Answer:
Proportional: second and third, non-proportional: first and fourth
Step-by-step explanation:
Proportional relationships are linear functions that pass through the origin. Using this definition, we can conclude that the proportional relationships are the second and third options whereas the non-proportional relationships are the first and fourth options.
Answer:
proportional relationship: the second one and the third one the first and the fourth one
Non-proportional relationship: the first and the fourth one
Step-by-step explanation:
Like the first person said, a proportional relationship is when a linear line passes thru the origin, which is known as (0,0), so the second and the third are the only ones that do that, plus they have a y-intercept of a 0 and the others don't.

Answer:
Slope = 0Step-by-step explanation:
The slope of a line between two points can be found by using the formula
[tex]m = \frac{y2 - y1}{x2 - x1} [/tex]
where
(x1 , y1) and (x2 , y2) are the points
From the question the points are
(5,–10) and (-3,-10)
Their slope is

There are 7 students in a class. If there are 3 seats in the front row, how many ways can the students sit in the front row, assuming there are no empty seats?
Answer:
35 different waysStep-by-step explanation:
Since there are 7 students in a classroom to fill a front row containing 3 seats, we will apply the combination rule since we are to select 3 students from the total number of 7 students in the class.
In combination, if r objects are to be selected from a pool of n objects, this can be done in nCr number of ways.
nCr = n!/(n-r!)r!
Selecting 3 students from 7 students to fill the seats can therefore be done in 7C3 number of ways.
7C3 = 7!/(7-3)!3!
7C3 = 7!/(4)!3!
7C3 = 7*6*5*4!/4!*3*2
7C3 = 7*6*5/6
7C3 = 7*5
7C3 = 35
Hence there are 35 different ways that the student can sit in the front assuming there are no empty seats.

why is it important that the real numbers have the property of being complete
Answer:Real numbers must be complete in order to fill the number line.
Step-by-step explanation: No steps I got this answer from my algebra notes.
Completeness as a property of real numbers ensures that the limit of a sequence exists within the set due to the absence of gaps or missing points
Completeness of real numbers means that there are no gaps in between a sequence of real numbers or on a real number line.
The importance of completeness of real numbers is of particular importance in other to ensure that mathematical calculations and analysis hold for all sequence of real numbers in a set.
With the presence of gaps or holes in real numbers, then the limit of a sequence of real numbers may not exist within a specified set.

Researchers recorded that a group of bacteria grew from 200 to 1,000 in 8 hours. At this rate of growth, how many bacteria will there be in 20 hours from the start of the experiment
Answer:
11,180
Step-by-step explanation:
The usual assumption for organic growth is that it is exponential. Here, the number increased by a factor of 1000/200 = 5 in 8 hours. For t in hours, a model for population might be ...
b = (initial value)·(growth factor)^(t/(period of growth))
b = 200(5^(t/8))
Using t = 20, the predicted population is ...
b = 200(5^(20/8)) = 200·5^2.5 ≈ 11,180
There might be about 11,180 bacteria in 20 hours.
Answer:

Given T(x,y)=(x+5,y+4) and the point P(2,3), what is T(P)?
==============================================
Explanation:
T(P) is the notation applying the translation rule T(x,y) = (x+5, y+4) to the point P(2,3)
The x+5 means we add 5 to the x coordinate of P. We have x = 2 become x+5 = 2+5 = 7. The point P shifts 5 units to the right to go from (2,3) to (7,3)
Then the point shifts 4 units up to arrive at (7, 7). We shift 4 units up due to the y+4 in the translation rule.
Or put another way, y = 3 is the y coordinate of P. So y+4 = 3+4 = 7 is the new y coordinate.

A hypothesis is:_______
a. a testable prediction about the relationship between variables.
b. a simple explanation for a psychological finding.
c. an observed relationship between independent and dependent variables.
d. an unprovable assumption about psychological processes.
Answer:
a. A testable prediction about the relationship between variables
Step-by-step explanation:
A hypothesis is the FIRST step in conducting research or experimenting. In other terms, a scientific guess based on limited knowledge. Contrary to our hypothesis, conclusion comes last in researching and states the summary of the information gathered.
The reason why it isn't letter D is because a hypothesis's provability can only be determined once you have your conclusion, which is after you have conducted a research or experiment.
The letters B and C are too unrelated to what an hypothesis is.

