I think its A!! But im not sure
It’s a because the total of x and y is 6.80 and the second equation is how much each are and the total being 7.

Answer:
a) y = (x+2)/3
b) 5
Step-by-step explanation:
f^-1(x) means "f inverse of x". To find the inverse, we simply:
a ) f(x) = 3x -2
y = 3x - 2 --> because f(x) is the same thing as y
x = 3y - 2 --> to find the inverse, we simply just switch x and y
x + 2 = 3y
y = (x+2)/3
b) f^-1(13)
f^-1(13) = [((13) + 2)/3]
f^-1(13) = (15)/3
f^-1(13) = 5
$4.50
divide $1.35 by 3 to find the initial cost and then time that number by 10 and you get $4.50 bye now bukaroo
First do the -2+3 since its in the Parentheses. So now your left with 1 times 3 >12.
Then you do the multiplication so now you're left with 3>12 which isn't true.
