Answer:

Graph on the top right.

Step-by-step explanation:

A function is a relation where one domain value is assigned to exactly one range value.

In a table, there would be no values repeating in the x-column.

The graph on the top right does not repeat any x values. Therefore, it is a function.

Why the other options are not functions:

Answer:

The reasonable domain is less extensive that the mathematical domain.

Step-by-step explanation:

The reasonable domain for the function is the set of all possible values of the independent variable (in this case x) that make sense to the situation in which the function is being applied.

For the function [tex]f(x)=16.4x+2[/tex], the mathematical domain is the set of real numbers.

Now, in the function the independent variable ''x'' represents the distance (in miles) between the job site and the office. We know that we can't have a negative distance in real life. Therefore, we need to restrict our mathematical domain into the reasonable domain by eliminating all the negative numbers from the set of all real numbers.

Our new domain (reasonable domain) is

{x ∈ IR : x ≥ 0}

The reasonable domain is less extensive that the mathematical domain.

Answer:

24.5

Step-by-step explanation:

If you multiply 2 and 24.5 together you would get 49

The value of the solution to the given equation is 7, which is the correct answer that would be option (D).

The term "equation" refers to mathematical statements that have at least two terms with variables or integers that are equal.

The equation is given in the question following as:

x² = 49

We have to determine the value of the solution to the given equation

As per the given question, we have

⇒ x² = 49

⇒ x² - 49 = 0

⇒ x² - 7² = 0

We know that the formula as, a² - b² = (a + b)(a - b)

Here a = x and b = 7, and we get

⇒ (x + 7)(x - 7) = 0

⇒ x + 7 = 0 and x - 7 = 0

⇒ x = - 7 = 0 and x = 7

Thus, the value of the solution to the given equation is 7,

Hence, the correct answer would be an option (D).

Answer 2/3

Step-by-step explanation:

Answer:

x = Y-3 over 8

Step-by-step explanation:

Y = 8x+3

Take the 3 to the other side by subtracting it

so:

Y-3 = 8x

divide 8 to get only x

x = Y-3 over 8

Step-by-step explanation:

2 x (16 + (10 + 3) - 3) - 22

2 x (16 + 13 - 3) - 22

2 x 26 - 22

2 x 4

= 8

Answer:

-3/2

Step-by-step explanation:

The average rate of change is synonymous to the slope.

So, to find the average rate of change from the interval x=-2 to x=2, first find the y-values at x=-2 and x=2.

At x=-2, we can see that y is 4. Thus, we have (-2,4).

At x=2, we can see that y is -2. Thus, we have (2,-2).

Now, use the slope formula. The formula for slope is:

[tex]m=\frac{y_2-y_1}{x_2-x_1}[/tex]

Let (-2,4) be x₁ and y₁ and let (2,-2) be x₂ and y₂. Therefore:

[tex]m=\frac{-2-4}{2--2}[/tex]

Simplify:

[tex]m=\frac{-6}{4}[/tex]

Reduce:

[tex]m=-3/2[/tex]

So, our average rate of change from the interval x=-2 to x=2 is -3/2.

Answer:

1363.6

Step-by-step explanation:

let the basic salary be = x

10% of x = 10/100x

So the equation = x + 10/100x = 1500

                           = x + 0.1x = 1500

                           = 1.1x = 1500

                           =  x = 1500/1.1

                           =  x = 1363.6

Answer: the answer is when the wheel is at 70.43° after 7.82seconds from when you ride on it

Step-by-step explanation:

Rule of 3

65ft center meaning the top point at 90° will be at 115ft since the diameter of the wheel is 50ft

If the 90° gets you at 115ft, at what degree will you reach 90ft?

90°----115ft

X°------90ft

(90x90) ÷ 115 = 70.43°

Then if 360° takes 40seconds which is the complete turn

360°----40s

70.43°--X

(70.43 x 40) ÷ 360 = 7.82s

===================================================

Explanation:

First focus on the fact that "the average of x and t is y". This means

(x+t)/2 = y

We basically add x and t, then divide by 2 to get the average y

--------

We are then told that s = 2y, so we double the average

s = 2y

s = 2(x+t)/2

s = x+t .... notice the 2's cancel each other out when dividing

s turns out to be the sum of x and t, which is fitting I think

---------

Now find the average of s, x, and t. You'll add the three values and divide by 3

(s+x+t)/3

(s + (x+t))/3

(s + s)/3 .... replace x+t with s

2s/3

2(2y)/3 ... plug in s = 2y

4y/3

The average of s, x, and t in terms of y is 4y/3. The correct option is D. 4y/3

From the question, we are to determine the average of s, x, and t in terms of y

From the given information

The average of x and t is y

That is,

(x+t)/2 = y

∴ x + t = 2y

Also,

s = 2y

The average of s, x, and t is

(s + x + t) / 3

Putting the values of x + t and s into the above expression, we get

(2y + 2y)/3

This becomes

4y/3

Hence, the average of s, x, and t in terms of y is 4y/3. The correct option is D. 4y/3

Answer in fraction form = 1/20

Answer in decimal form = 0.05

Answer in percent form = 5%

These are three ways to express the same thing

=============================================================

Explanation:

Assume the gumball machine only has 5 gumballs, one of each color. The probability of getting yellow is 1/5 since there is one that is yellow out of 5 total.

The probability of getting a lion rubber band is 1/4 for similar reasoning as above.

Because the two events (getting yellow, getting a lion) are independent, this means we can multiply the two probabilities to get (1/5)*(1/4) = 1/20

Use your calculator to see that 1/20 = 0.05 which converts to 5% when you move the decimal point over 2 spots to the right.

You are multiplying each calculation by 2 because a rectangular prism has 6 sides. 2 sides height x width, 2 sides height x length, and 2 sides width x length

Answer:

x=2 is the answer.

Step-by-step explanation:

Subtracting 10 on both sides to find out the value of x

Answer:

2167.2

Step-by-step explanation:

Answer:

2167.2

Step-by-step explanation:

For this problem, let's use the distributive property to make this multiplication easier.

4.2 can be redistributed into 4 & 1/5, as 0.2 == 1/5.

Now let's multiply these numbers with 516.

(516 * 4) + (516 * 1/5) == ?

(2064) + (103.2) == ?

2167.2 == ?

So the product of 516 and 4.2 is equal to 2167.2.

Answer:

n = 0 or n = -9/16

Step-by-step explanation:

Solve for n:

2 (8 n^2 + 9 n) - 9 n = 0

Hint: | Write the quadratic polynomial on the left hand side in standard form.

Expand out terms of the left hand side:

16 n^2 + 9 n = 0

Hint: | Factor the left hand side.

Factor n from the left hand side:

n (16 n + 9) = 0

Hint: | Find the roots of each term in the product separately.

Split into two equations:

n = 0 or 16 n + 9 = 0

Hint: | Look at the second equation: Isolate terms with n to the left hand side.

Subtract 9 from both sides:

n = 0 or 16 n = -9

Hint: | Solve for n.

Divide both sides by 16:

Answer: n = 0 or n = -9/16
