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
Answer:
The answer is A = 14 B = 4 14 - 4 = 10 I think.
Step-by-step explanation:
It's not a sum its a difference because this is a subtraction problem I think.
Answer:
$20d = c
Step-by-step explanation:
Since the cost is $20 per day, $20d ($20 for how many days) would be the start of the equation.
C = cost, and $20d will determine the cost, so $20d = c
is your final answer/equation.

if you can get a bag of 12 goldfish for 3 dollars then for 1 dollar you could get 1/3 of 12 goldfish or 4 goldfish. 1 dollar got you 4 fish so one fish should cost 1/4 of a dollar or 25¢
