2. Is the point ( -5,11) a solution to the following system of equations? Show your work.
y = -x + 6
y=-3x – 4

Yes it is

Step-by-step explanation:

y = -x + 6

y = -3x - 4

(-5,11)

x = -5

y = 11

y = -x + 6

(11) = -(-5) + 6

11 = 5 + 6

11 = 11

y = -3x - 4

(11) = -3(-5) - 4

11 = 15 - 4

11 = 11

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°
