Step-by-step explanation:
Now, <u>According to our assumption we can set up an equation :</u>
➵ (180 - x) - 3(90 - x) = 10
➵ 180 - x - 270 + 3x = 10
➵ 2x - 270 = 10 - 180
➵ 2x - 270 = -170
➵ 2x = -170 + 270
➵ 2x = 100
➵ x = 100/2
➵ x = 50
Answer:
The rate of change of the equation x=9 is 9.
x=30
The slope of the line between two points can be found with the following equation:
Plugging in the points and from the problem statement, we get the following:
0.46%
I think this is right :w
