Mr. Raichel is in New York, about 775 miles from Chicago, and Mr. Schmit is in New Orleans, about 950 miles from Chicago. They are both going to bike home at the same time. Mr. Raichel is going to bike 105 miles a day and
Mr. Schmit is going to bike 140 miles a day.
a) When will Mr. Schmit and Mr. Raichel be the same distance away from Chicago. How far away will they
both be at the time?

105 + 140 is 245 There is your answer

Step-by-step explanation:

Your welcome I think

if the eqn of the parabola is f(x) = (x-4)(x+2), we need to mult. this out to find the coordinates of the vertex.

then f(x) = x^2 + 2x - 4x - 8, and f(x) = x^2 - 2x - 8.

one way in which you can find the vertex is to calculate x = -b / (2a).   here, that comes to

        )

x = = 1.   f(1) = 1^2 - 2(1) - 8 = - 9.   vertex is at (1, -9).

        2(1) 

find another point on the curve:   let x=0, for which y=-8.   then (0, -8) is on the curve.   plot the vertex and this point and draw a smooth parabola thru both.

hope this

x + 4/7
