What is the solution set of 2x(x - 1) = 3?

garik1379 [7]

First you must distribute the 2x to the numbers inside the parentheses

(2x * x) + (2x * -1) = 3

$2x^{2}$ - 2x = 3

To make this a quadratic equation you can solve bring the 3 over to the left side of the equation by subtracting it to both sides

$2x^{2}$ - 2x - 3 = 0

Use the quadratic equation to solve this (image of the quadratic equation is below)

Remember that quadratic functions are set up like so:

$ax^{2} +bx +c = 0$

That means that in this equation...

a = 2

b = -2

c = -3

^^^Plug these numbers into the quadratic equation and solve...

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

$\frac{2 +/-\sqrt{4+24}}{4}$

$\frac{2+/-\sqrt{28} }{4}$

$\frac{2+/-2\sqrt{7} }{4}$

$\frac{1+/-\sqrt{7} }{2}$

Keep in mind that +/- is ±

$\frac{1+\sqrt{7} }{2}$

$\frac{1-\sqrt{7} }{2}$

326 people were in a tour group. Six buses were completely filled and 8 people chose to walk. How many people did the bus hold?

Artemon [7]

Answer:

The Total Capacity per bus is 53 people.

Step-by-step explanation:

To work this out you would first minus 8 from the total to find out how many actually went on the bus, and so we do not count the people walking. Then as you know there are six busses you would divide that new total by 6 to find the capacity per bus.

1) Minus 8 from 326.

$326-8=318$

2) Divide that by 6.

$318/6=53$

3) Total capacity.

The Total Capacity per bus is 53 people.

This shows that the total capacity per each bus is 53 people.

Mrs. Valdez wanted to determine the number of people, p, she could safely take in her car to the fun run. She determined that p

dolphi86 [110]

Answer:

for the first question b,

it doesn't make sense for choice a to have -2 people in the car. You can't have a negative amount of people. For choice choice c, you can't have half a person, and for choice d, Ms. Valdez can only have under 5 people, not five people exactly.

for the second question I need to see the whole inequality, generally there is a variable, and all i see is <-1, which is invalid.

hope this helps, if it does like it pls!!
