Equation

Total = movies plus songs.

Givens

Total = 100

Movies = 48.4

Songs Cost = x

Number of Songs = 40

Solve

100 = 48.4 + 40x       Subtract 48.4 from both sides.

100 - 48.4 = 40x

51.6 = 40x                  Divide by 40

51.6 / 40 = x

1.29 = x

Conclusion

Each song cost $1.29

What is the solution to this equation pls pls pls<br><br> x(at the power of 2) = 6 + 9x
kati45 [8]

Answer:

The solution to the equation are x = 5.089  and    x = -0.589

Step-by-step explanation:

Given:

x(at the power of 2) = 6 + 9x

To Find:

The solution of the equation = ?

Solution:

The given equation can be written as  

=> 2x^2 = 6+9x

=>2x^2-6 -9x=0

=>2x^2-9x-6=0

Using the quadratic formula,

x = \frac{-b\pm \sqrt{(b^2 -4ac}}{2a}

where

a= 2

b = -9

c = -6

Substituting these values,

x = \frac{-(-9)\pm \sqrt{(-9)^2 -4(2)(-6)}}{2(2)}

x = \frac{-(-9)\pm \sqrt{(81) -4(-12)}}{2(2)}

x = \frac{-(-9)\pm \sqrt{81+48}}{4}

x = \frac{-(-9)\pm \sqrt{129}}{4}

x = \frac{-(-9)\pm 11.357}{4}

x = \frac{9 \pm 11.357}{4}

x = \frac{9 + 11.357}{4}                        x = \frac{9 - 11.357}{4}

x = \frac{20.357}{4}                            x = \frac{-2.357}{4}  

x =5.089                                                           x =   -0.589

Use slope formula to find slope <span><span><span>−9−5</span><span>−/12−8</span></span>=<span><span>−14/</span><span>−20</span></span>=<span>7/10</span></span> 7/10 = m = slope  
y= mx + b
y= (7/10)x + b
(8,5)
(5) = (7/10)(8) + b
b = -3/5

So.... <span>y=(<span>7/10)</span>x −<span>35

</span></span> multiply by 10

<span>10y=7x−6</span><span> --> -7x + 10y = -6
 --> 7x - 10y = 6
 So, if 7x - 10y = 3 a good model?</span>
