Given f(x) = -3x + 3, solve for x when f(x) = 9.

x = -2

Step-by-step explanation:

f(x) = -3x + 3

f(x) = 9

-3x + 3 = 9

Subtract 3 from both sides;

-3x = 6

Divide both sides by -3

x = -2

the sum of all the angles in a triangle are equal to 180

so you can add   the 3 given angles together to equal 180:

5y + 2y + 2y = 180

or since all three angles have the same letter, combine the 3 angles to equal 180:

9y = 180

30