Answer:
Yes and closed interval
Step-by-step explanation:
The computation is shown below:
For the sum and the reciprocal as small as the possible equation is as follows
[tex]\(\frac{d}{dx}\left(x+\frac{1}{x}\right)=0.\)[/tex]
Now take out the derivates,
So,
[tex]\(1-\frac{1}{x^2}=0,\)[/tex]

The equation x + 2 = [tex]\sqrt{3x + 10}[/tex] is of the form x + a = [tex]\sqrt{bx + c}[/tex], where a, b, and c are all positive integers and b > 1. Using this equation as a model, create your own equation that has extraneous solutions. (Hint: Substitute 7 for x, and choose a value for a. Then square both sides so you can choose a, b, and c that will make the equation true.) (I know this is a handful but I'm really in need of help right now, thanks to everyone in advance!)
Answer:
Extraneous solution for Equation x + 1 = √7x + 15 : x = - 2
Step-by-step explanation:
We are given the equation x + a = √bx + c. As the hint says, let's substitute 7 for x first, receiving the following equation.
7 + a = √7b + c
Now let's say a = 1 and c = 8. Through substitution we solve for b,
7 + 1 = √7b + 8
8 = √7b + 8
8² = (√7b + 8)²
64 = 7b + 8
7b = 64 - 8 = 56
b = 56 / 7 = 8
Therefore, the equation x + 1 = √8x + 8 ( substitute the value of b ) will have a solution of x = 7. Let's simplify this equation and see if we receive any extraneous solutions.
x + 1 = √8x + 8
(x + 1)² - (√8x + 8)² = 0
(x + 1)² - 8x + 8 = 0
(x + 1)² - 8(x + 1) = 0
(x + 1)(x + 1 - 8) = 0
(x + 1)(x - 7) = 0
x = - 1 and x = 7
We already know that x = 7, but x = - 1 is not an extraneous solution. Therefore let's simplify the equation x + 1 = √7x + 15 and see if we receive any extraneous solutions.
(x + 1)² - (√7x + 15)² = 0
(x + 1)² - 7x + 15 = 0
x² - 5x - 14 = 0
(x - 7)(x + 2) = 0
x = 7 and x = - 2
In this case x = - 2 is an extraneous solution. We can check by substituting it back into the equation x + 1 = √7x + 15.
- 2 + 1 = √7(- 2) + 15
- 1 = √- 14 + 15
- 1 = √1
- 1 ≠ 1 - hence proved that x = - 2 is our extraneous solution
The equation with extraneous solution is [tex]x +5 = \sqrt{6x + 4[/tex]
The equation is given as:
[tex]x + 2 = \sqrt{3x + 10[/tex]
The form of the equation is given as:
[tex]x +a = \sqrt{bx + c[/tex]
Now, we assume that x = 7.
So, the equation becomes
[tex]7 +a = \sqrt{7b + c[/tex]
Assume that the value of a is 5
[tex]7 +5 = \sqrt{7b + c[/tex]
Add 7 and 5
[tex]12 = \sqrt{7b + c[/tex]
Square both sides of the equation
[tex]144= 7b + c[/tex]
Assume that the value of b is 6.
So, the equation becomes
[tex]144= 7(6) + c[/tex]
[tex]144= 42 + c[/tex]
Assume that c is 4
[tex]144= 42 + 4[/tex]
[tex]144= 46[/tex]
The above equation is false because 144 does not equal 46.
The values of a, b and c that makes the equation false are:
[tex]a=5[/tex]
[tex]b = 6[/tex]
[tex]c = 4[/tex]
So, we have:
[tex]x +a = \sqrt{bx + c[/tex]
[tex]x +5 = \sqrt{6x + 4[/tex]
Hence, the equation with extraneous solution is [tex]x +5 = \sqrt{6x + 4[/tex]

A zookeeper has 858585 treats to divide evenly among 888 seals. The zookeeper divides to see how many treats to give to each seal. The zookeeper will have as few treats left as they can.
Answer: 10 treats per seal, and there are 5 treats left.
Step-by-step explanation:
The zookeeper has 85 treats, and want to divide them into seals, in such a way that the treats left is minimized,
Then we want to find the multiple of that is closer to 85 (from below)
We know that: 8*10 = 80 is a multiple of 8, and the next one is:
8*11 = 88, but this is larger than 85, so we discard this option.
Then we will divide 80 treats into 8 seals, and we will have:
85 - 80 = 5 treats left.
Then each one of the 8 seals gets:
80/8 = 10 treats.
is x^2+y^2=5 a function? why or why not?
Answer:
No.
Step-by-step explanation:
A function must past the Vertical Line Test. We know that our equation x² + y² = 5 is a circle, and so some x-values have the same y-values, etc. Since not every x-value has its own y-value, our equation is not a function.
We can see this using a graph:
Since the vertical line test passes 2 points with the same x-value, it is not a function.
