Answer:

Step-by-step explanation:
Given
Dimension: 4.75in, 4.75in and 28.5in
<em>[The complete dimension is missing from the question]</em>
Required
Calculate the volume
The volume is calculated as thus:


--- approximated
Answer:
The answers are options A and B
First solve the inequality
7x < 21
Divide both sides by 7
That's
7x/7 < 21/7
x < 3
The values that satisfy the inequality are
1 and 2 since they are both less than 3
Hope this helps you.
It would be 0 because as you go along it doesn't go up but keeps moving. An undefined slope is up and down/vertical.
The difference means subtract
5y means product or 5 times y
5y - 15
