It is given that y varies directly as x. if y = 10 when x = 3 determine the constant of variation. it is given that y varies directly as x. if y = 10 when x = 3 determine the constant of variation. it is given that y varies directly as x. if y = 10 when x = 3 determine the constant of variation. v

Y varies directly as x means
y=kx
k is the constant of variation

10=k3
10=3k
divie both sides by 3
10/3=k

y=(10/3)x

the constant of variation is 10/3

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.
