Answer: so F(m) because F dollars for every mph over the speed limit
so 40 dollar speeding fine so +40 
10 dollars for every mile over and m=miles over so put them all toghether and get
F(m)=10m+40


1.
so if you were going 78 mph
to find the mph over you would do 78-70=8mph over so put in 8 for m and get
F(8)=10(8)+40=80+40=$120 fine for going at 78 mph

Write the equation of the line that passes through (2, 3) and is parallel to the line 12x – 5y = 2.

Answers

         12x - 5y = 2
12x - 12x - 5y = -12x + 2
                 -5y = -12x + 2
                  -5          -5
                    y = 2.4x - 0.4
               y - 3 = 2.4(x - 3)
               y - 3 = 2.4(x) - 2.4(3)
               y - 3 = 2.4x - 7.2
                 + 3           + 3
                    y = 2.4x - 4.2

Answer:

A
