The true statements about the function y = 3x are I, II, IV ⇒ 4th
Step-by-step explanation:
The direct variation is:
- A mathematical relationship between two variables that can be expressed by an equation in which one variable is equal to a constant times the other
- The constant is called the constant of variation
- The direct variation is represented graphically by a line passes through the origin
- If y varies directly with x, then the equation of variation is y = kx, where k is the constant of variation
∵ y = 3x
- One variable is equal to the product of a constant and the
other variable
∵ The equation is in the form of the direct variation
∴ The function is a direct variation ⇒ I
∵ The direct variation represented by a line passes through the origin
∴ y = 3x is represented graphically by a line passes through the origin
∴ The function goes through the origin ⇒ II
∵ y = 3x is a direct variation
∴ 3 represents the constant of variation
∴ The constant of variation is not 1/3 ⇒ III
∵ y = 3x
∵ x = 2
- Substitute x by 2 to find y
∴ y = 3(2)
∴ y = 6
∴ y is 6 when x is 2 ⇒ IV
The true statements about the function y = 3x are I, II, IV

Answer: A ratio is one thing or value compared with or related to another thing or value; it is just a statement or an expression, and can only perhaps be simplified or reduced. On the other hand, a proportion is two ratios which have been set equal to each other; a proportion is an equation that can be solved.

It's too short. Write at least 20 characters to explain it well.
First you have to divide 21.75 and 3 to find out how much each hour costs. which would be 7.25. then you would divide 145 by 7.25 to find out how many hours you would work.
so the answer is 20.
