An Air Force plane left Rome seven hours
before a cargo plane. The planes flew in
opposite directions. The cargo plane flew
at 350 mph for two hours. After this time
the planes were 4480 mi. apart. What was
the Air Force plane's speed?

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°

both graphs increase on their domain

neither graph has a y-intercept

step-by-step explanation:

the following points can be visualized easily from the graph
