Answer:
See explanation
Step-by-step explanation:
A
x + 3y = 5
(x, y) = (2,1)
x + 3y = 5
2 + 3(1) = 5
2 + 3 = 5
5 = 5
The equation is true
B.
y = –x + 3
(x, y) = (2, 1)
y = –x + 3
1 = -2 + 3
1 = 1
The equation is true
9514 1404 393
Answer:
increase
Step-by-step explanation:
Your cost function appears to be an exponential function of the form ...
c(x) = (initial cost)·(growth factor)^x
When the growth factor (1.03) is greater than 1, it means the exponential function is increasing with x (time).
The cost function increases with time.

Answer:
20
Step-by-step explanation:
start by dividing 18 from 120(to find the amount of 18's in 120)
120 / 18 = 6.<u>6</u>
meaning there are 6.<u>6</u> sets of 18 in 120
multiply 3 by 6.<u>6</u>(since there's 3 miles for every 18 minutes)
3 x 6.<u>6</u> = 20
