F(5) is like X is 5
you just do this
f(5)=-2x+1
=-2(5)+1
=-10+1
= -9

Answer: The formula to find the speed of the Ford could be F = B - 20.
Since the Ford is 20 mph slower than the Buick, all you have to do is subtract 20 from the speed of the Buick. We know the speed of the Buick, it is 65.
Therefore, the speed of the Buick is 65 - 20 or 45 mph.
Divide 400 by 10 and you will get 40. It's not hard
Payton drives 7 3/4
and Jessie drives 6 3/8
to find how much farther Payton drives subtract them
7 3/4 - 6 3/8
find the LCD or least common denominator in the fractions
3/4 = 6/8 so now you have
7 6/8 - 6 3/8
7-6 = 1
6/8 - 3/8 = 3/8
gives you 1 3/8 miles farther
