The graph of the parent function f(x) = [xis dashed and the graph of the transformed function g(x) = [x - h| is
solid.
Use the slider to change the value of h. How does
changing the value of h affect the vertex?
Positive values of h shift the graph.
Negative values of h shift the graph.

the volume is the product of the area of the base, 3x(3x+4), and the height, 3x-1

step-by-step explanation:

47 - 90 = 43

43 - 180 = x

x = 137

what i would say the best answer is a. 40.5

second option

step-by-step explanation:

the measures of a triangle equal 180. use that to find x.

2x+3x+4x=180

9x=180

9x/9=180/9

x=20

now you know x, you know angle a is 40°, angle b is 60°, angle c is 80°.

because angle a is 40°, the first option doesn't work.

because angle b is 60°, the second option does work.

when you add angle a and b, you get 100°. complementary means it equals 90°, so the third option doesn't work.

when you add angle a and c, you get 120°, which is not 100.
