Describe each transformation. Then write the equation of the transformed function. f(x) = 2x + 1
a. f(x) - 5
b. f(x – 5)

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
