First you need to set up an equation y = mx + b. m would be the monthly charge and b would be the one time fee. x represents the number of months.
To solve for the number of months with a total price of 240 we substitute 240 in for y and solve for x.
240 = 25x + 40
subtract 40 from each side
200= 25x
divide by 25
8 = x
8 months
10 + 7r = 45
7r = 35
r = 5
5 miles
What are the options for the expressions?
40 since it is in the tens place
Answer:
g(4) = - 16
Step-by-step explanation:
Substitute x = 4 into g(x) , that is
g(4) = - 7(4) + 12 = - 28 + 12 = - 16
