Which function below is the inverse of f(x)= 3x+5/7

Ipatiy [6.2K]

Inverse
replace f(x) wih y
solve for x
replace x with f⁻¹(x) and y with x

so

f(x)=3x+5/7
replace
y=3x+5/7
solve for x
minnus 5/7 both sides
y-5/7=3x
divide both sides by 3
$\frac{y- \frac{5}{7} }{3}$ =x
replace with f⁻¹(x)

f⁻¹(x)= $\frac{y- \frac{5}{7} }{3}$

Wittaler [7]

Answer:

about 48.6%

20 women's shoes are athletic.

35 women's shoes are formal.

52 women's shoes are casual.

The total number of women's shoes is 107. So the probability that a randomly selected one is casual is:

P = 52/107

P ≈ 48.6%
