Answer:
a=0, b=-4
Step-by-step explanation:
a+b=-4.....(1)
a-b=4.......(2)
(1)+(2): 2a=0
a=0
0+b=-4
b=-4
(a, b) =(0,-4)
y = x +3
When you examine the table, you see that each y-value is 3 more than the corresponding x-value. This is represented in the equation ...

b) 270 ≥ 40.18d + 3.75
Per day is a variable, so it's 40.18d
Per mile is also a variable so 0.05m
40.18d + 0.05m ≤ 270
40.18d + 0.05(75) ≤ 270
40.18d + 3.75 ≤ 270
