Step-by-step explanation:
7 is the coeffiecient
3 is the constant
Turn f(x) into y so the equation is y=x+2. Now switch their places so it is x=y+2. Now solve for y. The answer is y=x-2.
The equation for simple interest is:
A=P(1+rt)
Where:
A=amount
P=principal amount
r=rate as a decimal
t=time
So:
660(1+(0.035×5))=$775.50
The first table is proportional. Y is 4 times X. The second table is 1.25 times X
Answer: 14.51 gallons i think.
