The expression that is equivalent to [3/(x + 1)] ÷ 1/(x + 1)] after simplification is gotten as; 3

<h3>How to simplify fractions?</h3>

We want to simplify the expression;

[3/(x + 1)] ÷ 1/(x + 1)]

This fraction expression will be re-expressed as;

[3/(x + 1)] * (x + 1)/1

x + 1 will cancel out to give us the expression as;

[3/(x + 1)] * (x + 1)/1 = 3

Pls help. Just need the formula to enter into the "y=" slot. Thank you :)

Answer:

I believe its y= $7^{2}$

My thinking:

I think when the slope intercepts the Y line is when it’s called the y-intercepts and that’s basically how got my answer.

Please do correct me if I’m wrong

It’s been a while since I done something like that ( it hasn’t been that long actually, I just forgot a lot of it)

Sorry if I’m wrong, I hope that I at least helped a Little

For the dilation, DO, K = (10, 0) → (5, 0), the scale factor is equal to _____. -5 5 0.5 2

ozzi

Answer:

The scale factor of the following dilation is, 0.5

Step-by-step explanation:

The rule of dilation with scale factor k is given by:

$(x, y) \rightarrow (kx, ky)$

As per the statement:

Given the following dilation:

(10, 0) → (5, 0) .....[1]

We have to find the scale factor.

Using the above rule we have;

$(10, 0) \rightarrow (10k, 0k)$

Now compare this with equation [1] we have;

(10k, 0) = (5, 0)

⇒10k = 5

After solving we get;

$k = \frac{1}{2}=0.5$

Therefore, the scale factor of the following dilation is, 0.5

F(x)=2x+3 and g(x)=4x-2. Find f(x) x g(x). Find f(x) - g(x).

const2013 [10]

Answer:

f(x) * g(x) is 8x^2 + 8x -6

f(x) - g(x) is -2x + 5

Step-by-step explanation:

When finding the answer, we can notice they already give the values for the needed answers.

The first one requires f(x) and g(x). At the beginning of the question it shows that f(x) is equal to 2x+3. Meaning we can plug in 2x+3 for f(x).

The same goes for g(x). At the begginning of the question, it shows that g(x) is equal to 4x-2. Meaning we can plug in 4x-2 for g(x).

f(x) * g(x)

(2x+3) * (4x-2)

To find the answer, we need to distibute the 2x+3 into 4x-2.

To distribute, we do :

2x * (4x-2) + 3 * (4x-2)

First we distribute the 2x

2x * 4x = 8x^2 and 2x * -2 = -4x

8x^2 - 4x

Next we distibute the 3

3 * 4x = 12x and 3 * -2 = -6

12x - 6

Now we can combine them by adding like terms to get the asnwer:

8x^2 = 8x^2

-4x + 12x = 8x

-6 = -6

The first answer is 8x^2 + 8x -6

Second question:

Since we already know the values for f(x) and g(x), all we have to do is plug in the values.

(2x+3) - (4x-2)

This time, since we are subtracting, all we have to do is subtract like terms.

2x - 4x = -2x

3 - (-2) = 5

The second answer is -2x + 5
