Answer:
3/7 x +5=8
move 5 to the other side
3/7 x= 8-5
3/7 x= 3
then move 7 to the other side it's sign is ÷ it will be ×
then 3x=3×7
3x=21
then move 3to the other side it's sign is × it will become ÷
x= 21/3
x= 7
Answer:
x=7
Step-by-step explanation:
y = x2 − 4
Answer:
The inverse of f(x) is
y = x² - 4
x = y ² - 4
y² = x + 4
y = √x + 4
The inverse of the function is y = √x +4
Hope this helps.
