Answer:

Step-by-step explanation:
we have

This is the equation of the line in point slope form
where
The slope is m=1
The point is (4,8)
Convert to slope intercept form
Isolate the variable y
Adds 8 both sides

Combine like terms

Convert to function notation

9.75 * 1.2 = 11.7
24.5 * .8 = 19.6
11.7+19.6= 31.3 minutes
hope this helped :)
It would just be 14-10 each week so 14-10 14-10 14-10 and so on
Actually, the area of a triangle is a = bh/2. If a = 30 and b = 12:



So he height is 5 units
