Which explains whether or not the function represents a direct variation?

s2008m [1.1K]

Answer:

The function represents a direct variation

Step-by-step explanation:

we know that

A relationship between two variables, x, and y, represent a direct variation if it can be expressed in the form $y/x=k$ or $y=kx$

In a linear direct variation the line passes through the origin and the constant of proportionality k is equal to the slope m

Let

$A(0,0)$ ------> the line passes through the origin

$B(2,10)$

Find the value of k------> substitute the value of x and y

$y/x=k$ -----> $k=10/2=5$

$C(4,20)$

Find the value of k------> substitute the value of x and y

$y/x=k$ -----> $k=20/4=5$

$D(6,30)$

Find the value of k------> substitute the value of x and y

$y/x=k$ -----> $k=30/6=5$

$E(8,40)$

Find the value of k------> substitute the value of x and y

$y/x=k$ -----> $k=40/8=5$

The value of k is equal in all the points of the table and the line passes through the origin

therefore

The function represents a direct variation

the equation of the direct variation is equal to

$f(x)=5x$

Mhanifa can you please help? Look at the picture attached. I will mark brainliest!

Answer:

Given rhombus ABCD with

m∠EAD = 67°, CE = 5, DE = 12

Properties of a rhombus:

All sides are congruent
Diagonals are perpendicular
Diagonals are angle bisectors
Diagonals bisect each other

Solution, considering the above properties

1. m∠AED = 90°, as angle between diagonals
2. m∠ADE = 90° - 67° = 23° as complementary of ∠EAD
3. m∠BAE = 67°, as ∠BAE ≅ ∠EAD
4. AE = CE = 5, as E is midpoint of AC
5. BE = DE = 12, as E is midpoint of BD
