What will be the y - coordinate of B’ if AB is dilated by a factor of, centered at the origin?

4/5 (choice B)

Reason:

B is located at (10,2)

Multiply each coordinate by the scale factor 2/5

This trick only works if the center of dilation is the origin.

15

step-by-step explanation:

we are given the following expression and we are to solve it and find the product:

-13 × (-5)

solving the given expression in the standard order of solving a mathematical expression, beginning with the opening of brackets and then multiplying the terms and changing their signs.

-3 × -5 = 15 (answer is positive because when negative is multiplied with negative, it gives a positive answer)
