A triangle is dilated with a center of dilation at the origin. Point P is on the figure and P' is the corresponding point on the
image of the dilation. Point P is at (-2, 3) and P' is at (-8, 12). Which rule best represents the dilation? *

Answer:
Step-by-step explanation:
<u>Dilation is applied by the rule:</u>
- (x, y) → (kx, ky), where k is the scale factor
<u>We have</u>
- (x, y) = (-2, 3) and (kx, ky) = (-8, 12)
<u>Substitute and solve for k</u>
- -8 = -2k and 12 = 3k ⇒ k = 4
<u>So the rule is</u>

Answer: 2a^5+5b
Step-by-step explanation:
This is actually pretty simple
The exponent with the same power can be subtracted so
4a^5-2a^5 is 2a^5 like 4x-2x which is equal to 2x
4b+b is equal to 5b
2a^5+5b is your answer
