2x+y=82x+y=8
If we double each side of the second equation, 2x+y=82x+y=8, we have 4x+2y=164x+2y=16. Explain why the same pair that is the solution to the system is also a solution to this new equation.
If needed, you can support your explanation with hanger diagrams (upload a picture), or by inventing a situation that the equations represent.
If we add the two equations in the original system, we have 6x+7y=326x+7y=32. Explain why the same (x, y) pair is also a solution to this equation.
Again, you can support your explanation with diagrams or a situation, if needed.
The equations are a system of linear equations. Modifying them through multiplication or addition while keeping both sides balanced doesn't change the solution. Any pair (x,y) satisfying one equation will satisfy the others.
In mathematics, these equations are a system of linear equations. This is essentially a set of two or more equations, with a common set of variables. The same pair (x, y) are the solutions for all equations, as the second equation is a simplified, scalar multiple of the first.
So, for the first original equation (4x + 6y = 24), and the modified one (4x + 2y=16) which is the second equation of the system doubled, we can see that the multiplier is the same for both the 'x' and 'y' on the left side, and the right side of the equation. Therefore, if a pair (x,y) has been found to satisfy the first equation, it will also work for the second, as essentially, the equations are equivalent.
Similarly, adding the original system of equations, we get 6x + 7y = 32. This also has the same solution set, just expressed differently. As long as you're performing the same operation (like doubling, adding etc.) to each side of the equations, the balance remains constant, retaining the same solution.

because you don't make sentence
Question 4 options:
18x^4 – 12x^2 = 6x(3x^3 – 2x)
12x^5 + 8x^3 = 2x^3(6x^2 + 4)
20x^3 + 12x^2 = 4x^2(5x + 3)
24x^6 – 18x^5 = 6x^5(4x – 3)
2) y= -1/2x+3
3) y= -1/2x-3
4) y= -2x-3
Please explain why the answer is what it is.
Answer: Yes.
Step-by-step explanation:
First, we will solve the given equation for y.
Given:
-6 + 4y < 6
Add 6 to both sides of the equation:
4y < 12
Divide both sides of the equation by 4:
y < 3
Then, we will confirm if the given coordinate point is within this range. We find that this is a solution.
y < 3
-3 < 3 ✓
a. x = 8, y = 17
b. x = 6, y = 8
c. x = 8, y = 10
d. x = 8, y = 6
