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 .

kozerog [31]
Area of rectangle = l × b = height × base = bh
Area of traingle = ½bh'
Area of rectangle = Area of triangle (given)
bh = ½bh'
h' = 2h
It means that the height of the given triangle is double the height of the rectangle.

For a direct variation describe how the constant of variation affects whether y increases or decreases as x increases
Goryan [66]
Direct variation is of the form: y=kx  (inverse variation is of the form y=k/x)

Assuming that k is positive :)

y increases as x increases and y decreases as x decreases.  There is a direct ratio that is described by k.  k=y/x.

Math question <br> -3y+12 = -48
svetoff [14.1K]

Answer:

y = 20

Step-by-step explanation:

-3y+12 = -48 .        -12 from both sides

-3y = -60 .              ÷3 on both sides

y = 20
