Tresset [83]3 years ago

<span><span>Solve equation 2 for x:
2x - 2y = -12
2x = 2y -12
x = y - 6
.
Using the above definition of x, we plug it in to equation 1 and solve for y:
2x + 5y = 2
2(y - 6) + 5y = 2

2y - 12 + 5y = 2
7y - 12 = 2
7y = 14
y = 2
.
Plug the above back into equation 2 and solve for x:
2x - 2y = -12
2x - 2(2) = -12
2x - 4 = -12
2x = -8
x = -4
.
Solution: 
x = -4
y = 2</span></span>

"Increasing" and "decreasing" are references to what the y-values do when the x-values increase.  

Attached is a copy of all four tables, marked with whether the y-values increased or decreased on each step (and it also shows how much that increase or decrease was.

The only table that does this is the top right table in the attachment, which is your second table.

A = 10.5%

B = 28.9%

C = 39.5%

D = 18.4%

F = 2.6%

Step-by-step explanation:

Add all the frequencies together = 38

  • 4/38 × 100 = 10.5%
  • 11/38 × 100 = 28.9%
  • 15/38 × 100 = 39.5%
  • 7/38 × 100 = 18.4%
  • 1/38 × 100 = 2.6%

10.5 + 28.9 + 39.5 + 18.4 + 2.6 = 100%
