I solved it but don’t know how to show my work
$14.06, we can find the total cost by multiplying that by 30, to giveus $421.80 if there were no discount. We can find the discount price in two equivalent ways, either by finding 30% of 421.80 and subtracting that,or by finding 100% - 30% = 70%. That is, the new price will be 70% of the old price. Since they wantthe new price, and not the discounted amount, it is simpler to use 70% 70% = 70/100 or 0.7. 0.7 x 421.80 = $295.26
The coordinates of the midpoint of line segment AB:

We are given that the suitcase is 24 inches long and 18
inches high. Assuming a regular rectangular shape, the diagonal can be calculates
using Pythagorean theorem, that is:
diagonal^2 = 24^2 + 18^2
diagonal^2 = 900
<span>diagonal = 30 inches</span>
Answer:
(5,4) & (8,-10)
Step-by-step explanation:
First step:
You can use any number you want for b (I used 4)
Make x=0
Make y=0
Subtract 4 from both sides
Divide both sides by 
Second step:
In order to make a line perpendicular to another the slope of the second line will be the negative inverse of the first line. So 
will be 
for the second line.
Then you just need to repeat the process in first step to get the intercepts. (Again I used a random number like -10 for b)
