NEED HELP QUICKLY! Which system of equations has exactly one solution?

2x + y = 7

2x + y = –3

5x – 4y = 8

3x + 2y = 8

15x + 9y = 36

10x + 6y = 36

8x – 12y = 48

6x – 9y = 36

The right answer is 5x-4y=8

3x+2y=8

Step-by-step explanation:

I just guessed and I got it right... sorry I couldn’t give an explanation

according to this law, when unemployment goes up by 1%, gdp drops by 2%. in the question, unemployment rate goes from 2% to 5%, meaning unemployment goes up by 3%, so the gdp drops by 6%. thus the effect is a drop in gdp by 6%.

step-by-step explanation:

the smallest possible measurement of the width is 14 feet

step-by-step explanation:

let's assume length of parallelogram is 'l'

width of parallelogram is 'w'

the perimeter of a parallelogram must be no less than 40 feet

so, we get

we are given

length of parallelogram is 6 feet

so,

l=6

we can plug it

now, we can solve for w

subtract both sides by 12

divide both sides by 2

and we get

so,

the smallest possible measurement of the width is 14 feet
