Answer:

\text{The solution is }\frac{\sqrt{88}-4}{6}

Step-by-step explanation:

Given that Brahmagupta’s solution to a quadratic equation of the form

ax^2+bx=c involved only one solution.

we have to find the solution for the equation

3x^2 + 4x = 6

\text{The solution for the equation }ax^2+bx=c is

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

\text{The solution for the equation }3x^2+4x=6 is

x=\frac{\sqrt{4(3)(6)+4^2}-4}{2(3)}

x=\frac{\sqrt{72+16}-4}{6}

x=\frac{\sqrt{88}-4}{6}

Hey There!

Here is your answer:

First write the equation down:

-3 4/5 ÷ -3 1/6

Then put the mixed fractions into whole numbers:

-3 4/5= 5×-3=-15+4=-11= -11/5
&
-3 1/6= 6×-3=-18+1=-17= -17/6

Now right the new problem:

-11/5×6/-17

Now multiply:

-11×6=-66
5×-17=-85

Which means -66/-85 is your answer!

Hope this helps!

Draw 2 cards from a standard deck of 52 cards. What is the probability that the first card is a queen and the second card is a k
bixtya [17]

Answer:

4/663

Step-by-step explanation:

There are four queens.  The probability that the first card is a queen is 4/52.

There are four kings.  There are 51 cards left after the first card has been drawn, so the probability that the second card is a king is 4/51.

Therefore, the probability that the first card is a queen AND the second card is a king is:

P = 4/52 × 4/51

P = 4/663

The table shows the charges for using an internet service. Nicholas use the internet service for 16 hours and 40 Minutes last mo
yanalaym [24]

Answer:

<u>A. Nicholas will have to pay less using plan A</u>

<u>B. He will pay US$ 4 less than plan B</u>

Step-by-step explanation:

Let's compare how much Nicholas will pay on internet service in Plan A and plan B, after using it 16 hours and 40 minutes.

Plan A

Up to 10 hours = US$ 6

Every subsequent 1/2 hour: $1

10 hours + 14 (1/2 hour)

<u>Nicholas will pay 6 + 14 * 1 = US$ 20</u>

Plan B

Up to 12 hours = US$ 4

Every subsequent 1/2 hour: $2

12 hours + 10 (1/2 hour)

<u>Nicholas will pay 4 + 2 * 10 = 24</u>
