Functions I need help with 14-17

Answers

Answer:

14) No. 15) No. 16) Yes. 17) Yes.

Explanation:

When something is not a function, you can either use the vertical line test which involves drawing a line going up and down to see if the graph hits the line more than once. If this is the case, it is not a function. Or the input or x value of a function cannot have more than one

output or y value.

The line x = |y| on the graph of #14 is not a function because there is more than one y value for a single x value. This also hits a vertical line more than once.

The table on #15 is not a function because their is more than one y value per x value. It also hits a vertical line more than once.

The equation y = 1/4x is a function because there is only one output for each input. This also does not hit a vertical line more than once

The equation x = y - 1 is a function because it is simply a rearanged version of y = x + 1 which has only one output for each input. It also does not hit a vertical line more than once.

The quotient of a number and -5 has a result of 2. What is the number?

Type the correct answer in the box. Use numerals instead of words.

n =

Answers

Answer:

Answer is -10

Step-by-step explanation:

Explanation:

First, define the variable. Let n represent the unknown number.

Next, write an equation to represent the situation. Because a quotient is the result of division, divide the unknown number by -5:

.

Then, use opposite operations and the properties of equality to solve for n. Notice that the variable, n, is divided by -5. So, to isolate n, do the opposite and multiply both sides of the equation by -5:

Finally, to check the solution, substitute -10 for n in the original equation:

The resulting statement is true, so the solution is correct.

Are 4/7 and 12/21 equivalent fractions? Why or why not?

Answers

Answer:

Yes

Step-by-step explanation:

12/21 simplified is 4/7. if you divide the numerator (12) by 3 and the denominator (21) by 3, you get 4 and 7, or 4/7 if you put it together.

4/7 and 12/21 are equivalent fractions

What is Fraction?

A fraction represents a part of a whole.

We need to check whether the fractions  4/7 and 12/21  are equivalent or not.

Equivalent fractions are the fractions that have different numerators and denominators but are equal to the same value.

12/21 we have to simplify.

12 and 21 are the multiples of 3, so  divide numerator and denominator by 3

which gives 4/7

12/21=4/7

Hence, 4/7 and 12/21 are equivalent fractions

Answer:

A) [tex]5x-1=-6[/tex]

B) [tex]x=-1[/tex]

Step-by-step explanation:

On the left, we have five (positive) Xs and one -1. So, we can represent the left with the expression [tex]5x-1[/tex].

On the right, we have six -1s. So, we can represent the right with the expression [tex]-6[/tex].

A)

Since the balance is balanced, we know that the two expressions are equal to each other. So, we can write the equation:

[tex]5x-1=-6[/tex]

B)

Now, we can solve the equation for x. Add 1 to both sides:

[tex](5x-1)+1=(-6)+1[/tex]

The left will cancel. Add on the right:

[tex]5x=-5[/tex]

Finally, divide both sides by 5:

[tex](5x)/5=(-5)/5[/tex]

The left side will cancel. So, the value of x is:

A square has a perimeter of 4 yd. What is the length of each side?

Answers

the length of each side is one
add them together to get the perimeter of four

The length of each side of the square will be 1 yard.

What is the perimeter of the square?

A square has four equal sides, and four vertices, and is a closed, two-dimensional object. It has parallel sides on either side. A square is also equivalent to a rectangle with equal length and width.

The square's perimeter is four times as long as its side.

For a square with a side length of a unit, we get:

Perimeter of the square = 4a unit

A square has a perimeter of 4 yards. Then the length of each side of the square will be given as,

4 = 4a

a = 1 yard

The length of each side of the square will be 1 yard.

Answer:

  A. f(x)=56,000(0.93)x+8400

Step-by-step explanation:

The growth rate is -7%, so the growth factor will be 1 -7% = 0.93. This is the base of the exponential term.

The 8400 special passes will add 8400 visitors to the park in addition to those who pay the regular fee. Thus the number of visitors is ...

  f(x) = 56,000(0.93^x) +8400 . . . . matches choice A
