2) Graph the quadratic function to identify the maximum or minimum of
the function.

A) min{x^2 + 4x - 5} = -9 at x = 2
B) max{x^2 + 4x - 5) = -9 at x = 2
C) min{x^2 + 4x - 5) = -9 at x = -2
D) max{x^2 + 4x – 5) = -9 at x = -2

1/3(x-10)=-4 solve for x with steps

Acar started driving from city a to city b, distance between which is 620 miles, at a rate of 60 mph. two hours later a truck left city b and started moving towards city a at a rate of 40 mph. what distance from city a is the point where the truck and the car will meet?

If the ratio of sum of the first m and n terms of an ap is m2 : n2 , show that the ratio of its mth and nth terms is (2m − 1) : (2n − 1).
