D = rt
D = 50(4)
D = 200 miles
From a coordinate point of view, we have a function D(x) = 50x, where x represents time in hours.
When x = 4, y = 200.
(x, y) = (domain, range).
Our domain is 4 hours and range 200 miles.
Answer:
17. C 60°
18. D 121°
Step-by-step explanation:
The external angle is half the difference of the intercepted arcs.
17. (161° -41°)/2 = 60°
__
18. (? -59°)/2 = 31°
? = 59° +2(31°) = 121°
Answer:
undefined
Step-by-step explanation:
since both points have a y value of ten the line is vertical, making the line undefined and therefore having no slope.
The answer is b when you plug it in
