using the associative property, 9 + (6 - 3) = (9 + 6) + 3. is 9 - (6 - 3) equal to (9 - 6) - 3? explain.

goldfiish [28.3K]

No because it only works with addition and multiplication

9+(-6-3)=(9-6)-3 is true tho

9-(6-3)=9-(3)=6
(9-6)-3=(3)-3=0
so not equivilent

Answer:

The answer is

$p = \frac{ - 3}{1000} n + 97$

Step-by-step explanation:

We have the points (2000,91) and (5000,82)

Then

$m = \frac{91 - 82}{2000 - 5000} = \frac{ - 3}{1000} \\ to \: find \: the \: b \\ 91 = \frac{ - 3}{1000} \times 2000 + b \\ b = 97 \\ then \: the \: equation \: is \: \\ p = \frac{ - 3}{1000} n + 97$
