Drag the tiles to the correct boxes to complete the pairs.
padilas [110]

Answer:

One Solution:

-3x+y=7\\21x+4y=-8

Infinitely Many Solution:

31x-y=4\\61x-2y=8

No Solution:

y=-4r+5\\y=-4r+1

Step-by-step explanation:

System 1

-3x+y=7\\21x+4y=-8

Eq(1)\times7+Eq(2)\\11y=41\\y=\frac{41}{11} \\\\From\ Eq\ 1\\-3x+\frac{41}{11} =7\\-3x=7-\frac{41}{11}\\-3x=\frac{36}{11}\\x=\frac{-12}{11}

Hence only one solution (-\frac{12}{11},\frac{41}{11})

System 2

31x-y=4\\61x-2y=8

Both represents the same line. Hence these have infinitely many solutions.

System 3

y=-4r+5\\y=-4r+1

Compare both the lines with y=mx+b, where m is the slope.

m=-4 for both the lines.

Hence these two lines are parallel that means there does not exists any point of intersection

So this system will not have any solution.
