30 simple ! which correctly describes how the graph of the inequality −4y − x ≥ 7 is shaded? above the solid line below the solid line above the dashed line below the dashed line

Below the solid line.

Step-by-step explanation:

When you solve for y, you will have a less than or equal to sign, so the shading is below the line.

Below the solid line

Step-by-step explanation:

−4y − x ≥ 7

We need to solve for y

Add x to each side

−4y − x +x≥ 7+x

-4y   ≥ 7+x

Divide each side by -4.  Remember to flip the inequality

−4y/-4 ≤ (7+x)/-4

y ≤ -1/4 x - 7/4

Y is less than or equal to the value so the line is solid (equals sign)

and below  ( less than)

step-by-step explanation:

answer: (c) m∠qpo + (2x + 16)° = 180°

step-by-step explanation:

the opposite angles of a quadrilateral are supplementary.

so, ∠o + ∠q = 180°   and   ∠p + ∠r = 180°

since ∠r = 2x + 16°, we can use substitution as follows:

∠p + ∠r = 180°

∠p + (2x + 16)° = 180°
