Hello,

What is the value of the x variable in the solution to the following system of equations?

3x + 2y = 8

2x + 3y = 2

Lets use 4:

3(4) + 2y = 8

12 + 2y = 8

12 + 2(-2) = 8

12 + -4 = 8

--------------------

2x + 3y = 2

2(4) + 3y = 2

8 + 3y = 2

8 + 3(-2) = 2

8 + (-6) = 2

So option A is true! (But remember that there can be more than one solution.)

Lets use -2:

3x + 2y = 8

3(-2) + 2y = 8

-6 + 2y = 8

-6 + 2(7) = 8

-6 + 14 = 8

-------------------

2x + 3y = 2

2(-2) + 3y = 2

-4 + 3y = 2

-4 + 3(2) = 2

-4 + 6 = 2

So option B is also true! (But again there can be more than one solution)

Answer:

So we have proved that there can be more than 1 solution for these set of equations. So the best answer is C: x can be any number as there are infinitely many solutions to this system.

Write an expression that represents the perimeter of the triangle.

uysha [10]

Answer:

(3m - 2) + (2m + 7) + (5m - 3)

Step-by-step explanation:

Perimeter is found by combining all side measurements together to find the total measurement. In this case, combine the sides:

(3m - 2) + (2m + 7) + (5m - 3) is your answer.

If you need a simplified expression, simply combine all the like terms together. Like terms are terms with the same as well as same amount of variables:

(3m + 2m + 5m) + (7 - 2 - 3)

(10m) + (2)

10m + 2 is your answer.

What is the measure of

Anastasy [175]

Hey!!!

here's your answer

X+128=180( sum of angle in straight line)

or,X=180-128

X=52 degree.

So the value of X is 52 degree.

Hope it helps...

Good luck on your assignment

3+×/2=10 Is ×/2=7 And does ×=14

adoni [48]

$3+\dfrac{x}{2}=10\qquad|\text{subtract 3 from both sides}\\\\\dfrac{x}{2}=7\qquad|\text{multiply both sides by 2}\\\\\boxed{x=14}$

Which represents the solution of the graphed system of equations, y=x^2-2x and y=-2x-1

elena55 [62]

Answer:

x = √(-1) = i

Since the value of √(-1) is not real.

The system has no real solution.

Step-by-step explanation:

The solution to the system of equations is at the point where they intercept each other.

y1 = y2

For the given equation;

y=x^2-2x and y=-2x-1

To get the where they intercept, we will equal both equations;

y=x^2-2x = -2x-1

x^2 - 2x = -2x - 1

x^2 - 2x + 2x + 1 =0

x^2 +1 = 0

x^2 = -1

x = √(-1) = i

Since the value of √(-1) is not real.

The system has no real solution.
