Drag the tiles to the correct boxes to complete the pairs.

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.

Julio's father is 4 times as old as Julio. The sum of their ages is no less than 55.

Valentin [98]

Julio is x years old and his father is y years old:
y = 4 x
x + y ≥ 55
x + 4 x ≥ 55
An inequality is:
5 x ≥ 55
x ≥ 55 : 5
x ≥ 11
The youngest age Julio can be is 11.
