Step-by-step explanation:
The given quadratic equation is expressed as
x² = 5 - x
Rearranging the equation to take the standard form of ax² + bx + c, it becomes
x² + x - 5 = 0
The general formula for solving quadratic equations is expressed as
x = [- b ± √(b² - 4ac)]/2a
From the equation given,
a = 1
b = 1
c = - 5
Therefore,
x = [- 1 ± √(1² - 4 × 1 × - 5)]/2 × 1
x = [- 1 ± √(1 - - 20)]/2
x = [- 1 ± √21]/2
x = (- 1 + √21)/2 or x = (- 1 - √21)/2
Option 2 because in option one 7.5% of $300 is $22.50 so more would be put in if he chose the second option
The correct answer would be 48 min. (Choice B)
In an inverse relationship, we multiply the 2 variables together to get a constant.
Our equation would be:
GT = C If we plug in the numbers we have:
8(12) = 96
Now, lets solve the equation for T when G is 2.
2T = 96
T = 48
