Answer:
16m + 2n + 4
Step-by-step explanation:
( −2n −2) + (6 + 8m) + (8m + 4n)
−2n + −2 + 6 + 8m + 8m + 4n
(8m + 8m) + ( −2n + 4n) + (−2 + 6)
16m + 2n + 4

Answer:
Step-by-step explanation:
Let n represent the number of copies made.
Let y represent the cost of making n copies.
If we plot y on the vertical axis and n on the horizontal axis, a straight line would be formed. The slope of the straight line would be
Slope, m = (66 - 48)/(197 - 50)
m = 18/147 = 0.122
The equation of the straight line can be represented in the slope-intercept form, y = mx + c
Where
c = intercept
m = slope
To determine the intercept, we would substitute x = 66, y = 48 and m = 0.122 into y = mx + c. It becomes
48 = 0.122 × 66 + c = 8.052 + c
c = 48 - 8.052
c = 39.948
The linear function that describes the cost of a printing job would be
y = 0.122n + 39.948
