Answer: (no promises this is exactly right)
-2r+6
Step-by-step explanation:
−3r+9+r+−3
=
(−3r+r)+(9+−3)
=
−2r+6
If -0.14 is changed to 2, the graph would become a positive graph, or it would be steeper, because it has a positive slope
The equation of the graph is given as:

The above equation is a linear equation, which is represented as:

Where m represents the slope of the linear equation.
By comparison, we have:

i.e. the slope of the equation
is -0.14
When -0.14 is replaced with 2, the equation becomes

And the slope of the new equation
is

2 is greater than -0.14, and 2 is positive.
This means that the graph would become a positive graph, or it would be steeper, because it has a positive slope

Answer: 79 seconds.
Step-by-step explanation:1) we have to calculate the lenght of the baseball field.
perimeter of the baseball field=2(radius)+lenght of a semicircle.
2(radius)=2(175 ft)=350 ft
lenght of a semicircle=40% of a circumference=(40/100)(2πr)
Perimeter of the baseball field=2(175 ft) + (40/100)(2π175 ft)=
=350 ft + 140π ft=350 ft + 439.82 ft=789.82 ft,
2)Now, we calculate the amounts of time that it takes you to ruan arount the baseball field.
10 ft------------------------1 second
789,82 ft----------------- x
x=(789.82 ft * 1 second) / 10 ft=78.98 s≈79 s
