Answer:
Step-by-step explanation:
for inverse of f(x)=2x+2
x=2y+2
x-2=2y
(x-2)/2=y
therefore the inverse f(x)=(x-2)/2

Answer:
77
Step-by-step explanation:
I did the question and I got it correct.
Answer:
t= 11
Step-by-step explanation:

Gradient of line that contains points (3, 7) & (5, 11)


= 2
The product of the gradients of two perpendicular lines is -1.
Gradient of the line that contains points (t, -2) & (-3, 5)
= -1 ÷2



Cross multiply:
-(t +3)= -7(2)
Dividing by -1 on both sides:
t +3= 7(2)
t +3= 14
t= 14 -3
t= 11
x=-5
