Convert inches into feet. (12 inches = 1 foot)
360/12 = 30 feet
Regina can take yoga classes at community center as it would cost her less money.
Step-by-step explanation:
No. of classes per week = 2
Classes in 6 weeks = 2*6 = 12 classes
Cost of classes at community center = $72
Additional one time fee = $12
Total cost at community center = 72+12 = $84

Answer:
f⁻¹(x) = x+2 / 3
Step-by-step explanation:
Given function is:
f(x) = 3x-2
We have to find the inverse of the given function.
Put y = f(x) in given function, we have
y =3x-2
Adding 2 to both sides of the above equation we have
y+2 = 3x-2+2
y+2 = 3x
Dividing by 3 to both sides of the above equation, we have
y+2 / 3 = 3x / 3
y+2 / 3 = x
Put x = f⁻¹(y) in the above equation we have
y+2 / 3 = f⁻¹(y)
Swapping equation we have
f⁻¹(y) = y+2 / 3
Replace y with x we have
f⁻¹(x) = x+2 / 3 which is the answer.
