Atriangle has the vertices a(–7, 8), b(1, –7), and c(7, 6). after a dilation, the vertices of the image are a'(–28, 32), b'(4, –28), and c'(28, 24). what is the scale factor of the dilation?

i think it's b

step-by-step explanation:

because the graph is 2 above (0,0)

function 2 has a greater rate of change than function 1

function 2 has a greater y-intercept than function 1

step-by-step explanation:

225x²+4=0

225x²=0-4

225x²=-4

x²=-4/225

x=±√-4/225

answer:   x = 3 + √11     and     x = 3 - √11

step-by-step explanation:

x² - 6x + 9 = 11

(x - 3)² = 11

x - 3 = ±√11

    x = 3 ± √11

x = 3 + √11     and     x = 3 - √11
