Question

HELP ASAP!! Write the direct variation function given that y varies directly with x, and y = 16 when x = 4.

Answer 1

Explanation:

X and y =4 so X+y is gonna be 4 X+y+16= and 16 times 4 is 64 so the answer is 64

Answer 2

Explanation:

If two variables are directly proportional, it means that an increase in the value of one variable would cause a corresponding increase in the other variable. Also, a decrease in the value of one variable would cause a corresponding decrease in the other variable.

Given that y varies directly with x, if we introduce a constant of proportionality, k, the expression becomes

y = kx

If y = 16 when x = 4, then

16 = 4k

k = 16/4 = 4

Therefore, the direct variation function is

y = 4x
