Answer: All x-coordinates are different, so this relation is a function.
Having the same y value more than once is not a problem for a function.
"This (does not/does) represents a function because different (x values/y values) can have the same (x values/y values)."
Step-by-step explanation:
10.5% of 678 =
0.105(678) = 71.19 <==

The flat fee that the store charges is $14 and the cost for 7 hours is $56
A linear equation is on the form:
y = mx + b
where y, x are variables, m is the rate of change and b is the initial value of y.
let f for the total rental cost of a vacuum cleaner for x hours
Using the points (1, 20) and (3, 32) from the table:

The flat fee that the store charges is $14
The reasonable domain is 1 ≤ x ≤ 12
The cost for 7 hours is:
f(7) = 6(7) + 14 = 46

Answer:
x=12
Step-by-step explanation:
you just have to add 2 to both sides to get x by itself and 10+2=12. therefore, x=12
