Answer:

Step-by-step explanation:

Formula

\frac{-b +/- \sqrt{b^2 - 4ac} }{2a}

Givens

a = 9

b = - 9

c = -18

Solution

\frac{- (-9) +/- \sqrt{(-9)^2 - 4*9*(-18)} }{2*9}\\\\\frac{9 +/- \sqrt{81 + 4*9*18} }{18} \\\\\frac{9 +/- \sqrt{ 81 + 288} }{18}\\\\

9 +/- √369

=============

      18

9 +/- 3*√41

==========

      18

x = 9 +/- 19.209

Nadusha1986 [10]

Answer:

Whitney made 6 baskets

Step-by-step explanation:

Let the number of baskets made by Whitney be x.

The 15 baskets made by

Chiyann is equal to 2 times plus 3 what Whitney made

Mathematically what she made would be 2x + 3

To get x, we equate this equation to 15

2x + 3 = 15

2x = 12

x = 12/2

x = 6 baskets

Find the general solution to the equation y(5) - 4y(4) + 4y(3) = 1.
tensa zangetsu [6.8K]

Answer:

y= -1/23

Step-by-step explanation:

The equation y(5)-4y(4)+4y(3)=1 can be solved thus:

Work on brackets first:

5y-16y+12y=1

Add up y values

5y-28y=1

Divide both sides of equation

-23y=1

y=1/-23

Therefore the value of y is -1/23
