The positive solution to the quadratic equation 
is x = 1.39
<h3><u>Solution:</u></h3>
Given quadratic equation is
<em><u>The general quadratic equation is of form:</u></em>
Now comparing the general equation with the given equation we get
a = 2 , b = 3 and c = -8
<em><u>The formula to determine roots of the quadratic equation is:</u></em>
On plugging in vlaues, we get
On solving we get,
x = 1.39 OR x = -2.89
Hence , the positive solution to the quadratic equation is x = 1.39
Answer is A.
You start by adding the 7 to the opposite side. Giving you 19. You divide both sides by -2 which gives you x on one side and -9.5 on the other.
-2x-7=12
-2x=12(+7)
-2x=19
x=19/-2
x=-9.5

Answer:
8.6%
Step-by-step explanation:
To find the percent change, you will need to compute the positive difference and then divide the difference by the original (the older amount).
So the positive difference will be obtain by doing larger minus smaller:
6300
- 5800
-----------
500
The older amount was 5800.
So 500/5800 is the answer as a un-reduced fraction.
I'm going to reduce it by dividing top and bottom by 100:
500/5800 = 5/58
5/58 is the answer as a reduced fraction.
5 divided by 58 gives=0.086206897 in the calculator .
Approximately 0.0862 is the answer as a decimal.
To convert this to a percentage, multiply it by a 100:
8.62%
Rounded to the nearest tenths is 8.6%
-------------
So 5800+5800(.0862) should be pretty close to 6300 (not exactly though since we rounded).
5800+5800(.0862)=6299.96 using the calculator.
