In order to plot a set of coordinates on a graph page, you would need to take account of every pair of x and y values provided. The line that goes horizontally is the x-axis (from left to right). All the negative values move from point zero (the origin).

The ordered pair, or the coordinates tells you where x and y intersect. For example, the first set of coordinates are (2, 9). That means, when x is 2, then y is 9.

Observe that x equals 2 on the right side of the horizontal axis. Next, you look for the spot where y equals 9.

Next step, you carefully trace the spot where x is 2, and trace it up a straight line and at the point where y equals 9 (at the upper part of the y axis), you put a tiny "X" to mark the spot where both values intersect.

Notice that while tracing from x, you move upwards, and while tracing from y, you move towards the right. That point defines the coordinates (2, 9) which is the first line on your table.

You follow a similar step for every one of the other coordinates, which are;

Please note that I've just attached the same graph, but this time I've labelled the points one by one.

We have to determine which relation is a function.

What is the function?

A function from a set X to a set Y assigns to each element of X exactly one element of Y. The set X is called the domain of the function and the set Y is called the codomain of the function. Functions were originally the idealization of how a varying quantity depends on another quantity.

The relation between the function is

X cannot repeat itself

To know the length of the railing from point A to point B you can use Pythagoras Theorem.

You draw a right triangle:

You use the given information to know the measure of the legs in the triangle:

You can see that the value of x is the height of 5 steps: 5(7.5 in).

Then:

The B is equal to the lenght of 10 steps: 10(9.5in):

Then:

You have the next triangle:

You use the Pythagoras Theorem to find the h:

If the point (4, -1) is a point on the graph of f, then f(4) = -1

First blank = 4

second blank = -1

The given point: (4, -1)

From the point: the coordinate tells us x = 4, y = -1

For a graph of function f, f(x) is the same as y

To represent the point (4, -1) as a funtion of x (that is f(x)), we will replace x in f(x) with the value of the x coordinate. The result when we replace it will the value of the y coordinate

when x = 4

f(4) = the value of the y coordinate

f(4) = -1

To complete the blanks:

If the point (4, -1) is a point on the graph of f, then f(4) = -1

First blank = 4

second blank = -1

The total number of people that drove to the meeting is 240

80% drove to the meeting

Let the total number of people who attended the meeting be x

Using the percentage and whole relationship

Part = percentage x whole

whole = x

part = 240

percentage = 80%

240 = 80/100 * x

240 = 0.8x

Divide both sides by 0.8

240/0.8 = 0.8x/0.8

x = 300

The total number of people that attended the meeting is 300

The equation that represents the total cost is C = $400 + $125p .

The equation that represents the total cost is a function of the fixed cost and the variable cost. The fixed cost remains constant regardless of the level of output. The variable cost changes with the level of output.

Total cost = fixed cost + total variable cost

Total cost = fixed cost + (variable cost x total output)

C = $400 + ($125 x p)

C = $400 + $125p

Total cost when 0 phones are made =  $400 + $125(0) = $400

Total cost when 1 phone are made =  $400 + $125(1) = $525

Total cost when 2 phones are made =  $400 + $125(2) = $650

Total cost when 3 phones are made =  $400 + $125(3) = $775

The sum of all interior angles of a triangle is 180° thus the measure of the exterior angle to ∠D is 126° so option (D) is correct.

A triangle is a 3-sided shape that is occasionally referred to as a triangle. There are 3 sides and three angles in every triangle, some of which may be the same.

It is known that the sum of all three angles inside a triangle will be 180°.

So,   m∠D +  m∠E +  m∠F = 180°

(3x + 27) + (4x + 22) + 68 = 180

7x + 49 + 68 = 180

7x = 63

x = 9

So,  m∠D = (3(9) + 27)° = 54°.

The exterior angle of D = 180- 54 = 126°.

Hence "The sum of all interior angles of a triangle is 180° thus the measure of the exterior angle to ∠D is 126°".

m(4) = 110° due to the Transitive Property.

The Transitive Property states a that if a = b and b = c, then a = c.

m(3) + m(4) = 180 due to the definition of Supplementary Angles. All supplementary angles add up to 180°.

m(3) = 70° because 180 - 110 = 70.

The equation of the line perpendicular to the given equation is;

Option C is the correct answer

Here, we want to select which of the equations in the option is perpendicular to the given equation

Firstly, we need to understand that for two equations to be perpendicular, then the product of their slopes must be equal to -1

Before we proceed to compare, we need to write the equation in the general form

The equation of the line written in the general form will be;

where m represents the slope and the term b represents the y-intercept

Now, let us proceed to write the equation in the standard form;

We have this as;

Compared with the general form, we can see that the slope of this line is -2/3

Now let us get the slope of the line that would be perpendicular to it;

Now, the equation perpendicular to what was given will have a slope of 3/2

Fortunately, all the options in the question have been written in the general form

The one with a slope of 3/2 is option C

Answer:

f(x) = -∞ as x → ±∞

Explanation:

The given function is

f(x) = -x² - 4

To know the end behavior, let's replace x by a greater number and by a smaller number, so

If x = 100

f(x) = -100² - 4

f(x) = -10000 - 4

f(x) = -10004

If x = -100

f(x) = -(-100)² - 4

f(x) = -10000 - 4

f(x) = -10004

So, we can see that no matter if x is negative or positive, the value of f(x) will be positive. Then, we can say that the end behavior is

f(x) = -∞ as x → ±∞

The probability of a candy when randomly taken is purple or not red is 0.235

Given,

Number of red candies in the bag = 42

Number of green candies in the bag = 42

Number of yellow candies in the bag = 20

Number of purple candies in the bag = 32

We have to find the probability of a candy when randomly taken is purple or not red.

Probability, P(E) = Number of favorable outcomes / Total number of favorable outcomes

Here,

Number of favorable outcomes = 32

Total number of favorable outcomes = 42 + 42 + 20 + 32 = 136

So,

P(E) = 32/136 = 0.235

We have 9 boy kittens and 6 girl kittens, a total of 15 kittens.

9 cats will be selected and we have to calculate the probability that 5 boy kitttens and 4 girl kittens are chosen.

We could have modeled as a binomial experiment, but the probability of choosing a boy kitten is not constant after each selection. Then, we have to select an alternative method.

We can think of it of a combinatorial problem.

In this case, it is a combination problem, as the order of selection does not matter and each kitten is equivalent within its category.

Repetition is not allowed: a kitten selected can not be selected again.

We can start finding all the possible combinations for 9 kittens out of the total 15 kittens:

The probability of selecting 5 boys and 4 girls will be the relation between the outcomes where there are 5 boys and 4 girls and the total number of outcomes we have just calculated.

Then, we can now calculate how many combinations of 9 kittens have 5 boys and 4 girls as a product of two combinations: the combinations for the boys C(9;5) and the combinations for the girls C(6;4).

We can calculate this as:
