What is the x- value?

Step-by-step explanation:

x = 1

Step-by-step explanation:

The system of equations is expressed as

- 4x - 2y = - 4- - - - - - - - - - - - - - - -1

y = - x + 1- - - - - - - - - - - - - - -2

We would apply the method of substitution by Substituting equation 2 into equation 1. It becomes

- 4x - 2(-x + 1) = - 4

- 4x +2x - 2 = - 4

- 2x - 2 = - 4

Adding 2 to the left hand side and the right hand side of the equation, it becomes

- 2x - 2 + 2 = - 4 + 2

- 2x = - 2

Dividing the left hand side and the right hand side of the equation by

- 2, it becomes

- 2x/- 2 = - 2/-2

x = 1

Substituting x = 1 into equation 2, it becomes

y = - 1 + 1

y = 0

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.
