Enter the y coordinate of the solution to this system of equations. -2x+3y=-6 5x-6y=15

julia-pushkina [17]

Y coordinate on solving both equations comes out to be 0
-2x+3y=-6
3y = -6+2x
put the value of 3y in equation 2nd
5x-2(-6+2x) =15
5x+12-4x = 15
x=3
put value of X in 3y = -6+2x
3y = -6+2*3 = -6+6 = 0
thus y = 0

Is 7/9 a rational number ?

zzz [600]

Answer:

Yes.

Step-by-step explanation:

Rational numbers can be represented as fractions with integers. The denominator must not equal 0.

$\frac{7}{9}$ is already in this form. This means that it's a rational number.

Hope this helps.
