What's next in -3x+2+9x=4x-5-1

Mathematics

sweet [91]3 years ago

Firstly, you need to combine like terms within that side of the equation.
Take -3x +9x and you’ll get 6x.

Next, combine like terms on the other side of the equation.
Take -5-1 and you’ll get -6

So far you should have:
6x+2=4x-6

Subtract 4x on each side!! Cancel 4x-4x! Solve 6x-4x!

Now you’ll get:
2x+2=-6

Subtract 2 on each side!!
Cancel out 2-2 and solve -6-2.

You should get:
2x=-8

Lastly, divide 2 on each side.
Cancel out 2/2 and solve 8/2.

Your final answer should be:
X = -4

spayn [35]

Answer:

  a) 1/64

  b) 1/4096

Step-by-step explanation:

As you can tell from the example, the exponent of 1/2 is the number of heads in a row.

a) p(6 heads in a row) = (1/2)^6 = 1/(2^6) = 1/64

b) p(12 heads in a row) = (1/2)^12 = 1/(2^12) = 1/4096

_____

<em>Additional comment</em>

The probability of a head is 1/2 because we generally are concerned with a "fair coin." That is defined as a coin in which each of the 2 possible outcomes has the same probability, 1/2. Similarly, a "fair number cube" has 6 faces, and the probability of each is defined to be the same as any other, 1/6. Loaded dice and unfair coins do sometimes show up in probability problems.

mamaluj [8]
You write the problem as a mathematical expression
3x^2 + 30x + 75 =
Factor: 3 out of 3x^2 + 30x + 75.

3 (x2 + 10x + 25)

Factor using the perfect square rule.
And then your answer should be 3 ( x + 5) ^2
