Answer:

Step-by-step explanation:
From the graph,
The initial red incline is a straight line passing through the origin.
So, a straight line passing through the origin is of the form:

Where, 'm' is the slope.
Now, the slope of a given as the change in y value to change in x value.
Consider the two end points of the red line (0, 0) and (4, 6).
The slope with two points
on the line is given as:

Plug in
. Therefore, slope is:

Hence, the equation of the initial red incline is:

Triangle RSQ:
30:25:15
Final simplified answer: 2.8:2.8:2.8
Scale factor of 2.8
Step-by-step explanation:
Each triangle's sides are a part of the ratio, then you divide each side by the corresponding one (84 by 30, and 70 by 25) to get your scale factor.
Answer:
-3
Step-by-step explanation:
-11b + 7 = 40
Subtract both sides by 7.
-11b = 33
Divide both sides by -11.
b = -3
