Is 0.3x (4 - y) and - 1.2x - 0.3y equivalent

Mathematics

Answer:

Inconsistent

Step-by-step explanation:

We are given the equations;

0.3y=0.6x+0.3

1.2x+0.6=0.6y

Assuming we are required  to determine whether the system of equations are consistent or inconsistent  

We are going to use substitution

Making y the subject;

Equation 1: 0.3y=0.6x+0.3

Dividing both sides by 0.3

y = 2x + 1

Equation 2: 1.2x+0.6=0.6y

Dividing both sides by 0.6

y = 2x + 1

This means both equations are similar and we can't get a solution.

Therefore, the system of equations is inconsistent.

Anyone have any idea what the answer could be?

Answer:

y = -1/4x -1

Step-by-step explanation:

Mathematically, we have the slope intercept form as;

y = mx + b

where m is the slope and b is the y-intercept

from the question;

m is -1/4

So we have :

y = -1/4x + b

To get the value of b, we substitute the coordinates given and solve for b

Firstly, multiply through by 4

That will

give ;

4y = -x + 4b

4(-4) = -12 + 4b

-16 = -12 + 4b

-16 + 12 = 4b

4b = -4

b = -4/4

b = -1

So the equation in the slope intercept form is;

y = -1/4x -1
