Solve system by elimination
-9x+7y=22
9x-5y=-26

The solution would be (-4, -2)

Step-by-step explanation:

To find this simply add the two equations together.

-9x+7y=22

9x-5y=-26

2y = -4

y = -2

Now we have the y value, we can solve for the x value.

9x-5y=-26

9x-5(-2)=-26

9x+10=-16

9x=-36

x = -4

no not all of them.

step-by-step explanation:

some of them have a square base.

the correct answer is

c. 4

step-by-step explanation:

the given polynomial is

the degree of the polynomial is the highest exponent which is 4.

the -4 is called the leading coefficient.

this polynomial has only one term so it is a monomial.

the correct answer is option c.
