Which are the solutions of the quadratic equation x^2=-5x-3
frutty [35]
The correct answer would be \frac{-5 +/-  \sqrt{13} }{2}

In order to solve for this you must first get the equation equal to 0. 

<span>x^2=-5x-3 ----> add 5x to both sides. 
x^2 + 5x = -3 ----> add 3 to both sides.
x^2 + 5x + 3 = 0

Now knowing this we can use the coefficients of each one in descending order of power as a, b and c. 

a = 1 (because it is the coefficient to x^2)
b = 5</span> (because it is the coefficient to x)
c = 3 (because it is the end number)

Now we can plug these values into the quadratic equation. 

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

\frac{-5 +/- \sqrt{5^{2} - 4(3)(1) } }{2(1)}

\frac{-5 +/- \sqrt{13} }{2}

And those would be your two answers.

Pyotr Tchaikovsky Sporting Goods operates on a 45% overhead based on the selling price, which results in an overhead of $65.34 o
lapo4ka [179]

Answer:

Selling price of hockey game set is $145.32 , markup price is $210.54 and profit is $96 .

Step-by-step explanation:

Let us assume that the selling price of hockey game set be x .

As given

Pyotr Tchaikovsky Sporting Goods operates on a 45% overhead based on the selling price, which results in an overhead of $65.34 on the newest version of an air hockey game set.

45% is written in the decimal form .

= \frac{45}{100}

= 0.45

Thus the equation becomes  

0.45 × x = 65.34

0.45x = 65.34

x = \frac{65.34}{0.45}

x = 145.2

Therefore the selling price of the hockey game set is $145.2 .

Thus

Markup price = Selling price + Overhead Price

                      = $145.2 + $65.34

                      = $ 210.54

As given

If the air hockey game set costs Pyotr Tchaikovsky Sports $49.32 .

i.e Cost price of the  hockey game set = $ 49.32

Profit = Selling price -  Cost price

         = 145.32 - 49.32

         = $ 96

Therefore selling price of hockey game set is $145.32 , markup price is $210.54 and profit is $96 .

Select the correct answer.
Fofino [41]

The answer is C: (-3,-1)

To test if points satisfy an equation, all you need to do is test the numbers in both of the equations it provides you

Here is proof the answer is C :

<em>y > x - 2 </em>

(lets plug in point C)

-1 > -3 - 2

<u>solve </u>

-1 > -5 <em>?</em>

<em>Yes</em> this statement is true- onto the next inequalitity!

<em>y > 2x + 2 </em>

-1 > 2(-3) + 2

<u>solve </u>

-1 > -6 + 2

-1 > -4<em> ? </em>

<em>Yes, </em>this inequality is true too!

Know we know answer c (-3,-1) is the right answer!
