Answer:

3/7

Step-by-step explanation:

Use Y2-Y1/X2-X1

So, 7+2/7+14=9/21

9/21 can be simplified so divide both by 3 which leaves you with 3/7

Solve the system of linear equations using any method 6x+6y=-6, 5x+y=-13

Sergio [31]

Answer:

x=-3

y=2

Step-by-step explanation:

To solve this problem you can use the elimination method:

- Multiply the second equation by -6:

$(-6)5x+y=-13\\-30x-6y=78$

- Add both equations:

$6x+6y=-6\\-30x-6y=78\\-------\\-24x=72\\x=-3$

- Substitute the value of x into one of the original equations and solve for y:

$6(-3)+6y=-6\\-18+6y=-6\\6y=12\\y=2$

3 times 5 with a two on the top

jenyasd209 [6]

Ok so it could be
1. $\frac{2}{3 times 5}$
2. 3 timies $\frac{2}{5}$

ok if 1. then
$\frac{2}{3 times 5}$ = $\frac{2}{15}$

if 2. 3 timies $\frac{2}{5}$ = $\frac{6}{5}$

What is the constant variation in the equation 3y=6x? Explain. PLEASE HELP IM DESPERATE

lbvjy [14]

Hi Desperate!

anyways the equation for constant variation is y=kx
3y=6x is it, but we don't want the 3.
so we divide on both sides to cancel out the 3.
y=2x
