Answer:

Step-by-step explanation:
An equation of a line is given
, where m is the gradient or 
The rise indicates the change in value of y (vertical change in the graph).
The run indicates the change in value of x (horizontal change in the graph).
Let point 1 of the graph be (x,y) = (0,-34) and point 2 be (x,y) = (20,0).
Substitute point 1 into the graph to get the constant c.



∴ The equation of the line is, 
You would subtract 90% and 35% and get 55%. You subtract that by 20 and yiu will have 35% of the 90% mixture
Answer:
Angle 1 is 62°
Angle 2 is 45°
Angle 3 is 24°
Step-by-step explanation:
A. The population would be 120
You would find 20 percent of 100
To do that, you do 100× 0.2 and add that to 100
B. The population doubles
10×2= 20
20×2= 40, not 30
