we are given

To find x-intercept means we have to find zeros
and for finding zeros , we will use quadratic formula
and we have it has two x-intercepts
so, it's discriminant must be greater than 0
so, we will find discriminant

now, we can compare with


and then we can find a , b and c

now, we can find D


It has two x-intercepts
so,

now, we can solve for m

Depth: 7/2 feet
Rate: 5/4 feet per hour
Time = depth / rate of filling
Time = 7/2 / 5/4
Time = 14/5
Time = 2 4/5 hours
No it does not. Any function that has any of the same X vaules (The line going up left to right) is not a function.
Adding integers with different signs is just like adding or subtracting. First you just have to add all negative integers and also add all positive. After that positive intergers will be deducted by the sum of negative integers
