The slope of a straight line which is parallel to X axis is always equal to 0 (zero).

An object is launched from a platform. Its height (in meters), xxx seconds after the launch, is modeled by: h(x)=-5x^2+20x+60h(x

It takes 6 seconds for it to hit the ground.

0 = -5x²+20x+60

We can solve this by factoring. First factor out the GCF, -5:

0 = -5(x²-4x-12)

Now we want factors of -12 that sum to -4. -6(2) = -12 an -6+2 = -4:
0 = -5(x-6)(x+2)

Using the zero product property, we know that either x-6=0 or x+2=0; this gives us the answers x=6 or x=-2. Since we cannot have negative time, x=6.
