Answer:
c = 40 + 0.79m
Step-by-step explanation:
The base cost is $40.
So we have:
c = 40
Then, since an additional $0.79 is charged for every mile driven, we add:
+ 0.79m
So then our equation is:
c = 40 + 0.79m
where c = total cost
and m = number of miles driven
Answer:
y = 120
Step-by-step explanation:
y = kx ur finding k
8 = k 3 get k alone by dividing both sides by 3 --> 8/3 = k
k = 8/3
Y = 8/3 45 now your finding Y when x is 45
Y = 120
to make sure do 120 = 8/3 45 should equal the same
Answer:
(6, 1 )
Step-by-step explanation:
To determine which ordered pair is a solution
Substitute the x and y values into the left side of the equation and if equal to the right side then it is a solution.
(6, 1 )
3(6) + 9(1) = 18 + 9 = 27 ← Solution
(1, 8 )
3(1) + 9(8) = 3 + 72 = 75 ≠ 27
(1, 11 )
3(1) + 9(11) = 3 + 99 = 102 ≠ 27
(8, 1 )
3(8) + 9(1) = 24 + 9 = 33 ≠ 27
Then (6, 1 ) is a solution to the equation
