Answer:
m=-2/3 b=-3
Step-by-step explanation:
Answer:
Step-by-step explanation:
The rate in this case is slope of the line. The formula of a slope is m = 
(10, 325)
(4, 130)
m = 
= 
= 32.5 miles per gallon
The actual rate is less (better) than advertising.
Answer:
A. 3.2% faster
B. 3.3% slower
C. 103.3%
Step-by-step explanation:
In order to find this out, we need to take the differences and divide them by the comparative time. So, in the first one, we take the difference (.32) and divide it by Hines time.
.32/9.63 = 3.2%
In the second, we take the difference and divide by Bolt's time.
.32/9.95 = 3.3%
And finally, in the last one, we take Hines' time and divide by Bolt's.
9.95/9.63 = 103.3%
