Answer:
h less-than 2
Step-by-step explanation:
Let
h ---> the number of hours
y ---> the total charge in dollars
we know that
The linear equation is slope intercept form is equal to
![y=mh+b](https://tex.z-dn.net/?f=y%3Dmh%2Bb)
where
m is the slope or unit rate of the linear equation
b is the y-intercept or initial value of the linear equation
we have
<em>Grayson</em>
The slope is equal to ![m=\$35\ per\ hour](https://tex.z-dn.net/?f=m%3D%5C%2435%5C%20per%5C%20hour)
The y-intercept is ![b=\$35](https://tex.z-dn.net/?f=b%3D%5C%2435)
so
The total charge is equal to
----> equation A
<em>Ian</em>
The slope is equal to ![m=\$45\ per\ hour](https://tex.z-dn.net/?f=m%3D%5C%2445%5C%20per%5C%20hour)
The y-intercept is ![b=\$15](https://tex.z-dn.net/?f=b%3D%5C%2415)
so
The total charge is equal to
----> equation B
For what number of hours does Grayson charge more than Ian?
The inequality that represent this situation is
![35h+35 > 45h+15](https://tex.z-dn.net/?f=35h%2B35%20%3E%2045h%2B15)
solve for x
Group terms
![35-15 > 45h-35h](https://tex.z-dn.net/?f=35-15%20%3E%2045h-35h)
![20 > 10h](https://tex.z-dn.net/?f=20%20%3E%2010h)
Divide by 10 both sides
![2 > h](https://tex.z-dn.net/?f=2%20%3E%20h)
Rewrite the expression
----> h less than 2 hours
Answer:
8
Step-by-step explanation:
It appears your table includes points (4, 9) and (7, 33). The average rate of change on the interval is the slope of the line between these two points:
m = (y2 -y1)/(x2 -x1)
m = (33 -9)/(7 -4) = 24/3 = 8
The average rate of change is 8.

Answer:
1 2/3
Step-by-step explanation:
If you make all of their denominators 15, you would get 12/15 + 10/15 + 3/15, which is equal to 25/15, which is 1 10/15. 10/15 simplifies to 2/3, so the answer is 1 2/3.
