Center c and a scale factor of 2
zlopas [31]3 years ago
4 0

Answer: C) center C and scale factor 2

Step-by-step explanation:

Since, The center of a dilation is a fixed point in the plane about which all points are expanded or contracted.

Therefore, By the given diagram we can say that the image is dilated along the point C.

⇒ C is the center of the dilation.

Since, for the given diagram the scale factor of dilation = \frac{C'A'}{CA} = \frac{10}{5} = 2

Thus, the scale factor is 2.

Therefore, Option C is correct.

How do you solve f (x)=-3 (x+2)+2
Allushta [10]

Answer:

−1/3y+−4/3

Step-by-step explanation:

We need to solve for x.

How? Easy! :D

Step one: Flip the equation. (In class we call it the 'flip-flop'.) When you do this, you should have your equation look like this:

−3x−4=y

Step two: Add 4 to both sides of the equation. When you do this step, your problem should look like this:

−3x−4+4=y+4

−3x=y+4

Step three: Divide both sides by -3.

-3x/-3 = y+4/-3.

Step four: Wrap-up. What the answer is.

x = -1/3y + -4/3

Final step: OUR ANSWER!

x = -1/3 + -4/3

Hope this helped! :D
