Given: x varies directly to y, find x when y=90 and k=10.
Answer:
Step-by-step explanation:
Find x using the equation x=ky where kis the constant of variation since x varies directlyas y. In this case, since the constant of variation is already given, then we only have to multiply k by y to find the value of x.
Therefore, the value of x is equal to 900.

The statements:
“y varies directly as x”
“y is directly proportional to x”
“y is proportional to x”
may be translated mathematically as y=kx where k is the constant of variation.
