Determine if the following system of equations has no solutions, infinitely many
DochEvi [55]

Answer:

There is one solution

Step-by-step explanation:

2x + y = -1

8x + 3y = -2

Multiply the first equation by -4

-8x -4y = 4

Then add the equations together to eliminate x

-8x -4y = 4

8x + 3y = -2

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

   -y = 2

Multiply by -1

y =-2

Now find x

2x+y =-1

2x+-2 =-1

Add 2 to each side

2x-2+2=-1+2

2x=1

Divide by 2

x = 1/2

Explain pls and thanks

Starting more simply, if we wanted to know how many students like pink in general, that's 68/100. We could do that for each single category and the fractions would add together to equal 1. Now say we wanted to know something about that 68/100 people. That 68 is our new 100%, or another way of looking at it is if we take however many people like pink and don't like black and those that do like black, they will equal 68/68.

The number of people that like pink but don't like black is 41/68 and those that like pink and black are 27/68. 27+41=68 For the question of your problem it is asking about those that do not like pink which you can tell from the table or use from my saying 68/100 like pink is 32. Now you can split that into those that do or don't like black, and the two results will equal 32/32.

Given:

The area model.

The area of the shape is 82 square units.

To find:

The correct equation for the given situation.

Solution:

We know that, area of a rectangle is

Area=Length \times Width

The figure is divided into 3 rectangles. Using this formula, the area of each rectangle is

A_1=(x)\times (3x)=3x^2

A_2=(x)\times (4)=4x

A_3=(3)\times (3x)=9x

Now, the total area is equation to 82 square units.

A_1+A_2+A_3=82

3x^2+4x+9x=82

3x^2+13x=82

Since the required equation is 3x^2+13x=82, therefore, the correct option is C.
