Suppose that y varies directly with x and y = 12 when x = -2. What is x when y = -6?
Vesna [10]
X=1

Explanation:
Conduct a ratio, -2/12=x/-6

You have to find the x in this ratio so you will multiply -2 and -6 together, and multiply 12 and x together and make them equal to eachother. It would look like this.
(-6)(-2)=12x
12=12x
x=1

I hope this is right and I’m sorry if I’m wrong:((

Rearrange the equation so uuu is the independent variable.<br> -12u+13=8w-3
Sunny_sXe [5.5K]

Step-by-step explanation:

- 12u + 13 = 8w - 3 \\  - 12u + 13 + 3 = 8w  \\  - 12u + 16 = 8w  \\ w =  \frac{ - 12u + 16}{8}   \\ w =  \frac{ - 3}{2} u + 2

I hope that is useful for you :)
