Answer:
This means that 12 is the slope of the line y = 12x - 19.
Answer:
-43
Step-by-step explanation:
-2x2 + 2x - 3?
Let x = 5
-2 (5)^2 +2(5) -3
-2 (25) +10 -3
-50 +10 -3
-43
43x7=301
12x9=108
10x6=60
9x7=63
7x5=35
6x3=18
0x8=8
30x3=90
11x8=88
73x2=219
83x5=415
16x8=128
392x7=2,744
29x4=116
761x9=6,849
4,829x6=28,974
12x7=84
25,500x4=102,000
From the information given,
3 pounds = $18
Therefore, 1 pound = 18/3 = $6 (this can be treated as a constant of proportionality) such that,
Cost,C = 6*Weight, W (pounds)
Equation;
C = 6W, where C = Cost in $, and W = Weight in pounds.
