Can anyone help me in explaining subtraction of polynomials please help I’m desperate and I’m pretty much on my own when it come
Sidana [21]

Answer:

Think of combining <u>like terms</u> when subtracting polynomials. For example, 3x² and -2x². They both have x² in common. So, if you were to combine 3x² and -2x², it would be like 3x² + (-2x²). Think of this like 3 + (-2), which equals 1. In this case, it would equal 1x² or x².

Let's take this problem for example: 6x² - 3x + 4 - (-2x² +2x - 2)

Parentheses are super important; The first thing you want to do is distribute the negative sign out to everything inside the parentheses!

So,

6x² - 3x + 4 - (-2x² +2x - 2) *multiply the neg. to -2x², 2x, and -2

Now, if you do that, the equation would now look like:

6x² - 3x + 4 + 2x² - 2x + 2

Now think of combining like terms. Here are the like terms:

6x² <em>- 3x</em> <u>+ 4</u> + 2x² <em>- 2x</em> <u>+ 2</u> (Let's rewrite it to look like this...)

6x² + 2x² <em>- 3x</em> <em>- 2x </em><u>+ 4</u> <u>+ 2</u>

Let's combine the x²'s first, so... 6x² + 2x² = 8x²

Let's combine the x's, so...<em> -3x - 2x = -5x</em>

Let's combine the constants (numbers with no variable), so... <u>4 + 2 = 6</u>

<u />

Your solution should be 8x² - 5x + 6

A jar contains 6 red marbles numbered 1 to 6 and 4 blue marbles numbered 1 to 4. A marble is drawn at random from the jar. Find
svetoff [14.1K]

Answer:

Step-by-step explanation:

A

The marble is red. There are 6 red marbles out of ten. So the answer is

6/10 = 0.60

B

Red: 1 3 5

Blue: 1 3

So there are 5 ways that you can draw an odd number. The problem is that they are not evenly distributed.

Red: 1/2 * 3/6 = 1/4 = 0.25

Blue: 1/2 * 2/4 = 0.25

Red + blue = 1/4 + 1/4 = 1/2

You could have gotten 1/2 by taking 5/10 but that won't always work.

Suppose the function f(x) = 0.035x represents the number of U.S. dollars equivalent to x Russian rubles, and the function g(x) =
const2013 [10]

Answer:

g(f(x)) = 3.15x

Step-by-step explanation:

To find the number of Japanese yen equivalent to x russian rubles, we need to put one function into another.

If we take f(x) and put in into g(x), we will get Japanese yen in terms of rubles. Thus,

g(f(x)) = 90 (0.035x)

g(f(x)) = 3.15x

THis is the composite function which represents the number of Japanese yen equivalent to x Russian Rubles.
