If the following triangle is dilated by a scale factor of 2 about point p, what is the dilated point a'?

(-6,4)
(0,-6)
(-6,0)
(-4,0)

(-6,0)

Step-by-step explanation:

Let the coordinate of dilated point A' be (a,b).

Then the relationship between the scale factor, the center of dilation and the the point of dilation and the dilated point is:

A'+P=2A

We substitute the point:

This implies that:

This implies that:

Therefore A' has coordinates (-6,0)

answer: bea's uncle is 25 years old.

step-by-step explanation:

given the equation , we can say that the variable "x" represents the age of bea's uncle. then to find his age, we need to solve for "x":

we must add 15 to both sides of the equation:

now we need to divide both sides of the equation by 3:

therefore, we can conclude that bea's uncle is 25 years old.
