the graph shows the height, y, in meters, of a rocket above sea level in terms of the time, t, in seconds, since it was launched. the rocket landed at sea level.
what does the x-intercept represent in this situation?
a) the time it took the rocket to return to sea level
b) the height from which the rocket was launched
c) the total distance the rocket flew while it was in flight
d) the time it took the rocket to reach the highest point in its flight

The answer is: A) The time it took to the rocket to return to sea level.

Since the graph shows the height (y) in meters of a rocket above sea level in terms of the time (x), the x-intercept is the point where the height (y) is equal to the sea level (since it was launched from the sea level).

We can see that the point has an "x" value between 10 and 11 seconds and it means that it's the time that the rocket took to reach the height from it was launche. So at that point, the "y" coordinate of the rocket will be equal to the sea level (reference point).

Hence, the correct option is A) The time it took to the rocket to return to sea level.

Have a nice day!

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.
