Answer:
The first element of a set which is linked with the element of second set is called domain.
The element of second set is known as range.
Answer:
When functions are first introduced, you will probably have some simplistic "functions" and relations to deal with, usually being just sets of points. These won't be terribly useful or interesting functions and relations, but your text wants you to get the idea of what the domain and range of a function are. Small sets of points are generally the simplest sorts of relations, so your book starts with those.
for example
State the domain and range of the following relation. Is the relation a function? {(2, –3), (4, 6), (3, –1), (6, 6), (2, 3)}
The above list of points, being a relationship between certain x's and certain y's, is a relation. The domain is all the x-values, and the range is all the y-values. To give the domain and the range, I just list the values without duplication:
domain: {2, 3, 4, 6}
range: {–3, –1, 3, 6}
(It is customary to list these values in numerical order, but it is not required. Sets are called "unordered lists", so you can list the numbers in any order you feel like. Just don't duplicate: technically, repetitions are okay in sets, but most instructors would count off for this.)
While the given set does indeed represent a relation (because x's and y's are being related to each other), the set they gave me contains two points with the same x-value: (2, –3) and (2, 3). Since x = 2 gives me two possible destinations (that is, two possible y-values), then this relation is not a function.

Answer:
Angle 1: 34°
Angle 2: 146°
Angle 3: 146°
Angle 4: 34°
Angle 5: 34°
Angle 6: 146°
Angle 7: 146°
Angle 8: 34°
Step-by-step explanation:
Angle 1: because angle 1 and 5 are corresponding, we know that angle 1 is 34°.
Angle 2: because a line is 180°, we can set angle 1 and 2 equal to 180° ( 34+x+15=180) which when solved, x = 131. but you need to plug it back into the equation of angle 2 to find out how many degrees it is. ( 131+15=146 ) So angle 2 is 146°
Angle 3: angles 2 and 3 are vertical angles, so angle 3 is 146°
Angle 4: angles 1 and 4 are vertical, so angle 4 is 146°
Angle 5: is given
Angle 6: angles 2 and 6 are corresponding so they are equal, angle 6 is 146°
Angle 7: angles 6 and 7 are vertical so angle 7 is 146°
Angle 8: angles 5 and 8 are vertical of each other so they are equal, angle 8 is 34°

A project manager estimates that a project will take
x hours to complete, where x > 100. The goal is for
the estimate to be within 10 hours of the time it will
actually take to complete the project. If the manager
meets the goal and it takes y hours to complete the
project, which of the following inequalities
represents the relationship
between the estimated
time and the actual completion time?

Subtract 7 from both sides:
[tex]-4x+7-7=11-7[/tex]

d(n) = 6 - 4(n - 1) find the 5th term in the sequence
d(n) = 6 - 4(n - 1)
Plug 5 into the equation for n.
d(5) = 6 - 4(5 - 1)
Subtract 1 from 5
d(5) = 6 - 4(4)
Multiply 4 by 4
d(5) = 6 - 16
Simplify the right side
d(5) = -10
The fifth term in the sequence is -10
The 5th term of the sequence is -10.
What is a sequence?A sequence is an enumerated collection of objects in which repetitions are allowed and order matters.
Given is a sequence, d(n) = 6 - 4(n - 1)
To find the 5th term, put n = 5
d(5) = 6-4(5-1)
= 6-4×4
= 6-16
= -10
Hence, the 5th term of the sequence is -10.

Answer:
61.37
Step-by-step explanation:
this is i believe the correct answer but i could still be wrong cause x times x is x square but i am not so sure how much that really matters
take x as the width
x plus 10 as the length
2x plus 10 equals 7544 squared
so square root 7544 minus 10 divided by 2
note that it must be done all at once u cant do it seperately
x is 61.37 dont forget to add 10

Answer:
The answer is
46 caloriesStep-by-step explanation:
In order to solve this question we use ratio and proportion
From the question there are 230 calories in 48g of M & M's
That's
If in 48g of M & M's we have 230 calories
9.6 g will contain

which value for x makes the sentence true? 1/40 + x = 1/8
Answer:
x = 1/10
Step-by-step explanation:
1/40 + x = 1/8
Subtract 1/40 from each side
1/40-1/40 + x = 1/8-1/40
x = 1/8 - 1/40
Get a common denominator
x = 1/8 *5/5 - 1/40
x = 5/40 - 1/40
x = 4/40
Simplify
x = 1/10

Answer:
x = 4.2
Step-by-step explanation:
72 + 10x = 114
10x = 114 - 72
10x = 42
x = 42/10
x = 4.2
Answer:
x = 4.2
Step-by-step explanation:
x is equal to 4.2 because ∠PQR and ∠RQS have a sum of 114° so if you subtract 72 from 114 you get 42. Now if you simply divide 42 by 10 you get 4.2.
