Question

HELP!!! Write the direct variation of the equation if y varies directly with x and y = 45 when x = 9.

Answer 1

Hmm do you really need help, this is exactly same as the previous one

Answer 2

No it's not....

Answer 3

\[y = k * x\]
Now find the value for k.
\[45 = k*9\]
\[k = \frac{45}{9}\]\[k=5\]

now, insert that into original equation.
\[y = k * x\]\[y = 5x\]

Answer 4

Thanks! Can you help me with another?
