Answer:
You have a maximum when the parabola opens down (-x^2), and a minimum when it opens up (+x^2). In your case, it opens down because of the -. That is the special notation, the vertex of the parabola is already there.
10x8=80 dollars that day
80+30=$110
Hope this helps!! Have a good day
For this case we have the following polynomial:

Rewriting the polynomial we have:

From here, we can solve the polynomial using the quadratic equation
We have then:





Therefore, the solutions are:


Answer:
well if you add both equations it will all eliminate to 0 = -1
what is inconsistant cause there is no solution cause the statment 0 is equal to -1 is false
Step-by-step explanation:
2x + -2x = 0
-y + y = 0
-4 + 3 = -1
