Question

Choose the correct description of the graph of the compound inequality x − 3 < −9 or x + 5 greater than or equal to 10.

A. A number line with an open circle on −6, shading to the left, and a closed circle on 5, shading to the right
B.A number line with a closed circle on −6, shading to the left, and an open circle on 5, shading to the right
C. A number line with an open circle on −6, a closed circle on 5, and shading in between
D. A number line with a closed circle on −6, an open circle on 5, and shading in between

This is the answer Solution Set: x, (-∞, 12) or (5, ∞). So which answer choice does this corresponds with above??

Answer 1

x - 3 < -9
x < -9 + 3
x < -6

x + 5 > = 10
x > = 10 - 5
x > = 5

open circle on -6, closed circle on 5, shading in between
