Convert the equation y= -4x + 2/3 into general form equation and find t the values of A,B and C.
alukav5142 [94]

Answer:

<em>Standard form: </em>12x+3y-2=0<em></em>

<em>A = 12, B = 3 and C = -2</em>

<em></em>

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, <em>A = 12, B = 3 and C = -2</em>

54 and 67 use numbers and operations to write each phrase as an expression
arsen [322]

The phrases you would like to be written as expressions are not listed. I would nevertheless, explain how to write phrases as expressions so that the same approach could be applied to you own question.

Phrases are dynamic, depending on the problem. They do not necessarily take a particular form.

The constant thing about phrases is the operators connecting the words in the phrases. Theses operators are:

Addition (+), Subtraction (-), Division (÷), and Multiplication (×).

In word problems, it is a matter of interpretation, these operators can be written in many ways.

ADDITION

plus

the sum of

increase

grow

add

profit

And so on.

SUBTRACTION

minus

loss

decrease

reduce

subtract

And so on

MULTIPLICATION

times

multiply

triple

And so on

DIVISION

split

share

divide

distribute

And so on.

Examples

(1) 56 is added to a number to give 100

Interpretation: x + 56 = 100

(2)The difference between Mr. A and Mr. B is 5

Interpretation: A - B = 5

(3) This load (L1) is three times heavier than that one (L2)

Interpretation: L1 = 3L2

(4) Share this orange (P) equally between the three children

Interpretation: P/3
