(0,-2) (4,-1) which equation represents the graphed function?

Conclusion:

Working backward will create an equation, but remember that there are other equations that will also have that same set of solutions.

(Compare the solutions in 1a with 1b, and take a look at the graph at the right.)

Any equation of the form k(x2 + x - 12) = 0, where k is a constant, has the same solutions as  x2 + x - 12 = 0.

this is answer of 144 cubic meters

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.
