if f(x) and f^-1(x) are inverse functions of eachother and f(x)=2x+5, what is f^-1(8)

Answer:

x > 12

Step-by-step explanation:

Step 1: Subtract 8 from both sides

[tex]\frac{1}{4}x[/tex] + 8 - 8 > 11 − 8

[tex]\frac{1}{4}x[/tex] > 3

Step 2: Multiply both sides by 4.

(4) ([tex]\frac{1}{4}x[/tex]) > (4) (3)

x > 12

Answer:

[tex]7x(x+2y-3yz)[/tex]

Step-by-step explanation:

First we find the greatest common factor of the coefficients, 7, 14 and 21.

The greatest common factor is 7.

Factor 7 out and divide the terms by 7:

[tex]7x^2+14xy-21xyz=7(x^2+2xy-3xyz)[/tex]

-----------------------------------------------------

Next, we find the greatest common factor of [tex]x^2,xy[/tex] and [tex]xyz[/tex].

The greatest common factor is x.

Factor x out and divide the terms by x:

[tex]7(x^2+2xy-3xyz)=7x(x+2y-3yz)[/tex]

Answer:

$41.48

Step-by-step explanation:

From the information given, you know that the price that the bookstore pays for a book is marked up 35% and that the selling price of a book is $56, so to be able to find the amount that the bookstore paid for a specific book, you can write the following equation:

x+0.35x=56, where x is the price the bookstore paid for the book.

Now you can solve for x:

1.35x=56

x=56/1.35

x=41.48

According to this, the bookstore paid $41.48 for this book.

Answer:

4.2

Step-by-step explanation:

Because 1/5 has to be converted into the 100 as the denominator and the number you are supposed to have for the numerator so it can be easier and 4 is the whole number so it doesnt need to be in the equation.

1/5

20= 20/100  so now all you have to do is make that a decimal since it hasnt got to 100 or past it and you have your answer

Answer:

Since, the coordinates of the midpoint of line GH are M(\frac{-13}{2}, -6)(

2

−13

,−6) .

The coordinates of endpoint G are (-4,1)

We have to determine the coordinates of endpoint H.

The midpoint of the line segment joining the points (x_1, y_1)(x

1

,y

1

) and (x_2, y_2)(x

2

,y

2

) is given by the formula (\frac{x_1+x_2}{2},\frac{y_1+y_2}{2})(

2

x

1

+x

2

,

2

y

1

+y

2

) .

Here, The endpoint G is (-4,1) So, x_1 = -4 , y_1=1x

1

=−4,y

1

=1

Let the endpoint H be (x_2,y_2)(x

2

,y

2

)

The midpoint coordinate M is (\frac{-13}{2}, -6)(

2

−13

,−6) .

So, \frac{-13}{2} = \frac{-4+x_2}{2}

2

−13

=

2

−4+x

2

{-13} = {-4+x_2}−13=−4+x

2

{-13}+4 = {x_2}−13+4=x

2

{x_2}=9x

2

=9

Now, -6 = \frac{1+y_2}{2}−6=

2

1+y

2

-12 = {1+y_2}−12=1+y

2

y_2= -13y

2

=−13

So, the other endpoint H is (-9,-13).

Answer:

x = -1/2

Step-by-step explanation:

3xy + 5x + 2 + 3y + x +4  -> 3x + 5x + 2 + 3x + x + 4 = 0

We add all the numbers together, and all the variables

12x+6=0

We move all terms containing x to the left, all other terms to the right

12x=-6

x=-6/12

x=-1/2

(remember, there should only be one variable)

The amount of water rounded to the nearest hundred should be 100 liters.

Since The Grayson family got a new backyard swimming pool. When they tell their friends how much water it holds, they round the number to 51{,}10051,10051, comma, 100 liters.

So based on this, if there is 51 liters so it should be rounded to 100 liters

Therefore, we can conclude that The amount of water rounded to the nearest hundred should be 100 liters.

0.672 is rational because it is a terminating decimal.

Step-by-step explanation:

to find the area more easily, you can divide the figure.

make a small rectangle from the upper part (a 5×6 rectangle) then a square from the lower part (a 5×5 square).

now you have a small rectangle, a big rectangle and a square.

small rectangle: 5×6=30

big rectangle: 15×5=75

square:5×5=25

30+75+25=130

Answer:

angle xyb will measure 123 degrees.

Step-by-step explanation:

because we know that angle ayz is 57 degrees and angle xyz is 90, we find that angle xya measures 33 degrees by subtracting 57 from 90. then, we can find angle xyb by subtracting 33 from 180, getting 147 degrees. when we add 147, 33, and 57, we get 237 degrees. finally, we subtract 237 from 360 and get 123 degrees, our final angle. hope this helps:)
