Answer:
After 59 months the new dryer will pay for itself.
Step-by-step explanation:
Let the new clothes dryer takes 'x' months to pay for itself.
Then the operating cost of the new dryer will be = 15x
Since cost of the new dryer = $590
So, total cost of the dryer in x months = $(590 + 15x)
Now we know old dryer's operating cost is = $25 per month
So, operating cost for x months = 25x
By the time when new dryer's total cost becomes equal to the old dryer's operational cost, the new dryer will pay for itself.
Now we can get the value of x by equating the old dryer's operational cost and the new dryer's total cost.
25x = 590 + 15x
25x - 15x = 590
10x = 590
x = 
x = '59 months'
Answer:
f=4
Step-by-step explanation:
1) first we have to get the "f" by itself. to do this we subtract the 1 from the right side of the equation.
2) and what you do to one side you ALWAYS do to the other side!!! so subtract 1 from the 5 also
3) this leaves you with 4=f

10 liters of gas fill one tank.
x liters of gas fill x/10 tanks.
35 liters of gas fills 35/10=7/2 tanks
7/2 can also be written as 3.5 or the mixed number (3 and 1/2)
Answer:
Step-by-step explanation:
We start by subtracting 
from both sides of the second inequality:
Therefore, we conclude that:
Therefore, every point that satisfies the system has a 
-coordinate greater than 
.
The slope =0. Horizontal lines have a slope of 0
