<h3>How to plot the function?</h3>
The function is given as:
h(x) = | -4, x < 3
| x + 5, x >= 3
The above function is a piecewise function.
It has 2 separate functions at two domains
This means that we plot the sub-functions in the piecewise function at their respective domain

We can convert 20km to 20,000m. Then, we can subtract 800m (walking distance) from 20,000m which would result in 19,200m. Then we can put 19,200m and 20,000m as a fraction (19200/20000). Before we can multiply it by 100 to make it in the percentage form, we can get rid of 2 zeroes for both number making it 192/200 and then further simplifying it to 24/25 by dividing both numbers by 8. Finally to get the percentage we can multiply 24 and 100 (2400) and then divide the result (2400) by 25. The final answer is 2400/25=96 meaning he cycled 96% of the journey and walked 4% of the journey (100-96=4).
P=2l+2w
42=2l+2 (10)
42=2l+20
-20 -20
22=2L
22/2 = 11
length = 11 inches
Answer:
Both trains are traveling at 90 miles per hour.
Step-by-step explanation:
We are told that the rate is the same for both trains, and we know that the distance traveled by train a plus the distance traveled by train b equals 585 miles.
We will use 
formula to solve this problem.
Train A: 
(Using 2.5 instead of 2 and 1/2)
Train B: 
We can set an equation to solve for rate R of trains as:
Therefore, rate of both train a and train b is 90 miles per hour.
The answer is E. To find a line perpendicular to another, you have to take the reciprocal of the original slope. That will give you the slope of the new line. Then the intercept (in this case -2) stays the same.
