Step-by-step explanation:

3x - 7y + 12 = 5x - 9

-7y = 5x - 3x - 9 - 12

Alex

For this case we want to do the following operation:

-3/5 divided by 7/16 and we can do this:

$-\frac{3}{5}\cdot\frac{6}{7}=-\frac{18}{35}$

And then we can simplify and we got:

$-\frac{18}{35}$

HELP PLEASE <br><br> Complete the table given one rule <br><br> Rule: y=4x

I am Lyosha [343]

The rule is that y equals 4 times x.

Whatever value of x you have, multiply it by 4 to find the corresponding y value.

If x = 3, y = 4 * 3 = 12

If x = 4, y = 4 * 4 = 16

If x = 5, y = 4 * 5 = 20

The table looks like this:

x y
