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.

What value of x is in the solution set of 2x - 3 &gt; 11 - 5x<br><br><br> -3<br> 0<br> 2<br> 4
Misha Larkins [42]

<u>Answer:</u>

The answer is D : 4.

<u>Step-by-step explanation:</u>

<em>=2x-3>11-5x</em>

<em>=2x-3+5x>11</em>

<em>=7x-3>11</em>

<em>=7x>11+3</em>

<em>=7x>14</em>

<em>=7x/7>14/7</em>

<em>=x>2</em>

<em />

<em />

<em>By simplifying the problem, you can see that "x" </em><em><u>must</u></em><em> be greater than 2. Therefore, eliminating all other possible answers that are shown, but 4. </em>

Christine went shopping and bought each of her six nephews a gift, either a video costing $14.95 for a CD costing $16.88. She sp
andrezito [222]

Let v = number of video's she bought

Let c = number of CD's she bought

v+c=16

1495v+1688c=9355

Multiply both sides of (1) by 1495

and subtract (1) from (2)

-1495v-1495c=-8970

193c=386

c=2h
