Distance=speed x time
so it would be 28 x 6=168
Answer: B: (y + z = 6) × -5
Step-by-step explanation:
if you multiply 'y' by -5 it turns into -5y. Therefore when you add -5y and 5y together, you get 0y which is what you want when eliminating the y-term.
Answer:
Please check out the attachments below to get the answer
Given:
x y
0 40
4 120
y = fixed amount + v(x)
y = 40 + v(0)
y = 40
y = 40 + v(x)
120 = 40 + v(4)
120 - 40 = v(4)
80 = v(4)
80/4 = v
20 = v
y = 40 + 20x
The fixed amount charged is 40.
The variable amount is 20 per day.
