The value of y varies directly with x. When y= 75, x= 2 What is the value of y when x
is 2 1/4

The correct answer will be d. -4

The question is kind of confusing. if it's asking how many variations of answers can you give. then do 4^5 for your answer.this would be something like the first question could be a and the 2nd c or first b next c etc. if you can, ask the teacher for a better confirmation of what it's asking. if i'm assuming correctly what it's asking, it's 625 different variations.
