Function machine
what is f(-10)=
for what input is the output 93

a) replace x with -10 and solve:

-6(-10)-3 = 60-3 = 57

f(-10) = 57

b) replace f(x) with 93 and solve for x:

93 = -6x-3

Add 3 to each side:

96 = -6x

Divide each side by -6:

x = -16

The input value is -16

- (2, -7)

- lines r and s and lines t and u must be parallel
