw the lines AA', BB' and CC'. The intersection point of these lines is the center of dilation.

From the below graph, it is clear that the lines AA', BB' and CC' intersect each other at (0,0).

Therefore, the center of dilation is (0,0).

If a figure is dilated by factor k and the center of dilation is origin, then

(x,y)\to (kx,ky)

A(-2,2)\to A'(k(-2),k(2))

A(-2,2)\to A'(-2k,2k)

It is given that A'(-4,4). So,

(-2k,2k)=(-4,4)

On comparing both sides, we get

-2k=-4

2k=4

k=\dfrac{4}{2}

k=2

Therefore, the scale factor is 2.

3x+10y=13<br> 4(-2y+x)-9x=13
mart [117]

Answer:

x=-9

y=4

Step-by-step explanation:

3x+10y=13 ← Equation 1

4(-2y+x)-9x=13\\

By simplifying the above equation we get,

-8y+=4x-9x=13 (Simplifying the brackets)

-8y-5x=13 (By subtracting -9x from +4x) ← Equation 2

Multiply Equation 1 by 5 and Equation 2 by 3 and add them together.

Equation 1 multiplied by 5 will give,

15x+50y=65

Equation 2 multiplied by 3 will give,

-24y-15x=39

Add those together,

15x+50y-24y-15x=65+39

26y=104 (After simplifying x values)

Therefor y=4

By substituting y=4 to Equation 1 we get,

3x+10*4=133x+40=13\\3x=-27\\x=-9

Therefor we can say,

x=-9

y=4

Which table represents a linear functionWhich table represents a linear function
IceJOKER [234]

The table that has a constant average rate of change represents a linear function.

<h3>What is the average rate of change of a function?</h3>

The average rate of change of a function is given by the <u>change in the output of the function divided by the change in the input</u>.

When this rate is constant, the function is said to be linear, hence the table that has a constant average rate of change represents a linear function.
