Variable y varies directly with variable x. If x = 12, then y = 3. What is the value of y
Monica [59]

Answer:

<h2>y = 2</h2>

Step-by-step explanation:

To find the value of y when x = 8 we must first find the relationship between the two variables.

The statement

y varies directly with variable x is written as

y = kx

where k is the constant of proportionality

when

x = 12

y = 3

Substitute the values into the above formula and solve for k

That's

3 = 12k

Divide both sides by 12

k =  \frac{1}{4}

So the formula for the variation is

y =  \frac{1}{4} x

when

x = 8

y =  \frac{1}{4}  \times 8

we have the final answer as

<h3>y = 2</h3>

Hope this helps you

Help me w this multiple choice!
olga2289 [7]

Answer:

D

Step-by-step explanation:

\sin(30)  =  \frac{n}{ \frac{10 \sqrt{3} }{3} }   \\ 0.5 =  \frac{n}{5.77} \\ n = 2.88 =  \frac{5 \sqrt{3} }{3}

\cos(30)  =  \frac{m}{ \frac{10 \sqrt{3} }{3} }  \\ 0.866 =  \frac{m}{5.77}  \\ m = 5
