(a) I have the line plot attached
(b) Purple mean: 30
Red mean: 36
Purple median: 30
Red median: 36
I'm sorry, that is as much as I can help with, I really am sorry.
Solve the following system using elimination:
{7 x + 2 y = -19 | (equation 1)
{2 y - x = 21 | (equation 2)
Add 1/7 × (equation 1) to equation 2:
{7 x + 2 y = -19 | (equation 1)
{0 x+(16 y)/7 = 128/7 | (equation 2)
Multiply equation 2 by 7/16:
{7 x + 2 y = -19 | (equation 1)
{0 x+y = 8 | (equation 2)
Subtract 2 × (equation 2) from equation 1:
{7 x+0 y = -35 | (equation 1)
{0 x+y = 8 | (equation 2)
Divide equation 1 by 7:
{x+0 y = -5 | (equation 1)
{0 x+y = 8 | (equation 2)
Collect results:
Answer: {x = -5, y = 8
Answer:
16
Step-by-step explanation:
First, simplify by finding the absolute values:
2|-9| - |-2|
2(9) - (2)
Then, simplify this by multiplying 2 and 9:
18 - 2
= 16
So, the answer is 16
