QUADRATIC FORMULA: You are throwing a football on the field. The path of the ball modeled by the equation h(t) = -.51(t+1.02)(t-87) where h is the height above the ground in feet and time in seconds after the ball is thrown. Answer these questions : How high does the ball travel? How long does it take the ball to hit the ground? How high above the ground is the ball when you throw it? Your friend catches the ball when it is 3.2 feet in the air. How long after you throw the ball does your friend catch it?

so firstly, we need to isolate the y variables to be able to solve these inequalities. firstly, add 0.5x on both sides of the first inequality and subtract 1.5x on both sides of the second inequality:

now since the slope is positive for the first inequality, this means that the line going upwards belongs to the first inequality, and the line going downwards belongs to the second inequality.

next, since y ≥ in the first inequality, this means that the shaded region will be above the first inequality's line, thus shading regions a and b.

next, since y ≤ in the second inequality, this means that the shaded region is going to be below this line, thus shading regions a and c.

since both lines shade region a, this means that region a is the solution.
