To simplify this expression we need, at first, to find like terms.
<span>-3x+5y-2+7x-8y</span><span>-3x+5 = (</span>-3x+7x)+ (5y-8y) -2+5 = 4x + 3y +3
4x + 3y +3 is the answer.
Answer: $122.50
Step-by-step explanation:
We know the difference between the time the employee clocked in and clocked out = 1200 - 0800 = 4 hours
The next clock in and out = 17:30 - 12:45 = 4 hours, 45 minutes.
These times combined = 8 hours, 45 minutes
minutes in an hour = 
of an hour.
The total time worked was 8 hours.
Multiply 8.75 × $14 = $122.50
I am not a professional, simply using prior knowledge.

Answer: d
Step-by-step explanation:
use the formula 
Answer:
option: C is correct.
Step-by-step explanation:
since, we are given a parent function f(x) as: f(x)=x.
We are asked to find what change will occur in the function when the parent function f(x) is replaced by f(9x).
let g(x) be the function formed by replacing f(x) with f(9x) i.e.
g(x)=f(9x)=9x.
clearly the slope of the function g(x)=f(9x) is 9. ( since on comparing the equation with the slope intercept form y=mx+c; where m is the slope of the line and c is the y- intercept).
whereas the slope of the function f(x)=x is 1.
Hence there is an increment of slope by a factor of 9.
Hence, option C is correct.
The answer would be C because 24-3=21 then you would do 21/1.50=14
