Answer:
12
Step-by-step explanation:
Equation y=40x+420
plur in 900 to the y
900=40x+420
subtract
480=40x
divide
x=12
H(x) = 1/4x would be the inverse
In this case just do it left to right, as multiplication comes before addition/subtraction. So 7x3x2+5-3=21x2+5-3=42+5-3=47-3=44=k.
Answer:
x= 5

12x= 52+8
12x= 60
x= 60/12
x= 5
