Answer:
C. (1, -3)
Step-by-step explanation:
Plug in the x to get the y in the equation. The point must fit the formula.
Plug in C. (1, -3), in which x = 1, y = -3:
(-3) = 2(1) - 5
Simplify:
(-3) = 2(1) - 5
-3 = 2 - 5
-3 = -3 (True).
C is your answer.

Answer:
x=8
Step-by-step explanation:
If it's a vertical line that means it's "sticking straight up" in a sense, so your line would go through all values of 8.

Answer:
- 33.0 m
- 26.1 mi
- 28.0 mi
- 33.0 mi
Step-by-step explanation:
In each of these Law of Sines problems, you are given side a and angles B and C and asked for side c (problems 1, 3, 4) or side b (problem 2). The solution is basically the same for each:
Find the missing angle. Find the side from ...
c = a·sin(C)/sin(A)
__
1. angle A = 180°-89°-58° = 33°
c = (18 m)sin(89°)/sin(33°) ≈ 33.0 m
__
2. angle C = 180°-13°-17° = 150°
b = (58 mi)sin(13°)/sin(150°) ≈ 26.1 mi
__
3. angle A = 180°-61°-89° = 30°
c = (16 mi)sin(61°)/sin(30°) = 28.0 mi
__
4. angle A = 180°-39°-127° = 14°
c = (10 mi)sin(127°)/sin(14°) ≈ 33.0 mi
