Answer:
m=980
Step-by-step explanation:
There's a video in Google on how to do this.
The purpose of the quadratic formula is to easily obtain the x-coordinate of the vertex's location. The goal is to solve the equation by isolating x on one side of the equation, just like you would any other equation.
In step 7, take the square root of both sides. Note that you must account for the negative side of the square root, so add the +/- to the right side (not necessary for the left side because you want the x to be positive when you are finished, and you still get the same answer even if you assume the left side is negative).
Next, subtract b/2a from both sides and simplify the denominator of the root to be 2a.
Finally combine the terms to have a single denominator.
Answer:
I would say C, None of the above.
Step-by-step explanation:
Due to the fact that it says 8-1, so the number line should go to 8 down to 7.
