Answer:

-2x - y = -5 in slop intercept form would be <u>y = -2x + 5 </u>

Step-by-step explanation:

-2x - y = -5

first add -2x to the left side to move it to the right side because whatever you do to one side u do to the other.

-y = -5 + 2x

divide by -1 on the whole equation

y = -2x + 5 is your answer.

Please someone do this for me

nlexa [21]

Answer:

A = -12

B = -8

C = -4

Step-by-step explanation:

$y=2x-8$

x = -2

$y=2(-2)-8=-4-8=-12$

A = -12

x = 0

$y = 2 (0)-8=-8$

B = -8

x = 2

$y = 2 (2) -8 = 4-8 = -4$

C = -4

Hope this helps

1.Which expressions are polynomials? Select each correct answer. Pick more then one.

madreJ [45]

If all the power of the variables are greater than or equal to zero, then the expression is a valid polynomial.

So,

$7x^{7}-x-5$

$35x^{2}$

$\frac{x}{5}+2$

are polynomials.

$x^{2} -x\sqrt{2}$

2 + s

$4x^{2} +y$

are all polynomials.

If the degree of the polynomial is 3, then it is a cubic polynomial. If the number of terms of a polynomial is 3, then it is a trinomial.

Hence, $-5x^{3}-4x+1$ is a cubic trinomial.

The highest power is the degree.

Hence, degree of the polynomial is 2 + 4 = 6.
