***When x=-5⇒2*(-5)²+6*(-5)-8=12⇒B. statement is true.

***2x²+6x-8 can also be written as (x+5)*(2x-4)+12 so (x+5) is a factor of 2x²+6x-8⇒C. statement is true.

Darrin graphs the following inequality: y > -3x -5. Does the side of the line with all solutions (the shaded region) include

Anarel [89]

Yes it does include the test point (0, 0)

equation: y > -3x -5

<h3>Find y-intercept:</h3>

y > -3(0) -5

y > -5

<h3>Find x-intercept:</h3>

y > -3x -5

<u>switch sides</u>

-3x - 5 < 0

-3x < 5

<u>Multiply both sides by -1 reverses the inequality</u>

x > -5/3

Thus, the following (0, 0) comes under the following x > -5/3 and y > -5
