4x^2 + x + 3 = 0
x = [-1 +/- sqrt (1^2 - 4 * 4 * 3)] / 8 = - 1 +/- sqrt ( --47) / 8
= ( - 1 +/- sqrt47i) / 8 = -0.125 + 0.857i , -0.125 - 0.857i
10.5 small boxes equals the same amount of cereal in a large box
<h3>
How to determine the value</h3>
From the information given, let:
n is the number of smaller boxes
We know that:
Then,
12 + 7.6n = 6 + 8n
collect like terms
8n - 7. 6n = 12 - 6
0. 4n = 6
n = 6/ 0. 4
n = 15
The amount of cereal in a large box is;
6 + 8n = 6 + 8 (15) = 126 ounces
The amount of cereal in the smaller box is 12 ounces
Divide the volume of the larger box by the volume of the smaller box;
= 126/ 12
= 10. 5 smaller boxes
Hence, 10.5 small boxes equals the same amount of cereal in a large box
The complete question:
A cereal box manufacturer changes the sizeof the box to increase the amount of cereal it contains. The equations 12 + 7.6n and 6 + 8n, where n is the number of smaller boxes, are both representative of the amount of cereal that the new larger box contains. How many smaller boxes equal the same amount of cereal in the larger box?

It would be 10 because the factors add up and it makes sense
The equation would be: Y= 1/2x-1. Reasoning: Our equation format is Y=mx+b. Consider y to just be there for the mean time, but mx is where we insert our slope. We already know what our slope is in this equation (1/2) so that’s what we’ll insert, changing mx to 1/2x. B is where we put our Y. In this coordinate, our Y is -1 (keep in mind that a coordinate is set up as so: (x,y). Insert all our numbers to replace the variables and you get Y=1/2x-1
