allochka39001 [22]

When y varies inversely with x, we have the follow equation:

y = kx

k = constant of variation

To find k, plugin the values for y = -4 and x = 7 and then solve for k

y = kx
-4 = k7
-4 / 7 = k7/7
-4 / 7 = k
k = -4 / 7
Now that we found k, we write the equation that relates the variables like below
$y = -\frac{4}{7}x$

I need a staight answer, A or B and why

ohaa [14]

Answer:

The answer is A

Step-by-step explanation:

You are not changing -14 into 14, you are just simply saying that you are adding more negative to -14, so instead of saying minus 6, you are saying adding -6. you are still going down on a number line either way.

What is the greatest common factor??

Mamont248 [21]

Answer:

Step-by-step explanation:

3 is the only option that goes into 39 and 6. If you have 2x's in the first set and 4 in the second, you can't take out 4 if you only have 2 in the first set. Same goes for the Y's. If you have 2 y's and try to take out 3. It won't work. So, your GCF is option D.
