Answer:
32
Step-by-step explanation:
You need to work backwards to solve this equation!
9 - 17 = -8
w / -4 = -8
32 / -4 = -8
Which means that w = 32
To solve this, plug in your given x value (9 minutes) in for x in your formula, so w(x)=60(9)=540 words as your answer.
Answer:
a = 20, b = 5
Step-by-step explanation:
| x-a| ≥ b
| x - 20 | ≥ 5
a = 20 ... car speed
b = 5 ... either 5 m/h above or lower than the limit speed 20 m/h
