Answer:

x and y do not show direct variation.

Step-by-step explanation:

The formula for direct variation is

y = kx Divide each side by y

k = y/x

k should have the same value for every point except, of course, (0,0)

For the first point,

k = 2/(-1) = -2

For the third point,

k = 2/1 = 2

The values of k are different, so x and y <em>do not</em> show direct variation.

3√6+4√6 is equal to

Oksi-84 [34.3K]

Answer:

$7\sqrt{6}$

Step-by-step explanation:

You can only add radicals if the value inside the square root symbol is the exact same, therefore, this one is 6. To find the sum, we can add the values outside the square root symbol (3 and 4) to get our new radical.

We can also check this.

$3\sqrt{6} = \sqrt{9*6} = \sqrt{54}$ ≈ 7.35

$4\sqrt{6} = \sqrt{16*6} = \sqrt{96}$ ≈ 9.8

$7\sqrt{6} = \sqrt{49*6} = \sqrt{294}$ ≈ 17.15

7.35+9.8 = 17.15

Hope this helped!

may painted 4 out of 8 equal parts of a poster board blue . Jared painted 2 out of 4 equal parts of a same size poster board red

fenix001 [56]

Given:
May painted 4 out of 8 equal parts of a poster board is blue.
Jared painted 2 out of 4 equal parts of the same sized poster board red.

May: 4/8 = 1/2 of the poster board.
Jared: 2/4 = 1/2 of the poster board.

The fractions are equal. Since the poster board is of the same size, both May and Jared painted equal parts which is 1/2 of the poster board.

The 8 and 4 only indicate the number of equal parts that are drawn on the poster board.
