You can simply multiply all the combinations of 3,5, and 7 in pairs:

1) 3 * 5 = 15

2) 3 * 7 = 21

3) 5 * 7 = 35

Don't forget the numbers multiplied to itself:

4) 3 * 3 = 9

5) 5 * 5 = 25

6) 7 * 7 = 49

Tell whether x and y show direct variation. Explain your reasoning. x=y+2

Mashutka [201]

Answer:

It does not show variation

Step-by-step explanation:

Given

$x = y + 2$

Required

Determine if there's direct variation between x and y

The general form of direct variation is:

$y = kx$

Make y the subject of formula in the given parameters;

$x = y + 2$

$y = x - 2$

Compare $y = x - 2$ to $y = kx$

<em>Since they are not of the same form, then the given equation do not show direct variation</em>

Please help me I honestly have zero clue how to answer this question

Iteru [2.4K]

Step-by-step explanation:

$n = 3 \times 5 {}^{2} \times {x}^{3}$

Square both sides of the equation.

${n}^{2} = (3 {}^{2} \times 5 {}^{4} \times {x}^{6} )$

$5 {n}^{2} = 5(3 {}^{2} \times {5}^{4} \times {x}^{6} )$
