Answer: THE ANSWER IS

Determine if the relation is a function.

The relation is a function.

Find the domain and range.

Domain:

{−3, −1,  5,  8}

Range:

{−6}

Graph.

{(−3,−6),  (−1,  −6),  (5,  −6),  (8,  −6)}

Determine if the relation is linear.

The relation is linear

Find the inverse.

( − 6 ,  − 3 ) ,   ( − 6 ,  − 1 ) ,   ( − 6 ,  5 ) ,   ( − 6 ,  8 )

Step-by-step explanation: IT'S NOT A OR D.. ig

1:    Recall that a function  from a set  to a set  is a relation that assigns to each element  in the set  exactly one element in the set . The set  is the domain (or set of inputs) of the function and the set  contains the range (or set of outputs).

The general characteristics of functions are:

A. Each element in A must be matched with an element in B.

B. Some elements in B may not be matched with any element in A.

C. Two or more elements in A may be matched with the same element in B.

D. An element in A (the domain) can not be matched with two different elements in B.

________________________________________________

Solving this problem we have:

1. The mapping diagram is represented in Figure 1. As you can see this is a function. Each element in A is matched with an element in B. All the elements in A are matched with the same element in B. So, this fulfills with the definition of function.

2. The mapping diagram is represented in Figure 2. This is not a function. Notice that an element in A (the domain) is matched with two different elements in B, that is, -8 is matched with -6 and 1.

2:    #1) This is a function.

#2) This is not a function.

(The mapping diagrams are not present to match to these.)

Explanation:

A function is a relation in which each element of the domain is matched to no more than one element of the range; in other words, no x gets mapped to more than 1 y.

In #1, no x is mapped to more than 1 y, so it is a function. However, in #2, -8 is mapped to both -6 and to 1; this x is used more than once, so this is not a function.

4:    Answer:

Option D is correct.

The relation {(-8, -6) (-5, 2) (-8, 1) (7, 3)} is not a function.

Step-by-step explanation:

Given the relation:  {(-8, -6) (-5, 2) (-8, 1) (7, 3)}

Domain is the set of all possible inputs of a relation i.e { -8, -5 , -8 , 7}

Range is the set of output values of a function i.e, {-6, 2 , 1 , 3}

The mapping as shown below in the figure:

A function is a relation in which every element of the domain is matched to not more than one element of the range.

In other words, we can say that ,no value of x gets mapped to more than 1 value of y.

Since, from the mapping you can see that the domain value -8  paired with -6 and 1;  as x is used more than once.

Therefore, this relation is not a function

Answer:

72

Step-by-step explanation:

Answer:

72 degrees

Step-by-step explanation:

x = 360 - (108 + 121 + 59)

x = 360 - (108 + 180)

x = 360 - 288

x = 72 degrees

Hope that helps!

Actually Welcome to the Concept of the Ratio and Percentage.

Let the total salary be x, so we get as,

20 % of x = $700

hence, x would be,

(20/100)*x = 700

===> x = 70000/20

===> x = $3500

===> hence the total earning of them is $3500

Answer:

x=−2

y=7

Step-by-step explanation:

5x+2y=4

x−3y=−23

In order to solve by elimination, coefficients of one of the variables must be the same in both equations so that the variable will cancel out when one equation is subtracted from the other.

5x+2y=4,x−3y=−23

To make 5x and x equal, multiply all terms on each side of the first equation by 1 and all terms on each side of the second by 5.

5x+2y=4,5x+5(−3)y=5(−23)

Simplify.

5x+2y=4,5x−15y=−115

Subtract 5x−15y=−115 from 5x+2y=4 by subtracting like terms on each side of the equal sign.

5x−5x+2y+15y=4+115

Add 5x to −5x. Terms 5x and −5x cancel out, leaving an equation with only one variable that can be solved.

2y+15y=4+115

Add 2y to 15y.

17y=4+115

Add 4 to 115.

