24. Which relation has a domain of {–5, –3, 0} and a range of {1, 2, 3, 4, 5, 6, 7, 8}?
A) {(2, –5), (3, –3), (6, 0), (7, –5), (1, 0), (8, –5), (4, –3), (5, 0)}
B) {(-5, -5), (-3, 0), (2, 8), (1, 7), (5, 3), (6, 4)}
C) {(–5, 8), (–5, 2), (–3, 3), (–3, 1), (0, 4), (0, 5), (–5, 7), (–3, 6)}
D) {(-5, 9), (10, –3), (2, 1), (3, 4), (0, 5), (6, 8), (0, 7)}
Answer:
Step-by-step explanation:
23 : C,D24: the domain is the set of all values of x, and the range are the input y
{(–5, 8), (–5, 2), (–3, 3), (–3, 1), (0, 4), (0, 5), (–5, 7), (–3, 6)}
It would be C1.11 People fit comfortably in a 5 feet by 5 feet area. Use this value to estimate the size of a crowd that is 5 feet deep on BOTH sides of the street along a 5-mile section of a parade route.
(4 Points)
Answer:
in 5ft by 5ft = 25ft^2, there can be 1 person
A normal street is 30ft wide
Then, if we want the width such that is 5 ft deep (from both sides)
Then we should subtract two times 5 ft:
30ft - 5ft - 5ft = 20ft.
Now the length is 5 miles
and 1 mile = 5280 ft
then 5 miles = 5*( 5280 ft) = 26,400 ft.
Then the area is:
20ft by 26,400 ft. =528,800 ft^2
And we know that in 25 ft^2 we can fit one person.
How many spaces of 25ft^2 we have in the 528,800 ft^2?
this is:
N = 528,800 ft^2/25ft^2 = 21,152
This means that in the street 21,152 people can fit comfortably.
The size of the crowd is 21,152 people.

what situations would solve by graphing be your preferred choice? Give an example.
In what situations would solve by substitution be your preferred choice? Give an example.
In what situations would solve by elimination be your preferred choice? Give an example.
Write a linear system that can be solved by any of the three methods.
Answer:
1) The solve by graphing will the preferred choice when the equation is complex to be easily solved by the other means
Example;
y = x⁵ + 4·x⁴ + 3·x³ + 2·x² + x + 3
2) Solving by substitution is suitable where we have two or more variables in two or more (equal number) of equations
2x + 6y = 16
x + y = 6
We can substitute the value of x = 6 - y, into the first equation and solve from there
3) Solving an equation be Elimination, is suitable when there are two or more equations with coefficients of the form, 2·x + 6·y = 23 and x + y = 16
Multiplying the second equation by 2 and subtracting it from the first equation as follows
2·x + 6·y - 2×(x + y) = 23 - 2 × 16
2·x - 2·x + 6·y - 2·y = 23 - 32
0 + 4·y = -9
4) An example of a linear system that can be solved by all three methods is given as follows;
2·x + 6·y = 23
x + y = 16

Write the set of all real numbers except 100 in set builder notation. PLEASE ANSWER FAST
Answer:
See below.
Step-by-step explanation:
The set of all real numbers except for 100 in set builder notation (assuming the variable is x) is:
[tex]\{x|x\in\mathbb{R},x\neq100\}[/tex]
The very first x represents the variable.
The second with the R represents the number. Here, we want all real numbers.
And the third is the constraint. We want all real numbers except for 100.

Phil weighs 120 pounds and is gaining ten pounds each month. Phil weighs 150 pounds and is gaining 4 pounds each month. How many months, m, will it take for Bill to weigh the same as Phil?
Answer:
5 months
Step-by-step explanation:
I'm assuming there was a typo and said that Phil weighed both amounts so I'm assuming that the second amount is Bill's weight
We can use LCM for this
So lets make a list for both of them
Phil:120, 130, 140, 150, 160, 170, 180, 190, 200
Bill: 150, 154, 158, 162, 166, 170, 174
As you can see here, after 5 months, they will have the same weight.
We can check our work to.
lets do 120+(10*5)=170
and 150+(4*5)=170
I hope this makes sense
Answer:
5 months
Step-by-step explanation:
lets chart it like i did as you can see they both started at 120 and 150 then 5 month later there both 170

Creating a Function from a Mapping The mapping shows a relationship between input and output values. Which ordered pair could be removed to make this relation a function? Input Output O (-5, 0) O (-1, -3) -5 O (4, -2) 2 -3 O (6,-1) -1 -2 ī ņ ņ na v v • 4 2 6
I'm not sure what some of the ordered pairs are in what you wrote, but a function is when each input has one output. So, for every x there is one y. The x values can not repeat. So, remove one of two ordered pairs where the x value is repeating.
What are the two solutions to the absolute value equation |2x+3|=7
Step-by-step explanation: We can solve the equation |2x + 3| = 7 by
first splitting things up into two separate equations.
The first equation will look just like the original problem,
minus the absolute value signs and we have 2x + 3 = 7.
The second equation will look just like the first, only the right
side will be changed to a negative and we have 2x + 3 = -7.
Now solve each equation from here.
In our first equation, subtract 3 from both sides to get 2x = 4.
Then divide both sides by 2 and x = 2.
In our second equation, subtract 2 from both sides to get 2x = -10.
Now, divide both sides by 2 and we have x = -5.
So either x = 2 or x = -5.

Comelia and Christopher are arguing about Real Number (R) Sets. Comelia says that all Whole (W) numbers are Rational (Q) and Christopher

====================================================
Explanation:
We're told that "Christopher says that all Rational (Q) numbers are Whole (W)", which makes Christopher not correct. Some rational numbers are whole numbers. For instance, the number 7 = 7/1 is rational and it's a whole number as well.
However something like 1/2 is rational, but it's not a whole number. A whole number doesn't have any fractional or decimal part to it. It can be thought of the number of something.
Comelia is correct because all whole numbers are rational. If x is some whole number, then x = x/1 is rational as well. Replace x with any whole number you want. Her statement does not work in reverse as shown above.
When drawing a Venn diagram, the circle for "whole numbers" will be entirely inside the circle for "rational numbers", and not the other way around.

What is an expression?Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.
Since, We know that;
The neurons are the structural and functional system of nervous system. It is composed of parts such as:
Dendrites – Branched structure located at the terminal of the cell body.
Cell body – It contains nucleus.
Nucleus – It is the controlling center of the cell.
Axon – Transports the signals from cell body to synapses.
Synapses – Sends the signal from one neuron to another neuron.
Thus, “Neurons are building blocks of nervous system. They process and transmit signals.”
“In a neuron, the nucleus is found inside cell body”.

Answer:
Step-by-step explanation:
PLEASE HELP BRAINLIEST FOR WHOEVER ANSWERS CORRECTLYYYYYYYYYYYYYYY the perimeter P of a square is four times the length of one side s, which can be expressed as P = 4s. is (13,51) a solution of this equation? if not, find a solution that uses one or the other of the given values
Answer:
No, but (13,52) is
Step-by-step explanation:
To find this you need to understand what (13,51) means.
13 = x coordinate
51 = y coordinate
If you plug 13 into the equation given (P = 4s) you get 52. Therefore, (13,51) is not a solution but instead (13,52) is.
This means each of the four sides has a length of 13 units.
I hope this helps!
-TheBusinessMan
Answer:
P = 52
Step-by-step explanation:
51 = 13(4) 13x4=52
51 does not equal 52 there fore those values are immensely incorrect. However you may state 52 as the perimeter therefore allowing 52 1to equal 13(4).
New solution 52 =13(4)
