Question

Y varies directly as to x. When x = -8 y = 6. Find y when x = 10

Answer 1

\[\huge \bf y=k \times x\]
where k is any number(resultant)
so,
\[\huge \bf k=\frac{y}{x}\]

If x=-8 and y=6,
\[\huge \bf k=\frac{6}{-8}=\frac{-3}{4}\]

Answer 2

If x=10 and y=?,
\[\huge \bf k=\frac{y}{x}=\frac{y}{10}\]
\[\huge \bf \frac{-3}{4}=\frac{y}{10}\]
now solve for y.

Answer 3

can you solve it? @balokkk

Answer 4

so the answer is -7.5? @mayankdevnani

Answer 5

\[\huge \bf 4y=-30\]
By cross multiply ^^^

divide 4 on both the sides,
\[\huge \bf y=\frac{-30}{4}=-7.5\]
you are correct @balokkk
