Ok, so here your being asked to solve 6x2<span> + 5x = -7
The procedure that I did was using this formula it led me to get the following:
</span>Using the formula:
x = -(-5) ± √(-5)² - 4(6)(-6)/ 2(6)
x = 5 ± √ 25 + 144 / 12
x = 5 ± √ 169 / 12
x = 5 ± 13/12
x1 = 5 + 13/12
x1 = 18/12
x1 = 3/2
x2 = 5 - 13/12
x2 = -8/12
<span>
x2 = - 2/3
Hope this helped :)</span>
<span>15 eggs and 16 cups flour </span>
<span>Pumpkin bread (x) : 2 eggs & 3 cups of flour </span>
<span>Coffee cake (y) : 3 eggs & 4 cups of flour </span>
<span>2x + 3y ≤ 15 { number of eggs used} </span>
<span>3x + 4y ≤ 16 { number of cups of flour used } </span>
<span>Objective function </span>
<span>P = 5x + 4y</span>
