Answer: The answer C i.e. no solution is the right answer

Step-by-step explanation:

Given system of equations:

2x-6y=12 ............[1]

-x+3y=-2 ...............[2]

When we multiply the second equation by 2

we get

-2x+6y=-4

Multiplying both sides by -1

2x-6y=4 ..........[3]

On comparing [1] and [3]

we see that their coefficients of variables are same but the value

on the other side is different

which is not possible for a equation

Hence the system has no solution

If y varies directly as x, and y=8 when x=3, find y when x=15.

Crank

Answer:

y=40

Step-by-step explanation:

The formula for Direct Variation is y=kx or k=y/x. In this case I would use k=y/x. If you're y is 8 and x is 3, this means that K=8/3. Using this, we know that X=15. We have to find a Y value so that the fraction with an x of 15 simplified is 8/3. To do this you would write 8/3 and y/15. Now cross multiply to get 3y=120. Divide by 3 to get y=40.
