A ball is thrown downward with an initial velocity of 35 meters per second from a cliff that is 130 meters high. The height of the ball is given by the quadratic equation: h=-4.9 t^{2}[/tex]-35t+160 where h is in meters and t is the time in seconds since the ball was thrown. After how many seconds will the height of the ball be 30 meters? WILL GIVE BRAINLIEST!

step-by-step explanation:

from this example, we can see that subtracting with integers is the same as adding the opposite. we can solve using a number line or by using the saying "keep, change, change" to us solve. it is important to remember that we can subtract a negative and end up with a larger number than we started with.
