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.

Elizabeth made an English muffin pizza using 1/4 cup of cheese and 3/8 cup of sausage. How many cups of toppings did she use?

Sonbull [250]

Answer: The answer is $\dfrac{5}{8}~\textup{cups}.$

Step-by-step explanation: Given that Elizabeth made an English muffin pizza by adding the following quantities of cheese and sausage..

Cups of cheese used by Elizabeth is given by

$C_c=\dfrac{1}{4}~\textup{cups}.$

And cups of sausage used by Elizabeth is given by

$C_s=\dfrac{3}{8}~\textup{cups}.$

Therefore, total number of cups of toppings used by Elizabeth is

$C=C_c+C_s=\dfrac{1}{4}+\dfrac{3}{8}=\dfrac{5}{8}~\textup{cups}.$

Thus, the number cups of toppings used is $\dfrac{5}{8}~\textup{cups}.$
