The mapping diagram shows a relation. A mapping diagram shows a relation, using arrows, between inputs and outputs for the following ordered pairs: (negative 6, 0), (2, 1), (negative 7, negative 4), (11, 2), (3, 2). What is the domain of the relation? {x| x = –4 , 0, 1, 2}. {x| x = –7, –6, 2, 11, 3}. {y| y = –4, 0, 1, 2}. {y| y = –7, –6, 2, 11, 3}.
Answers
Answer:
b
Step-by-step explanation:
The domain is a set of input values so {x| x = –7, –6, 2, 11, 3} will be the domain of the relation therefore option (B) will be correct.
What is the range and domain of a function?A function's range is the set of all values that the function accepts, and its domain is the set of all values for which the function is defined.
The domain is for the independent variable while the range is for the dependent variable.
For example f(x) = x²
Now if we put x = 1 then it is called as domain variable while the value of function at x = 1 its that f(1) = 1 called range variable.
The domain is the set of all input values where the function is defined.
Since in the given relation ;
All input values have an output so all input values will be the domain of the given relation.
Hence "{x| x = –7, –6, 2, 11, 3} will be the domain of the relation".

Step-by-step explanation:

AB = BC
-x + 25 = 3(2x - 8)
-x + 25 = 6x - 24
-7x = -49
x = 7
AC = 2(-x + 25) = 2(-7 + 25) = 2(18) = 36
AC = 36

Step-by-step explanation:
have a wonderful day! brainliest?
Answer:
B. (7)
Step-by-step explanation:
First, we figure out how many more items Joshua needs to sell so we do 20 - 6.
20 - 6 = 14.
Next, we do 14 / 2 because each customer buys 2 items.
14 / 2 = 7
Therefore, Joshua must have 7 additional customers to reach his goal.

Compare 1/2 and 5/7:
The simplest way is to ask if 5/7 is more than one half. Half of 7 is 3.5, and 5 is greater than 3.5, so 1/2 < 5/7.
The way that is a little more work is to get a common denominator and make equivalent fractions of 7/14 and 10/14.
Fraction to decimal of 4/5. 4 divided by 5 = 0.8
Decimal to fraction, 0.78:
0.78 = 78 hundredths = 78/100 as a fraction. They usually want fractions in the lowest terms, so divide the numerator and denominator by two, and you have 39/50.
Mixed to improper fraction 5 2/9: multiply the denominator of 9 times the whole number of 5, that equals 45. Add the 2 in the numerator, that is 47. Keep that over 9, because we are trying to figure out how many ninths we have. 5 2/9 = 47/9
Add ‘em 3/5 + 1/2:
Make equivalent fractions with a common denominator. (10 is the least/lowest common denominator). So we are adding 6/10 + 5/10 = 11/10 or 1 1/10.
Improper to mixed, 9/4:
We have 9 fourths. 4 fourths = 1 whole. So we get 2 wholes with 1/4 left over. 9/4 = 2 1/4.
Subtract ‘em, 3/10 - 1/5.
Again, need a common denominator/equivalent fraction. 1/5 = 2/10
3/10 - 2/10 = 1/10
Draw it, 1/3:
The circle is already divided into thirds. Shade one of them in.
Multiply ‘em 2/3 x 5:
Multiply the numerator times the whole number, leave the denominator alone. 2/3 x 5 = 10/3 = 3 1/3 if they want it converted to a mixed number.
Divide ‘em: 8/9 divided by 3 is 8/27
What’s the word?
4 x 1/2 = 2 (what is one half of 4?)
Word up:
3/5 divided by 3 = 1/5

Answers
Answer:
Greater than symbol.
2/3 > 2/4
Step-by-step explanation:
We have two fractions, 2/3 and 2/4
We then go back to the inequality part of mathematics where we have symbols such as greater than (>), less than (<), and equal to (=).
Of the three inequality symbols, we look and pick at the one that represents best, the fractions we were given.
2/3 and 2/4
With 2/3 being greater than 2/4.
2/3 = 0.67
2/4 = 0.50
Succinctly, 2/3 > 2/4.

The values of w is inversely proportional to m .If w=8 then m=25; what is m when w=20? Show me the steps please
Answers
Answer:
m = 10
Step-by-step explanation:
The values of w is inversely proportional to m
Mathematically:
w ∝ 1/m
w = k × 1/m
w = k/m
Where k is the Constant of Proportionality
Step 1
Solve for k
If w=8 then m=25
w = k/m
8 = k/25
Cross Multiply
k = 25 × 8
k = 200
Step 2
what is m when w=20? Show me the steps please
We solve for m
w = k/m
k = 200
20 = 200/m
Cross Multiply
20m = 200
m = 200/20
m = 10

Step-by-step explanation:
The remaining angle of the bigger triangle = 180 - 84.6 - 30.4 = 65 (angle sum of triangle)
The three angles are the same for both triangles
The triangles are similar to each other because the angle-angle theorem is satisfied.
What is the triangle?A triangle is a three-sided polygon with three angles. The angles of the triangle add up to 180 degrees.
The triangles are given.
Let the third angle of the triangle be x. Then we have
84.6° + 30.4° + x = 180
x = 65°
Then the triangles are similar to each other because the angle-angle theorem is satisfied.
Thus, the correct option is C.
