Answer: x = the quantity of 5 plus or minus the square root of 29 all over 2
Step-by-step explanation:
The given quadratic equation is expressed as
x² - 5x - 1 = 0
The equation is already in the standard form of ax² + bx + c
The general formula for solving quadratic equations is expressed as
x = [- b ± √(b² - 4ac)]/2a
From the given quadratic equation,
a = 1
b = - 5
c = - 1
Therefore,
x = [- - 5 ± √(- 5² - 4 × 1 × - 1)]/2 × 1
x = [5 ± √(25- - 4)]/2
x = [5 ± √29]/ 2
x = ( 5 + √29)/- 2 or x = (5 - √29)/2
Area of a sphere formula = 4/3 pi x r^3
4/3 pi x 4^3 x 0.075 = 20.106
20.106 rounds to 20 to the nearest pound
Since all of the variables are y^3, all we have to do is the addition and subtraction of the whole numbers...
2y^3 - 3y^3 + 3y^3 - 4y^3 =
-2y^3
***Notice that the -3y^3 and 3y^3 just cancel out so all you have to do is the
2-4 = -2
Piece of cake :)
Answer:
|x-4| +|y-5|=0
Step-by-step explanation:
There are many equations that will graph as the point (x, y) = (4, 5). One of them is ...
|x-4| +|y-5| = 0
