Aball is thrown and it follows parabolic path at each horizontal distance x the following equation models the ball height y =0.2x^2+0.4x+3

The decibel level of sound is 50 db greater on a busy street than in a quiet room where the intensity of sound is watt/m2. the level of sound in the quiet room is db, and the intensity of sound in the busy street is watt/m2. use the formula , where is the sound level in decibels, i is the intensity of sound, and is the smallest sound intensity that can be heard by the human ear (roughly equal to watts/m2).

What are the solutions of the system? solve by graphing. y = -x^2 -6x - 7 y = 2
