How many solutions does this linear system have? y = 2x – 5 –8x – 4y = –20

Mathematics

6 0

Answer:

2 solutions.

Step-by-step explanation:

Rearrange the second equation:

-8x - 4y = -20

-4y = 8x - 20

Divide through by -4:

y = -2x + 5

and our first equation is

y =  2x - 5

Subtracting the 2 equations

0 = -2x -2x + 5 -(-5)

0 = -4x + 10

x = 5/2

and y = 2(5/2) - 5 =  0.

2 solutions.

So try and recognize the pattern. For level 1, you have 1 box and 12 cans. In 2, you have 3 boxes and 36 cans. 12/1 is 12, 36/3 is 12 and so on. The # of boxes times 12 is the number of cans. The # of boxes in the display is equal to the total number of boxes in each level. Level 5 will mean 1+2+3+4+5=15. Level 6 is 1+2+3+4+5+6=21. So if 6 has 21 display boxes, we can do 21*12 and you will get 252. Your answer is E, 252 cans.
