25$ is the flat fee. 50$ is the amount charged per hour. Therefore the equation is C=25+50h where c is the total cost and h is the amount of hours.
C=25+50h
To find the amount of money for 8 hours simply plug in 8 for h and you get 400. Don't forget to add the flat fee of 25. The total cost for 8 hours of service is 425.
To find the amount of money for 10 hours of work, plug in 10 for h and you get 500. Add 25 to 500 and you get 525 for a total of 10 hours of work.

Answer:
The unit rate of change is of 
Step-by-step explanation:
We are given a set of points (x,y).
To find the unit rate of change, we take two points, and divide the change in y by the change in x.
Points (4,9) and (8,12)
Change in y: 12 - 9 = 3
Change in x: 8 - 4 = 4
Unit rate of change:
Answer:
2/3
Step-by-step explanation:
Sum of internal angle of a triangle is 180°.
3x° + 2x° + 5x° = 180°
10x° = 180°
x= 18°
m L = 3x
3. 18 = 54°

Answer:
The equation would be y - 9 = 17(x + 7)
Step-by-step explanation:
In order to find the equation of this line, we have to use the slope formula to find the slope.
m (slope) = (y2 - y1)/(x2 - x1)
m = (9 - -8)/(-7 - -8)
m = (9 + 8)/(-7 + 8)
m = 17/1
m = 17
Now that we have that, we can use it along with the second point to put into the point-slope equation.
y - y1 = m(x - x1)
y - 9 = 17(x - -7)
y - 9 = 17(x + 7)