17y=119

Divide both sides by 17.

y=7

Substitute 7 for y in x−3y=−23. Because the resulting equation contains only one variable, you can solve for x directly.

x−3×7=−23

Multiply −3 times 7.

x−21=−23

Add 21 to both sides of the equation.

x=−2

The system is now solved.

x=−2,y=7

Answer:

1

Step-by-step explanation:

7m+19/2=13

7m +19 = 13 x 2

7m = 26 - 19

m = 7/7 = 1

Another way :

7m+19/2=13

7m = 26/2 - 19/2

7m = 7

m = 7/7 = 1

Both ways r correct !!

Answer:

[tex]x = \frac{-b \pm \sqrt{b^2 - 4ac}}{2a}[/tex]

Step-by-step explanation:

Hello!

Let's start with the given equation and work our way towards x.

Divide both sides by a

Move c/a to the other side

At the step, we have to use the Completing the Square method.

Multiply -c/a by 4a and add the two fractions

Square Root both sides

Subtract b/2a

And that's the derivation of the Quadratic Formula.

Answer:

a is greater than -2

Step-by-step explanation:

Solving a comparison like this is the same as solving an equation, except you need to watch out for the signs of numbers.

Given:

-2a - 12 < -8

The first thing we need to do here is to add 12 to both sides:

-2a - 12 + 12 < -8 + 12

-2a < 4

You'll notice we're just increasing both sides, so the relationship stays the same.

Now we divide both sides by -2.  Because the number is negative, it changes whether the result is greater or less.

-2a < 4

-2a ÷ -2 > 4 ÷ -2

a > -2

Giving us our final answer.

Answer:

x = 25

Step-by-step explanation:

A quadrilateral is inscribed in a circle, so it is a cyclic Quadrilateral.

Opposite angles of a cyclic quadrilateral are supplementary.

Therefore,

3x + 21y = 180°.....(1)

2x + 26y = 180°.....(2)

From equations (1) & (2)

3x + 21 y = 2x + 26y

3x - 2y = 26y - 21y

x = 5y

y = 1/5 x

Plug y = 1/5 x in equation (1)

3x + 21*1/5x = 180

15x + 21x = 180*5

(Multiplying both sides by 5)

36x = 900

x = 900/36

x = 25

Answer:

Step-by-step explanation:

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

Explanation:

Define the following events

We are given the following probabilities

Then we're further told that "if it is dry, then the probability someone will arrive on time is 4/5". We can condense that into the notation

P(T given D) = 4/5

The "given D" means that we know 100% that event D has occurred. So we're seeing how event T behaves because of D occurring. In other words P(T given D) is the same as saying "What is P(T) when we know D has happened?"

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

The instructions also mention that "If it rains, the probability someone is on time is 2/5" tells us we have the notation

P(T given R) = 2/5

And also, the probability someone is on time if it is snowy is

P(T given S) = 1/10

due to it saying "If it snows, the probability that someone will arrive on time is 1/10".

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

To recap so far, your teacher told you these three conditional probabilities

They are conditional due to the "given" as part of the probability. They depend on the given event happening.

Subtract each fraction from 1 and we end up with these complementary probabilities

I'm using the idea that P(A)+P(B) = 1, where A and B are complementary events. One or the other event must happen. Either you are on time, or you are late.

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

Recall the conditional probability formula is

P(A given B) = P(A and B)/P(B)

which rearranges to

P(A and B) = P(A given B)*P(B)

We'll use this idea to get the following

This means,

P(L) = P(L and D) + P(L and R) + P(L and S) ..... law of total probability

P(L) = 1/10 + 1/5 + 3/20

P(L) = 2/20 + 4/20 + 3/20

P(L) = (2+4+3)/20

P(L) = 9/20 is the probability someone is late

Answer:

x = 0, y = -4

Now plug it in:

y = mx + b

-4 = b

So the y intercept is -4

Answer:

R=15 1/6

Step-by-step explanation:

You can add 5 and 1/6 to each side so -5 1/6+5 1/6= 0 so it cancels out therefore on the other side of the equal side you add 5 1/6+10 to get 15 1/6.
