A) To factor a quadratic equation, standard form is the better form to use because it is easier to pull out a common factor from.
b) To graph a parabola, it is better to use vertex form so that you will know what point to graph as the vertex of the parabola.
c) To identify the vertex, maximum and minimum, it is better to use vertex form because the vertex form will give the values of the coordinates for the vertex. Then, you can use the equation to find the mininmum or maximum. If the graph is negative, it will have a maximum because it points downward infinitely. If the equation is positive, the graph will have a minimum because the graph points upward infinitely.
d) Standard form is easier to use when trying to solve using the quadratic formula because it is easier to see what the coeffiecnts and constants are to plug in for a b and c.
Answer:
13
Step-by-step explanation:
4 * 3 = 12
Answer:
x - 10 = 75, or the second one
Step-by-step explanation:
The first, third, and fourth one is all equations that can help determine the measure of angle C, not D.
Hope this helps!!
Plz let me know if I'm wrong...
Kira did because by the time she walked for 45 minutes, she would be above 2 miles
Answer: ![\boldsymbol{-7}m + \boldsymbol{\frac{8}{5}}](https://tex.z-dn.net/?f=%5Cboldsymbol%7B-7%7Dm%20%2B%20%5Cboldsymbol%7B%5Cfrac%7B8%7D%7B5%7D%7D)
Work Shown:
![-\frac{2}{5}(15m-4)-m\\\\-\frac{2}{5}(15m)-\frac{2}{5}(-4)-m\\\\-6m+\frac{8}{5}-m\\\\\boldsymbol{-7}m + \boldsymbol{\frac{8}{5}}](https://tex.z-dn.net/?f=-%5Cfrac%7B2%7D%7B5%7D%2815m-4%29-m%5C%5C%5C%5C-%5Cfrac%7B2%7D%7B5%7D%2815m%29-%5Cfrac%7B2%7D%7B5%7D%28-4%29-m%5C%5C%5C%5C-6m%2B%5Cfrac%7B8%7D%7B5%7D-m%5C%5C%5C%5C%5Cboldsymbol%7B-7%7Dm%20%2B%20%5Cboldsymbol%7B%5Cfrac%7B8%7D%7B5%7D%7D)
Therefore -7 goes in the first box, and
goes in the second box.
