Answer:

The constant of proportionality is option D i.e 5.

Step-by-step explanation:

Variation:

Variation problems involve fairly simple relationships or formulas, involving one variable being equal to one term. There are two types of variation i.e.

  1. Direct variation
  2. Inverse variation

Direct Variation:

Mathematical relationship between two variables that can be expressed by an equation in which one variable is equal to a constant times the other.

Example y=kx

where, k  is constant of proportionality.

The above given example is of Direct Variation

∴ y = 5 x

∴ k = 5 = constant of proportionality.

Inverse Variation:

Mathematical relationship between two variables which can be expressed by an equation in which the product of two variables is equal to a constant.

Example yx=k

where, k  is constant of proportionality.

Answer:

5

Step-by-step explanation:

In Y = 5X .

Y is proportional to X.

Now, When We will increase X by 1 , Y will increase by 5,

As we can see from the equation

So Constant of proportionality is 5.

{Y = 5X

\frac{Y}{X} = 5}

Constant of proportionality is the ratio between two quantities which are directly proportional to each other .

1. <u>Correct</u>

2. <u>Incorrect</u>, answer is x ≤ -4.25   This is because the line goes to the left so it is less than or equal to.

3. <u>Incorrect</u>, the answer is the choice at the top, because it is greater than, it goes to the right and has a empty circle.

4. <u>Incorrect</u>, the answer is the choice at the bottom cuz it is greater than or equal to so the line goes to the right and the circle is filled in.

Hope that helps u!!

Solve the following system of equations algebraically<br> 3x-y=0<br> 5x+2y=22
Lyrx [107]

3x  -  y  = 0     ⇒   2(3x  -  y  = 0 )   ⇒   6x - 2y = 0

5x + 2y = 22  ⇒   1(5x + 2y = 22)   ⇒   <u>5x + 2y</u> = <u>22 </u>

                                                              11x         = 22

                                                                x          = 2

3x  -  y  = 0   ⇒   3(2) - y = 0   ⇒   6 - y = 0   ⇒   6 = y

Answer: x=2, y=6
