If f(x) = 1/x+1 and g(x) = x^2, what does f(g(-1)) equal?
a. -1
b. -1/2
c. 0
d. 1/2
e. 1

D: f(g(-1)) = 1/2

Step-by-step explanation:

f(x) = 1/(x + 1)

g(x) = x²

g(-1) = 1

f(g(-1)) = 1/(1 + 1)

f(g(-1)) = 1/2

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
