1.) What is the best approximation of the solution to the system to the nearest integer values?
melisa1 [442]

<u>Part 1)</u> we have

5x+2y=16 ------> equation A

x+3y=12

x=12-3y ------> equation B

Substitute the equation B in equation A

5[12-3y]+2y=16

60-15y+2y=16

13y=44

y=44/13=3.38

Find the value of x

x=12-3(44/13)=1.85

the best approximation is the point (2.3)

therefore

<u>the answer Part 1) is the option C</u>

(2.3)

<u>Part 2) </u>we have

y=-x-2 ------> equation A

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

equate equation A and equation B

-x-2=3x+2

4x=-4

x=-1

Find the value of y

y=-(-1)-2=-1

the solution is the point (-1,-1)

therefore

<u>the answer Part 2) is </u>

(-1,-1)

How do u find the area?
nydimaria [60]
Act like it's a rectangle. The height is 10 because 7+3=10 and the length it 27. Multiply them for the are and you get 270 in. Then multiply 6x7=42 because that's the are of the space that is missing from the imaginary rectangle. Multiply by 2 (84 in.) because there are 2 missing spaces and subtract from 270= 186 inches is your answer.
