Consider this quadratic equation. 2x2 − 1 = 3x + 4 Which equation correctly applies the quadratic formula?
Mariulka [41]

Answer:

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

Step-by-step explanation:

Quadratic formula: \frac{-b+-\sqrt{b^2-4ac} }{2a}

2x^2-1=3x+4\\\\2x^2-3x-5=0\\\\\\frac{-(-3)+-\sqrt{(-3)^2-4(2)(-5)}}{2(2)} \\\frac{3+-\sqrt{9+40} }{4}

x = \frac{3+-7}{4}

Hope this helps and God bless!

Solve x -2/3(3x - 4) + 3x = 5/6 is x -19/6, 11/6, 21/6, 29/6
Tanzania [10]

Answer:

x=-11/12

Step-by-step explanation:

Given an equation for x

x -2/3(3x - 4) + 3x = 5/6

We are asked to find the value of x.

We use equation rules to solve

To get rid of denominator in fraction, let us multiply the whole equation by 6.

6x-4(3x-4) +18x = 5

Simplify:

-6x+18x+16 =5

12x = 5-16 = -11

x = -11/12

You are going to buy some cable television ads. You can get 20 spots for $1200 or 80 spots for $3200 what is the percentage disc
Lesechka [4]

Answer:

  33 1/3%

Step-by-step explanation:

When you buy 20 ads, the per-ad rate is

  $1200/20 = $60 . . . per ad

When you buy 80 ads, the per-ad rate is

  $3200/80 = $40 . . . per ad

The percentage change to the $60 price is ...

  ((new price) - (original price))/(original price) × 100%

  = ($40 -$60)/$60 × 100% = -20/60 × 100%

  = -1/3 × 100% = -33 1/3%

The higher volume purchase comes with a 33 1/3% discount.
