1). Linear Combination (SHOW WORK)
Georgia [21]

Answer:

Part 1) The solution of the system of equations is (2,-5)

Part 2) The solution of the system of equations is (2,4)

Step-by-step explanation:

Part 1) Linear combination

we have

3x+2y=-4 -----> equation A

4x-y=13 -----> equation B

Multiply equation B by 2 both sides

2(4x-y)=2*13

8x-2y=26 -----> equation C

Adds equation A and equation C

3x+2y=-4\\8x-2y=26\\-------\\3x+8x=-4+26\\11x=22\\x=2

Find the value of y

3(2)+2y=-4

2y=-4-6

2y=-10

y=-5

The solution of the system of equations is (2,-5)

Part 2) By graph

y=(1/2)x+3 -----> equation A

-3x+y=-2 -----> equation B

we know that

The solution of the system of equations is the intersection point both graphs

Using a graphing tool

The intersection point is (2,4)

therefore

The solution of the system of equations is the point (2,4)

Mariko has an 80: 1 scale drawing of the floor plan of her house. On the floor plan
Ivan

Answer:

16,771.56 square feet.

Step-by-step explanation:

In order to get to the result we will need to use the scale and the numbers that are provided of the dimensions of the room.

The dimensions of the room on the floor plan are 17.8 inches by 21.2 inches. We first need to multiply these numbers with the scale:

17.8 x 80 = 1,424

21.2 x 80 = 1,696

Now that we got the real measures we need to multiply these two values in order to get to a result as in how many square inches is the room:

1,424 x 1696 = 2,425,104

Now we need to convert the square inches into square feet to get to the final result:

1 ft² = 144 in²

2,425,104 / 144 = 16,771.56

So we have a result of 16,771.56 square feet.
