The answer is C, you can solve this by sin(30)= 8/c since sine is opposite over hypotenuse and since c equals 16 there is only one possible solution

PLEASE HELP ASAP!!!
Nonamiya [84]

Answer:

Option C. Yes; y=2x

Step-by-step explanation:

we know that

A relationship between two variables, x, and y, represent a proportional variation if it can be expressed in the form k=\frac{y}{x} or y=kx

In a proportional relationship the constant of proportionality k is equal to the slope m of the line and the line passes through the origin

so

In this problem

For x=0, y=0

That means ----> the line passes through the origin

<em>Find the value of k</em>

For x=2, y=4

k=\frac{y}{x} ----> k=\frac{4}{2}=2

For x=4, y=8

k=\frac{y}{x} ----> k=\frac{8}{4}=2

The values of k are equal

therefore

The table represent a direct variation

The equation is equal to

y=2x

What is the value of f(x) = 2 • 2^x for f(–2)? Will Give brainliest answer!!!
Sedbober [7]
For f(-2), x will equal -2.

Plug the x-value into the equation:

2 \times 2^{-2}

A negative exponent means that the term turns into a fraction, with 1 as the numerator and the positive exponent as the denominator. 
Solve 2^(-2):

2^{-2} =  \frac{1}{2^{2}} =  \frac{1}{4}

Solve the problem:

2 \times \frac{1}{4} = \frac{1}{2}

f(-2) will equal 1/2.

1) -(5.8x14) = -406/5 = -81.2
2) (-1/3)(-1) = 1/3 = 0.3333333....
3) -2 + 1/4 / 1 + 1/2
-7/4 / 3/2
-1.75 / 1.5 = -7/6 = -1.166....7

What do you mean by “and”?????
Is it divided or add??
I’m only sure about the first one but tell me what and mean

Explain how you got the answer please
kykrilka [37]
-2x + 12 = 2y

Add 2x on both sides,

12 = 2y + 2x

Divide by 2 on both sides,

6 = y + x -> x + y = 6

The answer is D.
