Answer: x=5, choice D
Step-by-step explanation:
you have two vertical angles
11x=55
55/11=5
x=5
Y= -3/4x - 5
slope intercept form is y=mx + b
the mx is your slope, in this equation -3/4
the b is the y intercept, where the line first crosses the y axis. in this equation -5.
hope this helps :)
When x =2, f(x) = 128
When x = 4, f(x) = 8
