Answer:
c=357
Step-by-step explanation:
3220=9c=7
Move variable to the left-hand side and change its sign
-9c+3220=7
Move constant to the right-hand side and change its sign
-9c=7-3220
Calculate the difference
-9c=-3213
Divide both sides of the equation by -9
c=357

Answer:
(-∞, ∞)
Step-by-step explanation:
As you can see for each value of x , f(x) is defined
example , for x = -8000 , f(x) is defined to be -7999.
for x = 0 , f(x) is defined to be 1.
for x = 8000 , f(x) is defined to be 8001.
Also,
By its graph , Which is a straight line , So, it is defined everywhere
Thus,
its domain is (-∞, ∞)
Answer:
40 miles a day
Step-by-step explanation:
The difference in fixed charge is $20; the difference in mileage charge is $0.50 per mile. So it will take $20/$0.50 = 40 miles for the extra mileage cost to eat up the savings in fixed cost. At that mileage, both companies will charge the same amount:
A: 90 + 0.30·40 = 102
B: 70 + 0.80·40 = 102
