How to find the inverse of a function.

- Replace f(x) with y

- Swap x and y places. (sign doesn't matter here.)

- solve for y.

f(x) = 8√x

y = 8√x

x = 8√y

x^2 = (8√y)^2

x^2 = 64y

y = x^2 / 64

= (1/64) x^2

Answer:

Step-by-step explanation:

Because you just have to replace and what would it give = 8(3) -(-5) = 29

Answer:

x = 3

Step-by-step explanation:

In order to solve this equation, first we need to make the equation easier to read.

So instead of:

8x - (-5) = 29

We will do:

8x + 5 = 29

(Note that we have a plus sign now, because subtracting a negative number is the same as adding a positive number.)

Next we move the 5 to the other side of the equal sign, by subtracting it.

Now we have:

8x = 24

Finally we isolate the x variable, by dividing by 8 on both sides.

(24 ÷ 8 = 3)

Our answer is 3, therefore x = 3.

Answer:

Option A f(x) = a(x - 2)^2 + 5

Step-by-step explanation:

Vertex Form : y = a(x-h)^2 + k

In this case, we don't need the a-term because we are only looking for the vertex.

The h-term is how this parabola moved horizontally.

Since the x value is 2, that means that the graph moved 2 spaces towards the right. We plug it in to get:

y = (x - 2)^2

Now we need to find the k value. We see that the vertex is (2,5), and the y-value is 5. That means that the graph moved up to 5 units. Now we plug 5 into the k-value, and this is what we get:

y = (x - 2)^2 + 5

Walah! We're done with the equation, and as we can see, the answer is option A!

It really depends on what you need. In terms of cents per ounce, the 14-ounce box is the cheaper option per ounce. However if you only need a little, it does not make sense to pay more just for the sake of sale. Just buy the 10 ounce box. However if you need bulk, it makes more sense to buy the 14 ounce boxes because, in the end, it will end up being cheaper.

Answer:

$1.86 for 10 oz is a better buy by a very small amount.

Step-by-step explanation:

To answer the question, we find the unit rates of both boxes.

$1.86 for 10 oz:

unit rate = $1.86 / 10 oz = $0.186/oz

$2.61 for 14 oz:

unit rate = $2.61 / 14 oz = $0.18642857142.../oz

$1.86 for 10 oz is a better buy by a very small amount.

Answer:

65038.55

Step-by-step explanation:

First, Let's turn 12.3% into a decimal which is 0.123

Then Multiply 57,915 by 0.123

57,915 × 0.123= 7123.545 Round; 7,123.55

Then Add  [Mark up = Add] 57,915 with 7,123.55

57,915 + 7,123.55= 65038.55

Hence, the Answer is 65038.55

Answer:

A. 94 degrees

Step-by-step explanation:

Both the angles are similar and can be called parallel angles.

They are equal to each other so:

m∠2 = m∠3

4x - 26 = 3x + 4

4x - 3x = 4 + 26

x = 30°

m∠2 = 4x - 26

        = 4(30) - 26

        = 94°

Answer:

∠ 2 = 94°

Step-by-step explanation:

∠ 2 and ∠ 3 are vertically opposite angles and are congruent, so

4x - 26 = 3x + 4 ( subtract 3x from both sides )

x - 26 = 4 ( add 26 to both sides )

x = 30

Then

∠ 2 = 4x - 26 = 4(30) - 26 = 120 - 26 = 94°

Answer:

The equation is true

Step-by-step explanation:

Both sides are equal and they are all real numbers

Any value of x makes the equation true.

The slope of the function to 3 dp is 0.280

Slope is also known as the gradient of a function

Given the function [tex]f(x) =\frac{7}{x}[/tex]

Taking the derivative of the function will give:

[tex]f'(x)=-\frac{7}{x^2}[/tex]

Substitute x = 5 into the equation to have:

[tex]f'(x)=-\frac{7}{5^2}[/tex]

[tex]f'(x) = -\frac{7}{25}[/tex]

Hence the slope of the function to 3 dp is 0.280

Answer:  x = 34º,  y = 146º,  z = 146º

Step-by-step explanation:

Adding the angles inside a triangle gives you 180º. So

85 + 61 + x = 180

146 + x = 180

x = 34º

x and y are supplementary, so y = 180 - x = 180 - 34 = 146º.

y and z are equal (vertical angles), so z = 146º.

As per question,

[tex]10x + 18 < - 2 \\ = > 10x < - 2 - 18 \\ = > 10x < - (2 + 18) \\ = > 10x < - 20 \\ = > x < - \frac{20}{10} \\ = > x < - 2[/tex]

Therefore, the option X < -2 is correct.

Answer:

6

Step-by-step explanation:

to answer this we do the following:

24 - s = 6 x 3 (which is 18)

24 - s = 18

now the equation literally says '24- s has to equal 18'

so we work out s by: 24-18= 6

so s has to equal 6
