divide both sides by 7 to get x alone
84/7 = 12
B.12
Answer:
6hrs
Step-by-step explanation:
First, we have to put the information given to us about the money they earn into an expression
let x represent the number of hours Kini and Duke work and y represent the total amount of money they earn in a week.
y(kini) = 9x + 8
y(duke) = 7.5x + 17
Now we subtract the x values and the constant values
9x - 7.5x = 1.5x
17 - 8 = 9
Make these into an equation
1.5x = 9
Divide both sides by 1.5 so x(the number of hours the both work) can stand alone.

x = 6 hrs
Answer:
Domain: All real numbers
or

Range: All real numbers
Or

Step-by-step explanation:
The given function is 
This a polynomial function of degree 1.
Polynomial functions are continuous everywhere.
The function is therefore defined for all real values of
.
The domain is 
If we let 
Then,
.
is also defined for all real values of
, hence the range is also all real numbers or
