Answer:

78 pages

Step-by-step explanation:

Find out 22% using 1% of the number of photos the album can hold.

100% = 800

1% = 800 ÷ 100 = 8

22% = 8 x 22 = 176

800 - 176 = 624

The album has 624 photos.

If 8 photos can create a page...

624 ÷ 8 = 78 pages

Answer:23

Step-by-step explanation:

Answer:

25

Step-by-step explanation:

In this it's going to be pretty simple.

[tex]b^{2}[/tex] is going to be -3 * -3 = 9

When you have a square you multiply the number by itself.

So

9 - 4 * 1 * -4

here you have to remember order of operations.

Please - Parens

Excuse - Exponents

My - Multiplication

Dear - Division

Aunt - Addition

Sally - Subtraction.

Multiplication and Division are done at the same time left to right

Addition and Subtraction are done at the same time left to right.

So

9 - 4 * 1 * -4

You do the multiplication first.

4*1 = 4

4 * -4 = -16

Now you have

9 - - 16

This turns into

9 + 16

your answer is 25.

Step-by-step explanation:

Answer:

multiplication property of equality

Step-by-step explanation:

d/10=12

Multiply both sides by the equation by 10

10× d/10=10×12

Reduce the numbers by the greatest common factor which is 10

d=10×12

Multiply 10 and 12

d=120

So using multiplication to solve this equation

Answer:

g(x) is f(x) stretched vertically by a factor of 4

Step-by-step explanation:

Since g(x) = 4 x^2, the graph of g(x) is a vertically stretched (by a factor of 4) version of the graph of f(x).

I think the answer is the train travels about 23.42

Answer Before defining the inverse of a function we need to have the right mental image of function.

Consider the function f(x) = 2x + 1. We know how to evaluate f at 3, f(3) = 2*3 + 1 = 7. In this section it helps to think of f as transforming a 3 into a 7, and f transforms a 5 into an 11, etc.

Now that we think of f as "acting on" numbers and transforming them, we can define the inverse of f as the function that "undoes" what f did. In other words, the inverse of f needs to take 7 back to 3, and take -3 back to -2, etc.

Let g(x) = (x - 1)/2. Then g(7) = 3, g(-3) = -2, and g(11) = 5, so g seems to be undoing what f did, at least for these three values. To prove that g is the inverse of f we must show that this is true for any value of x in the domain of f. In other words, g must take f(x) back to x for all values of x in the domain of f. So, g(f(x)) = x must hold for all x in the domain of f. The way to check this condition is to see that the formula for g(f(x)) simplifies to x.

g(f(x)) = g(2x + 1) = (2x + 1 -1)/2 = 2x/2 = x.

This simplification shows that if we choose any number and let f act it, then applying g to the result recovers our original number. We also need to see that this process works in reverse, or that f also undoes what g does.

f(g(x)) = f((x - 1)/2) = 2(x - 1)/2 + 1 = x - 1 + 1 = x.

Letting f-1 denote the inverse of f, we have just shown that g = f-1.

Definition:

Let f and g be two functions. If

f(g(x)) = x and g(f(x)) = x,

then g is the inverse of f and f is the inverse of g.

Finding Inverses

Example 1. First consider a simple example f(x) = 3x + 2.

The graph of f is a line with slope 3, so it passes the horizontal line test and does have an inverse.

There are two steps required to evaluate f at a number x. First we multiply x by 3, then we add 2.

Thinking of the inverse function as undoing what f did, we must undo these steps in reverse order.

The steps required to evaluate f-1 are to first undo the adding of 2 by subtracting 2. Then we undo multiplication by 3 by dividing by 3.

Therefore, f-1(x) = (x - 2)/3.

Steps for finding the inverse of a function f.

Replace f(x) by y in the equation describing the function.

Interchange x and y. In other words, replace every x by a y and vice versa.

Solve for y.

Replace y by f-1(x).

Example 2.  f(x) = 6 - x/2

Step 1 y = 6 - x/2.

Step 2 x = 6 - y/2.

Step 3 x = 6 - y/2.

y/2 = 6 - x.

y = 12 - 2x.

Step 4 f-1(x) = 12 - 2x.

Step 2 often confuses students. We could omit step 2, and solve for x instead of y, but then we would end up with a formula in y instead of x. The formula would be the same, but the variable would be different. To avoid this we simply interchange the roles of x and y before we solve.

Example 3.  f(x) = x3 + 2

This is the function we worked with in Exercise 1. From its graph (shown above) we see that it does have an inverse. (In fact, its inverse was given in Exercise 1.)

Step 1 y = x3 + 2.

Step 2 x = y3 + 2.

Step 3 x - 2 = y3.

(x - 2)^(1/3) = y.

Step 4 f-1(x) = (x - 2)^(1/3).

Exercise 3:

Graph f(x) = 1 - 2x3 to see that it does have an inverse. Find f-1(x). Answer
