Triangle FGH has vertices F(−5, 0), G(0, 5), and H(5, 0). A dilation, centered at the origin, is applied to this triangle. The image has vertices F′(−30, 0), G′(0, 30), and H′(30, 0). What is the scale factor of this dilation?

step-by-step explanation:

step 1: solve one of the equations for one of the variables. let's solve the first equation for y:

step 2: substitute that equation into the other equation, and solve for x.

step 3: substitute x = 4 x = 4 x=4 into one of the original equations, and solve for y.

m∠a is 90°

m∠b is 40°

c) the median for town a 30" is greater than the median for town b 25"

step-by-step explanation:

town a, median = q2 = 30

town b, median - q2 = 25

so the median for town a 30" is greater than the median for town b 25"
