jerry is driving at a steady speed on an inter-state highway. 2.5 hours after he starts, he notes that he has driven 150 miles. after 5.5 hours, he notes that he has covered 330 miles.

which graph shows how his distance covered varies with time?

a)b)c)d)

Step-by-step explanation:

Jerry is driving at a steady speed on an highway.

After 2.5 hours he has driven = 150 miles.

speed = = 60 miles/hour

then after 5.5 hours he has covered 330 miles.

speed = = 60 miles/hour

Total time he has driven = 2.5 + 5.5 = 8 hours

total distance he covered = 150 + 330 = 480 miles.

Therefore, after 2.5 hours he covered 150 miles and after 8 hours he covered 480 miles with an steady speed of 60 miles/hour.

Graph A shows his constant speed and his distance covered varies with time.

answer: 177/8

step-by-step explanation:

part a

x     y

0     8

1     7.5

2     7

3     6.5

4     6

5     5.5  

for every hour i deducted .5 inches from the length of the candle

part b

it is a function because for every x value there is only one y value

part   c

for every x value there is only one y value
