Answer:
1) Solve for the first variable in one of the equations, then substitute the result into the other equation.
x=6−3y
3) Solve for the first variable in one of the equations, then substitute the result into the other equation.
Point Form: (3,−5)
Equation Form: x = 3,y = −5
Answer:
For the Sean one it should be 12y=12 then you would divide 12 by 12 to get y=1
For the one about the hair: No, 40 months isn’t reasonable.
For the one about the graph, I am not sure, sorry!
Step-by-step explanation:
Hair: For Shellie: 40*3 = 120 cm in 40 months
For Carley: 40*2 = 80cm in 40 months
Next we add the amount of hair they have already to the amount of centimeters would grow.
Shellie: 120+10 = 130cm
Carley: 80+20 = 100cm
So if the girls wanted to cut their hair at the exact length, 40 months isn’t a reasonable solution.
Here is how I think the graph will look, sorry if it is incorrect I am only good at solving not graphs
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.
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.

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)
AlternativelySolving 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)

Answer:
For every 5 students scoring in the 60s, there were 2 students scoring in the 70s.
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.

1.25+7.5=y graph the equation
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

Answer:
(2,0) or 2
Step-by-step explanation:
The x-intercept is the point where the line intercepts or goes through the x-axis. The x-axis is the horizontal line that is labeled x.
Another way to find the x-intercept is to find the x value when the y value or f(x) equals zero.
