Which of the following best defines an input? (4 points)
a
An input is the result of a relation or the function rule, usually the y-values in a set of ordered pairs or on a table or graph.
b
An input is a special type of relation for which there is a rule that pairs each input with exactly one output.
c
An input is a set of ordered pairs in which no y-value repeats.
d
An input is the value that determines another based on the relation or the function rule, usually the x-values in a set of ordered pairs or on a table or graph.
Answer:
d
Step-by-step explanation:
hope this helped!!!!!
Answer: d
An input is the value that determines another based on the relation or the function rule, usually the x-values in a set of ordered pairs or on a table or graph.
Step-by-step explanation: Its d because the function has one output for each input so d is the correct answer.
I also saw the question on a different persons test in brainly and it was d.

Ms. Van Tress has 134 students. She sees 38 students before lunch and 96 students after lunch.
What percentage of her students does she see before lunch? After lunch? (Round your answers to
the nearest whole number percent)
Answer:
[tex]\%Percent = 28\%[/tex] ---- Before Lunch
[tex]\%Percent = 72\%[/tex] --- After Lunch
Step-by-step explanation:
Given
[tex]Total = 134[/tex]
[tex]Before\ Lunch = 38[/tex]
[tex]After\ Lunch = 96[/tex]
Required
Determine the percentage of students seen in both cases.
This percentage is calculated by dividing the number of students seen by the total number of students. Then multiplied by 100%
i.e
[tex]\%Percent = \frac{Seen}{Total} * 100\%[/tex]
- Before Lunch;
[tex]\%Percent = \frac{Before\ Lunch}{Total} * 100\%[/tex]
[tex]\%Percent = \frac{38}{134} * 100\%[/tex]
[tex]\%Percent = \frac{3800\%}{134}[/tex]
[tex]\%Percent = 28\%[/tex] --- approximated
- After Lunch;
[tex]\%Percent = \frac{After\ Lunch}{Total} * 100\%[/tex]
[tex]\%Percent = \frac{96}{134} * 100\%[/tex]
[tex]\%Percent = \frac{9600\%}{134}[/tex]
[tex]\%Percent = 72\%[/tex] --- approximated
please help!! which triangle is similar to ABC?
A. Triangle A
B. Triangle B
C. Neither
D. Both
Answer:
triangle A because the measurements would be the same. If you add 30 + 112, you get 150. Triangles add to 180, so the missing angle of the first one is 30.
this means triangle A has the same measurements as ABC

Given: P is a point on the perpendicular bisector, I of MN.
Prove: PM = PN
Answer:
Step-by-step explanation:
I can't make specific statements about the proof because the midpoint is missing.
Givens
There are two right angles created by where the perpendicular bisector meats MN. Both are 90 degrees.
MN is bisected by the point on MN where the perpendicular meets MN
The Perpendicular Bisector is is common to both triangles.
Therefore the two triangles are congruent by SAS
PM = PN Parts contained in Congruent triangles are congruent.
19 more than 9 times a number is less than or equal to 163. Which of the following represents the solution set of this problem?
Answer:
x ≤ 6
Step-by-step explanation:
Let the unknown number be x;
9 times the number is expressed as 9x
9 more than 9 times a number is expressed as 9x + 9
9 more than 9 times a number is less than or equal to 163 is then expressed as;
9x + 9≤ 63
≤ is the less than or equal to sign
Find the solution;
9x ≤ 63 - 9
9x≤54
x ≤ 54/9
x≤ 6
Hence the required solution is x ≤ 6
You and your family enjoy baking Christmas cookies together. Last year, you baked 120 cookies to pass out to friends and family. However, since you are unable to share cookies this year, you made 60% less cookies. How many total cookies did you make this year? First person to anwser correctly, gets brainleist!
Answer:
We can make 48 cookies.
Step-by-step explanation:
60 percent of 120 = 72
120 - 72 = 48

Apply the distributive property to factor out the greatest common factor. 90+27= equals
Answer:
1.
90+27
2.
90 = 9 x 10
3.
27 = 9 x 3
4.
So apply the distributive property would be:
90 + 27 = 9(10 + 3)
Step-by-step explanation:
Answer:
The greatest common factor of 90 and 27 is 9.
Using the distributive property , you could write: 9(10 + 3)

STEAM: The boiling pint of water is affected by changes in elevation. Use the expression of -2A/1000 where a represents the altitude in feet to find the number of degrees Farenhite at which the boiling point of water changes at altitude 5,000 feet
A) -10°F B) 20°F C) 10°F D) -20°F
Answer:
A) -10°F
Step-by-step explanation:
Given that:
Boiling point of water gets affected when there is a change in the elevation.
Expression to represent the temperature i.e. boiling point w.r.to altitude [tex]A[/tex] is given by the equation:
Temperature in [tex]^\circ F[/tex] = [tex]\frac{-2A}{1000}[/tex]
Given that, the altitude, [tex]A[/tex] = 5,000 feet
To find:
The number of degrees Farenhite at which the boiling point of water will change.
Solution:
Here, we are given the expression:
Temperature in [tex]^\circ F[/tex] = [tex]\frac{-2A}{1000}[/tex]
And value of altitude, [tex]A[/tex] = 5,000 feet
Let us put the value of [tex]A[/tex] in the equation and let us find the value of temperature in [tex]^\circ F[/tex].
Temperature in [tex]^\circ F[/tex] =
[tex]\frac{-2\times 5000}{1000}\\\Rightarrow -2\times 5\\\Rightarrow \bold{-10^\circ F}[/tex]
Therefore, the answer is:
A) -10°F

Step-by-step explanation:
Value of the exterior angle is equal to the addition of the opposite interior angles in a triangle
[tex]19 + 20 = 6x - 3 \\ 39 = 6x - 3 \\ 39 + 3 = 6x \\4 2 = 6x \\ \frac{42}{6} = \frac{6x}{6} \\ x = 7[/tex]
Jeremiah is also ordering comic books online. The equation y = 8x + 4 represents the total cost, y, including shipping for ordering x number of comic books. What is the cost of 20 comic books?
Answer:
[tex]y = 164[/tex]
Step-by-step explanation:
Given
[tex]y = 8x + 4[/tex]
Where
[tex]x = number\ of\ comic\ books[/tex]
[tex]y = total\ cost[/tex]
Required
Find y when x = 20
To do this, we simply substitute 20 for x in [tex]y = 8x + 4[/tex]
[tex]y = 8*20 + 4[/tex]
[tex]y = 160 + 4[/tex]
[tex]y = 164[/tex]
Hence, 20 comic books cost 164

Write the equation of the line that passes through the points (-7,1) and (7,-6).
Put your answer in fully reduced point-slope form, unless it is a vertical or horizontal
line.
Answer:
y-1=-1/2(x+7)
Step-by-step explanation:
Find the slope first using the slope formula.
y2-y1/x2-x1
-6-1/7--7
-7/14
Slope is -1/2
Now choose one of the coordinates and put it in point-slope form.
y-1=-1/2(x+7)
