Substitution and Elimination Methods Nathan solves the following system of equations using the elimination method. - 2x + 3y = 6 4.3 – 6y = -12 He chooses to eliminate the variable x. Which statement correctly describes his process and solution? A: Nathan multiplies - 2x + 3y = 6 by 2 and then adds the equations. He finds the result is a contradiction, so there is no solution Nathan multiplies - 2x + 3y = 6 by 2 and then subtracts the equations. He finds the result is a contradiction, so there is no solution. B: Nathan multiplies -2.x + 3y = 6 by 2 and then adds the equations. He finds the result is an identity, so there are infinitely many solutions. C: Nathan multiplies -2x + 3y = 6 by 2 and then subtracts the equations. He finds the result is an identity, so there are many infinitely many solutions.

Answers

Answer:

Nathan multiplies −2x+3y=6 by 2 and then adds the equations. He finds the result is an identity, so there are infinitely many solutions.

Step-by-step explanation:

The solution for the system of equations -

- 2x + 3y = 6

3x - 6y = -12

is (0, 2)

What is the general equation of a Straight line?

The general equation of a straight line is -

[y] = [m]x + [c]

where -

[m] is slope of line which tells the unit rate of change of [y] with respect to [x].

[c] is the y - intercept i.e. the point where the graph cuts the [y] axis.

The equation of a straight line in point slope form can be also written as-

[tex]y-y_{1}=m\left(x-x_{1}\right)[/tex]

We have the following set of equations -

- 2x + 3y = 6

3x - 6y = -12

These are the equations of a straight line. Plotting the graphs and finding the point of intersection would give us the solution. It can be seen from the graph that the solution is given by coordinate - (0,2)

Alternatively

Solving by elimination method -

- 2x + 3y = 6 ..[1]

3x - 6y = -12 ..[2]

Multiply [1] by 3 and [2] by 2 -

- 6x + 9y = 18

6x - 12y = - 24

Adding both -

- 6x + 9y + 6x - 12y = 18 - 24

-3y = - 6

y = 2

AND

- 2x + 3y = 6

-2x + 6 = 6

x = 0

Therefore, the solution for the system of equations -

- 2x + 3y = 6

3x - 6y = -12

is (0, 2)

1.25+7.5=y graph the equation

Answers

Answer:

ajsjsjskkekeoekejjdjdjskakwkkeirud

Answer:-

x= -6 y=7.5

Step-by-step explanation:

Simplifying

1.25x + 7.5 = y

Reorder the terms:

7.5 + 1.25x = y

Solving

7.5 + 1.25x = y

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '-7.5' to each side of the equation.

7.5 + -7.5 + 1.25x = -7.5 + y

Combine like terms: 7.5 + -7.5 = 0.0

0.0 + 1.25x = -7.5 + y

1.25x = -7.5 + y

Divide each side by '1.25'.

x = -6 + 0.8y

Simplifying

x = -6 + 0.8y

Step-by-step explanation:

There are 40 scorers in the 60s and 16 scorers in the 70s. These are ratios, so the ratio between the 60s and the 70s would be 40/16. This fraction can be simplified down to 5/2. This means that for every 5 students scoring in the 60s, 2 scored in the 70s.
