A direct variation function contains the points (–8, –6) and (12, 9). Which equation represents the function? y = –negative StartFraction 4 Over 3 EndFraction equals StartFraction 4 Over 3 EndFractionx y = –k equals negative StartFraction 3 Over 4 EndFraction x. x y = k equals StartFraction 3 Over 4 EndFraction x. x y = k equals StartFraction 4 Over 3 EndFraction x. x

For this case we have that by definition, a direct variation is of the form:

Where "k" is the constant of proportionality

If the following points belong to the variation (-8, -6) and (12,9) then we have to replace one of the points we find the value of "k":

Thus, the function is given by:

y = \frac {3} {4} x

whatever you can spend with $11.53 or under.

step-by-step explanation:

20 - 8.47 = 11.53. take away the money he used for lunch from the starting amount of 20.

x=17

step-by-step explanation:

solve 3x-24=x+10

then that makes it 2x=34 because you subtract an x from both sides to get rid of the one on the right, and then you add 24 to both sides to get rid of the 24 on the left

divide by both sides by 2 to get your answer so that you can get your answer
