Directly proportional to x.
<h3>What is propotionality?</h3>
- In algebra, proportionality is the equality of two ratios.
- A and B are in the same ratio as C and D in the formula a/b = c/d.
- When one of a proportion's four quantities is unknown, a proportion is often built up to resolve the word problem.
- By multiplying one numerator by the opposing denominator and equating the result to that of the other numerator and denominator, the equation can be solved.
- Any relationship that has a constant ratio is said to be proportionate. For instance, the ratio of proportionality is the average number of apples per tree, and the amount of apples in a crop is proportional to the number of trees in the orchard.
Acc to our question-
- If two variables' ratios (yx)
- (x and y) have the same value as a constant (k=yx)
- therefore the ratio's variable (y) in the numerator is the sum of the other variable and the constant (y=k:x).
- With a proportionality constant of k, it is claimed that y is directly proportional to x in this instance.
Hence,Directly proportional to x.

Volume of a cylinder:
The volume of a cylinder with radius r and height h is given by:

A cylinder has a height of 12 inches and a radius of 1.5 inches.
This means that 
What is its volume?

It's volume is of 84.78 cubic inches.
Answer:
B
Step-by-step explanation:
So, we know that this inequality has an "at most" in its phrase, therefore signifying the sign x <em>≤</em> 5. Since the x is in the left side without any negatives, so <em>the arrow goes left, and the circle is filled</em>. So, B.
