If y varies directly as x and y and y= 48 when x = 16 write the variation equation for this situation?
y varies directly as x and y ?
not sure what that means? i know y can vary directly with x, but what does it mean "y varies directly with x and y" ? that would mean y = kxy
oh no do the normal equation
oh ok if y varies directly with x then \[y = kx\] let x = 16 let y = 48 solve for k
right, that is how you will solve for k. what answer do you get for k ?
3 but in the question it doesnt ask for k and i did write 48=k16 and got it wrong
well we didn't answer the question yet. we can't answer the question without knowing what k is since we solve for k = 3 then we know y = kx y = 3x
now i see the problem... thank you!
