Answer:
Step-by-step explanation:
5 = 2k
k = 5/2 = 2.5
The ratio is constant.
1. (-0,286; 0), (1,333; 0)
2. (0; -8)
Wendy = W
Connie = C
Tim = T
Equations
W = C + 4
C = T + 4
W + C + T = 45
Solution
Put W into the third equation
C + 4 + C + T = 45
2C + 4 + T = 45
Put T into the above equation
T = C - 4
2C + 4 + C - 4 = 45
3C = 45
C = 15
15 = T + 4
11 = T <<<< Answer
12, -12
21, -21
-11, 11
17, -17
-21, 21
