Answer:

x ≈ 28.8°

Step-by-step explanation:

Using the sine ratio in the right triangle

sin x = \frac{opposite}{hypotenuse} = \frac{AB}{AC} = \frac{3.9}{8.1} , then

x = sin^{-1} (\frac{3.9}{8.1} ) ≈ 28.8° ( to the nearest tenth )

Which equation represents the graph?
klio [65]
The second option.

That is because
y -3 = - \frac{1}{2}(x + 1) \\ (y -3)+3 = (- \frac{1}{2} x - \frac{1}{2}) + 3 \\ y = - \frac{1}{2}x + 2 \frac{1}{2}

I will mark brainly, help me with this question please.​
Anna [14]

Step-by-step explanation:

Since x varies directly as \sqrt{y} we can write the relation as

x = k\sqrt{y}

where k is the constant of proportionality.

a) To solve for the k, we substitute the given values:

5 = k\sqrt{13} = k(13)

\Rightarrow k = \dfrac{5}{13}

b) The equation relation x and y can be written as

x = \dfrac{5}{13}\sqrt{y}

c) When y = 9,

x = \dfrac{5}{13}\sqrt{9} = \dfrac{5}{13}(3) = \dfrac{15}{13}

Solve the system Also plz show work and what you did and these two equations with x and y the x and y have to be the same in bot
Gala2k [10]
Multply both equations by 2 leaving

x + 2y = 8
x - 2y = -2

Add the equations giving

2x = 6
x = 3

Substitute 3 in the top equation

3 + 2y = 8
2y = -5
y = -2.5
