The graph of the line has an equation of y = 5x - 8. what is the equation of the line after a dilation with a scale factor of 3 2 , centered at the origin. a) y = 5x - 6 b) y = 5x - 12 c) y = 15 2 x - 8 d) y = 15 2 x - 12

B) y = 5x -12

Step-by-step explanation:

Dilation changes the distance of points from the origin, but does not change angles (slopes of lines). Hence the y-intercept moves from -8 to 3/2·(-8) = -12, but the slope stays the same.

0.32

first, you divide the triangle in two, tô form a retangle triangle. after, using pythagoream theorem:

18^2 = 14^2 + (x/2)^2

(x^2/4) + 196 = 324

x^2/4 = 324 - 196

x^2/4 = 128

x^2 = 512

x = √512

x = √2^9

x = 16√2 cm

i hope i you.
