See photo for question...sorry.

The graph represents the gallons of water in a water tank with respect to the number of hours since it was completely filled

Astudent draws two parabolas on graph paper. both parabolas cross the x-axis at (-4, 0) and (6,0). the y-intercept of thefirst parabola is (0, –12). the y-intercept of the second parabola is (0-24). what is the positive difference between the avalues for the two functions that describe the parabolas? write your answer as a decimal rounded to the nearest tenth.

Complete the solution of the equation. find the value of y when x equals to 1 9x-5y=29
