Answer:
The inverse is (x) =
Step-by-step explanation:
(By the way, (x) is f negative one of x, like f(x), but inverse)
f(x) = - 4 is the same as y =
- 4
y = - 4 start with the equation.
x = - 4 switch x and y.
x + 4 = add 4 to both sides.
= y square both sides.
(x) =
change y to the inverse f(x) format.
I hope this helps! :)
Answer:
x = 10
Step-by-step explanation:
Given
+ 13 =
( multiply through by 10, the LCM of 5 and 2 to clear the fractions )
2x + 130 = 15x ( subtract 2x from both sides )
130 = 13x ( divide both sides by 13 )
10 = x
