Answer:

  {-1.47, 1.14}

Step-by-step explanation:

The solution to ...

  ax^2 +bx +c = 0 is ...

  x=\dfrac{-b\pm\sqrt{b^2-4ac}}{2a}

Filling in the values a=3, b=1, c=-5, the solutions are ...

  x=\dfrac{-1\pm\sqrt{1^2-4(3)(-5)}}{2(3)}=\dfrac{-1\pm\sqrt{61}}{6}\\\\\boxed{x\approx\{-1.47,1.14\}}

Original price $69.80 with a 15% discount, what is the new price.
Mandarinka [93]

Answer:

$59.33

Step-by-step explanation:

To begin, let's start with what we know

Item = 69.80

Discount = 15% or 0.15

So, let's put it into this formula

New Price = Item ( 1 - Discount)              Note: P is the final price

                 = 69.80 ( 1 - 0.15)

                 = 69.80 ( 0.85 )

                 = 59.33

The new price is $59.33.

If you have any questions, please let me know in the comments. If you could mark this answer as the brainliest, I would greatly appreciate it!
