If f(x)=1/9 x-2,what is f-1(x)?

MAVERICK [17]

Answer:

f^-1(x) = 9x+18

Step-by-step explanation:

To get the inverse of a function, we exchange x and y then solve for y

y = 1/9x -2

Exchange x and y

x = 1/9y -2

Add 2 to each side

x+2 = 1/9y-2+2

x+2 = 1/9y

Multiply by 9

9(x+2) = 9*1/9y

9x+18 = y

f^-1(x) = 9x+18

Katie's gross monthly salary is $3,800. 22% of her income is set aside for income taxes. Katie saves 8% of her salary. after tax

padilas [110]

Katie has $2726.88 to spend each month after taxes and savings

Step-by-step explanation:

The information about Katie's monthly salary is:

1. The gross monthly salary is $3800

2. The income taxes is 22% of her income

3. She saves 8% of her salary

We need to find how much Katie has to spend each month after taxes

and savings

∵ The income taxes is 22% of her income

∵ Her income is $3800

∴ The income taxes = $\frac{22}{100}$ × 3800

∴ The income taxes = $836

∴ The remaining of her salary after taxes = 3800 - 836

∴ The remaining of her salary after taxes = $2964

∵ She saves 8% of here salary

∵ Her salary after taxes = $2964

∴ Her savings = $\frac{8}{100}$ × 2964

∴ Her savings = $237.12

∴ The remaining of her salary after saving = 2964 - 237.12

∴ The remaining of her salary after saving = $2726.88

Katie has $2726.88 to spend each month after taxes and savings
