Answer:
a)
Step-by-step explanation:
To find inverse:
replace f(x) with y: y = 2(x + 4)
Then switch y and x: x = 2(y + 4)
Finally make y the subject:
x = 2(y + 4)
x/2 = y + 4 (divide by 2)
x/2 - 4 = y (subtract 4)
So, the inverse is y = x/2 - 4
Answer:
You would subtract 6 from each side.
Step-by-step explanation:
- 14 = 7x + 6
Subtract 6 from each side:
- 14 - 6 = 7x + 6 - 6
7x = - 20
Divide each side by 7:
7x ÷ 7 = - 20 ÷ 7
x = 2 and 6/7
