Y = 3x + 5, x = -4 / So, what would the y in the equation equal to ?

Step-by-step explanation:

y= 3 (-4)+5

y=   - 12+5

y= -7

-7

Step-by-step explanation:

Substitute x into the equation to get.

Y=3(-4)+5

Solve the right side.

y=-7

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°
