Answer:
d-2 < -1
Step-by-step explanation:
The complete question in the attached figure
we know that
the range is the y-value of the function
so
the lowest y-value on this graph is y = -2.
the answer is
y=-2
The ball describes a parabola, as you can see in the attached picture. So, the point where the ball strike the ground is the point where the parabola meets the x axis. In fact, the x-axis is the set of points where y=0, which means that the ball has height 0 or -again- it hits the ground.
So, we have to set y=0 in our equation and look for the positive solution. We have

And the positive solution is

So that's the distance from the child where the ball strikes the ground.
When n=\frac{9}{4}n=49, the original equation -4|8-5n|=13−4∣8−5n∣=13 does not hold true.
We will drop n=\frac{9}{4}n=49 from the solution set

chance of getting a red marble is 8/50
8/50 = 80/500
Answer is 80
