The answer is Y=11, X=-1
Here's my work:

x=-12+y

-6(-12+y)+2y=28

6*12= 72

72 -6y +2y=28 (now we combine like-terms)

72-4y=28 (now divide by -4)

-18+y=-7 (add 18 to both sides)

y=11

next part we find x:

x=-12+(11)
x=-1

    So Sine must be Option D
  2. Cos x = Adj/Hyp
    So Cosine must be Option C
  3. Tan x = Opp/Adj

A polar bear swims 390 meters at a constant rate in 150 seconds. what is the speed of the polar bear?
worty [1.4K]
The answer is 2.6 m/s

The speed (v) is distance (d) through time (t).
v = d/t

We know:
d = 390 m
t = 150 s

v = d/t
v = 390 m / 150s
v = = 2.6 m/s

Pre calculus law of sines
lakkis [162]

Answer:

AB = 6.5

Step-by-step explanation:

C = 59°

AC = 7

CD = 6

AB = ?

Apply the Law of Cosines, which is AB² = AC² + CD² - 2(AC)(CD)*Cos(C)

AB² = 7² + 6² - 2(7)(6)*Cos(59)

AB² = 85 - 43.26

AB² = 41.74

AB = √41.74

AB = 6.5 (nearest tenth)
