- 2x – 5 &lt; 12<br> Yo help
Elina [12.6K]

Answer:

x > -17/2

Step-by-step explanation:

Step 1: Write inequality

-2x - 5 < 12

Step 2: Solve for <em>x</em>

<u>Add 5 to both sides:</u> -2x < 17

<u>Divide both sides by -2:</u> x > -17/2

Here, we can see that any number greater than -17/2 would work, so x could equal 01234718905731857013570 if we wanted it to, as long as it is greater than -8.5.

Answer please in less that 10 minutes​
Andreyy89

Answer:

Step-by-step explanation:

Since we have an x under that radical, we have to get it out from under there.  To do that, do the opposite of the square root, which is to square.  But because this is an equation, you have to do the same thing to both sides.  Doing this gives you

6x-9=x^2

Get everything on one side and set the quadratic equal to 0 and solve for x:

x^2-6x+9=0

Factor this into 2 factors of (x - 3)(x - 3) = 0.  As you can see they are both the same, so x - 3 = 0 and x = 3.  That's your answer.  x = 3.

The expected number of heads in 500 tosses of an unbiased coin is:
Lostsunrise [7]
There is a 50%, or 1/2, chance of getting heads on each flip. Each of the 500 trials is independent. Because there is a 1/2 chance of getting heads, you would expect half of them to land on heads. 500/2 = 250. You would theoretically expect  250 heads if you tossed an unbiased coin 500 times.
