Convert the equation y= -4x + 2/3 into general form equation and find t the values of A,B and C.

alukav5142 [94]

Answer:

Standard form: $12x+3y-2=0$

A = 12, B = 3 and C = -2

Step-by-step explanation:

Given:

The equation:

$y= -4x + \dfrac{2}3$

To find:

The standard form of given equation and find A, B and C.

Solution:

First of all, let us write the standard form of an equation.

Standard form of an equation is represented as:

$Ax+By+C=0$

A is the coefficient of x and can be positive or negative.

B is the coefficient of y and can be positive or negative.

C can also be positive or negative.

Now, let us consider the given equation:

$y= -4x + \dfrac{2}3$

Multiplying the whole equation with 3 first:

$3 \times y= 3 \times -4x + 3 \times \dfrac{2}3\\\Rightarrow 3y=-12x+2$

Now, let us take all the terms on one side:

$\Rightarrow 3y+12x-2=0\\\Rightarrow 12x+3y-2=0$

Now, let us compare with $Ax+By+C=0$ .

So, A = 12, B = 3 and C = -2

It takes 2 ounces of paint to completely cover all 6 sides of a rectangular prism box

xxMikexx [17]

Answer:

120 cups of sugar

8 ounces of paint

Step-by-step explanation:

Given that :

To cover all sides of the rectangular prism with paint, that is the surface area.

The amount of sugar held by the prism is function of its volume.

Hence, doubling the dimension :

The surface area, in unit² is a obtained by

Initial paint required * 2^2

2 * 2² = 2 * 4 = 8 ounces of paint.

For sugar :

It has to do with volume, unit³

Initial * double³

15 * 2³

15 * (8) = 120 cups of sugar
