Answer:

The answer is C. M might cause N, N might cause M

Step-by-step explanation:

The slope of the line produced by Lisa’s graphing calculator has nothing to do with whether m causes n, n causes m, or neither (One exception to this would be if the slope were 0. This would imply no correlation, and thus, no causation.) Since the correlation coefficient (r) is 0.962 in both cases, a correlation probably exists between m and n. However, correlation does not imply causation, nor does it imply a lack of causation. Therefore, the conclusion of Lisa’s that is the most valid is m might cause n, or n might cause m.

Pilar says that two linear systems below have the same solution. (see picture) Is she correct? Explain.

The first set:

3x + 2y = 2 ---1)
5x + 4y = 6 ---2)

From 1), multiply all by 2, 6x + 4y = 4 ---3)

3) - 2),

6x + 4y - (5x + 4y) = 6 - 4
6x + 4y - 5x - 4y = 2
x = 2

Sub in x = 2 into 1),

3(2) + 2y = 2
2y = -4
y = -2

(2 , -2)

The second set:

3x + 2y = 2 ---1)
11x + 8y = 10 ---2)

From 1), multiply all by 4, 12x + 8y = 8 ---3)

3) - 2),

12x + 8y - (11x + 8y) = 8 - 10
12x + 8y - 11x - 8y = -2
x = -2

From this x value alone, we can tell that these two linear systems do NOT have the same solution as they meet at different coordinates.

Hope this helped! Ask me if there's any working from here that you don't understand! :)
