Remember that multiplying is how many times you add a number to itself. If you multiply by 3, you add the first number to itself 3 times.

When you multiply a given number by 1, you get the first number (it doesn't change).

When you multiply by a number less than one, say, one half, you'll end up with half of the original number --> a smaller number.

When you multiply a number by more than one, you will get a number bigger than the original because you are adding it to itself more than once. Even if it is a fraction or decimal, if it is greater than 1, then the new product will be larger than the original number.

Hope this helps! :)

PLEASE HELP!! 20 POINTS PLUS BRAINLIEST IF YOURE RIGHT!!

Firstly, we have to find the mean. The mean is simply the average of the numbers, which we find by adding each number in the sequence and then dividing that result by the total amount of numbers.

13.3 + 14.3 + 15.3 + 16.3 + 17.3 = 76.5

76.5 / 5 = 15.3

Okay, so our average is 15.3.

Now, we have to subtract the mean from each number and then square the result.

(13.3 - 15.3)^2 = 4
(14.3 - 15.3)^2 = 1
(15.3 - 15.3)^2 = 0
(16.3 - 15.3)^2 = 1
(17.3 - 15.3)^2 = 4

Now we have to find the mean of those numbers!

4 + 1 + 0 + 1 + 4 = 10

10 / 2 = 2

Finally, we take the square root of that number and we have our standard deviation. =)

What is the equation of the line that passes through the point (2,-2) and has a slope of -1/2?

katrin2010 [14]

Answer:

y = -1/2x - 1

Step-by-step explanation:

We can use the point-slope form of the equation:

y-y1 = m(x-x1)

Where the given y1 = -2, x1 = 2, and m = -1/2. This yields:

y - (-2) = -1/2(x - 2)

y + 2 = -1/2x + 1

y = -1/2x +1 - 2

y = -1/2x - 1

The function f(x) = 7x + 1 is transformed to function g through a horizontal compression by a factor of 1/3. What is the equatio

Iteru [2.4K]

Answer:

The answer is "3".

Step-by-step explanation:

If the compression factor of 3 is modified, the k value is 3 For a function f(x) the horizontal extending or compression is provided by g = f (bx)

Here b is constant. Where b is constant.

If b> 0, the function graph is condensed. The fact that perhaps the function is transformed by an encoding factor of 3 is given in the question.

$\to f(x)=7^x+1\\\\\to g=f(b(x))$
