Question

If y varies directly as x, and y =15 as x= -3, find y for the x-value of 6.

1. -30
2. -32
3. -34
4. -36

Answer 1

Answer:

the answer is -30.

Step-by-step explanation:

for each x-value, you will multiply it by -5 to get your y-value. i say this because if y-15 when x=-3, if you divide the x from y (so 15/-3) you get -5 which is the number in which y varies by. so you will take 6 and multiply it by -5 which gives you -30.
