Write the equation of a direct variation that passes through the point (-11, 13)
VMariaS [17]
<h2>Answer:</h2>

<u>A direct variation equation is of the form y = m⋅x for some constant value m</u>.

<u>For a direct variation equation passing through</u>

(x,y) = (-11,13)

13 = m × - 11

→ m = - 13/11.

so, as y = m⋅x

y = - 13/11x

<u>Hence, the direct variation equation is [C] - 13/11x</u>.

What is the value of x? Leave your answer in simplest radical form.
ad-work [718]

Answer:

sqrt 52

Step-by-step explanation:

use the pythagorean thereom

side a - 4

side b - 6

to find the hypotenuse, simply square both sides.

4² + 6²

4 x 4 = 16

6 x 6 = 36

add these two together

you should get 52.

After finding the combined side length, find the inverse operation of squared.

The inverse operation is the square root.

So find the square root of 52.

√52 = 7.21110255

round to the nearest tenth.

the answer should be 7.2

But to keep it in radical form the answer is sqrt 52
