Y-1/6x=4 and 6y+x=-24

y = 1/6x + 4 and y = -1/6x - 4

Step-by-step explanation:

y-1/6x=4

You want to isolate y by adding -1/6x to the other side

y = 1/6x + 4

AND

6y+x=-24

First, to isolate y, you want to subtract x over to the other side

6y= -x -24

Then you want to divide all of the equation by 6 to isolate the y.

y = -1/6x - 4

(a) the volume of the cone is 20/3 in3

hence, option a is correct.
