explain why not all solutions represented by inequation are always possible solutions in reality.
Why aren't all solutions to an inequality possible in reality?
(TL;DR at the bottom, but the full explanation is better)
Let's answer this using an example.
The equation 2x + 5 > 10 can represent a lemonade stand's sales. What do each of the numbers represent in a real-life situation?
x represents the amount of lemonade glasses sold 2 (dollars) represents the price of each glass of lemonade5 represents the base profit that the stand opened with10 represents the goal for profitA solution for this equation would be x = -3:
2x + 5 > 10
2(-3) + 5 > 10
6 + 5 > 10
11 > 10 - True
Another solution is x = 11/3:
2x + 5 > 10
2(11/3) + 5 > 10
(22/3) + 5 > 10
(37/3) > 10
(36/3)+(1/3) > 10
12 and (1/3) > 10
These are solutions to our inequality from a mathematical standpoint but are both implausible in real life.
Assuming that reasonable would mean a full glass, -3 and (11/3) are possible answers, but can't be reasonably sold. -3 glasses of lemonade can't be sold, and neither can (11/3) of a glass of lemonade.
Therefore, these values create a situation where "not all solutions represented by inequation are always possible solutions in reality."
TL;DR:
Not all solutions are possible because the value that makes the inequation true is not reasonable or feasible under realistic circumstances, such as a fraction value for people or a negative value for possession.

What type of transformation happened from (x,y) --> (-x,y)?
-----
A.Rotation 90*
B.Reflection over the y-axis
C.Translation left 1
D.Reflection over the x-axis
Answer:
B
Step-by-step explanation:
This is a reflection over the y-axis. The x value is changing sign while the y value is staying the same. The general rule for a reflection over the y axis is (x,y) --> (-x,y), and similarly for a reflection over the x axis is (x,y) --> (x,-y). When you reflect a point over an axis, you flip the sign of the opposite value.

1. A circle has a diameter from (8,2) to (0,2). Find the coordinates of the center of the circle and find the area. Use 3.14 as pi.
2. An amusement park just build a brand new Ferris wheel. But the Ferris wheel rolled 4 revolutions before coming to stop. The diameter of the Ferris wheel is 520 feet. What's the area of the circle? <----I'm not sure what was the question at the end I'm sorry but I think it was that.
Answer:
2. 212264
Step-by-step explanation:
Area of circle: 3.14(r^2)
we need to divide the 520 in half first
520/2 = 260
Now we do the equation!
3.14(260^2)
We get 212264 as our final answer :)

The smiley face has a radius of 8cm. What is the area of the smiley face?
16 sq. feet
50.24 sq. feet
128 sq. feet
200.96 sq. feet
Answer:
B.
Step-by-step explanation:
The smiley face has a radius of 8 centimeters.
We need to find the area of the smiley face.
The formula to find the area of a circle is:
A = [tex]\pi[/tex]r²
A = (3.14)(8)(2)
A = (25.12)(2)
A = 50.24
The area of the smiley face would be 50.24 square feet.

Their wages increase at intervals of $6 each hour.
6*1 = $6
6*2 = $12
6*3 = $18
6*4 = $24
6*5 = $30
6*6 = $36
6*7 = $42
6*8 = $48
This shows a proportional relationship between the wages earned and the number of hours worked.

Answer:
Q: Which statement is correct for the graph of the specified function?
A: The x-values of the linear function increase as the y-values decrease.
Q: Which statement is correct for the graph of the specified function?
A: The maximum value of the quadratic function occurs at y = 4.
Step-by-step explanation: The minimum value of the quadratic function occurs at x = 0 is false because this quadratic does not have a minimum value. It has a maximum value when y=4. The true statement is that the x-values of the linear function increase (go up) as the y-values decrease (go down). Also i took the test
Tyrone read a book for his school project. On the first day, he read 40 pages. On the second day, he read 1 4 of the remaining pages. After the second day, he still had to read 1 2 of the total number of pages to complete the book. How many pages are there in the book?
Answer:
160
Step-by-step explanation:
he read 40 pages on the first day. he read 1/4 of the remaining pages, and still had 1/2 of the book to read. this means that 40 is about 1/4 and to find the total amount of pages, you have to multiply 40 by 4.
40 x 4 = 160
hope this helps :)
Answer:
70 pages. (If by 1 4 and 1 2, you mean fractions.)
Step-by-step explanation:
1/4 of 40 is 10. This is calculated by dividing 40 by 4, since the denominator in 1/4 is 4.
1/2 of 40 is 20. This is calculated by dividing 40 by 2, since the denominator in 1/2 is 2.
Add that together and that's 70.
A counter recorded 254 revolutions of the bicycle wheel diameter 5/4 how far did bicycle travel use 22/7 for pi
Answer:
In 254 revolutions, the bicycle will travel [tex]997.85m[/tex].
Circumference :
The circumference of bicycle is given as,
[tex]C = \pi d[/tex]
Where [tex]d[/tex] is diameter of bicycle.
Given that, [tex]d = \frac{5}{4}, \pi = 22/7[/tex]

Now,to get rid of the denominator, Tiger multiplys both sides of the equation by the denominator.
Here's how:
x-1
——— • x = 0 • x
x
Now, on the left hand side, the x cancels out the denominator, while, on the right hand side, zero times anything is still zero.

Write an expression for the total number of seashells they collected. b. If the total number of seashells they collected is 45, determine the number of seashells each of them have.
Answer:
Ken, Leon, and Mark collect seashells as a hobby. Ken has (3x - 5) seashells, Leon has (2x +1) seashells, and Mark has (0.25x + 7) seashells. a. Write an expression for the total number of seashells they collected.
The answer:
Ken has 5 shells, Leon has 2 shells, Mark has 1.50 shells
how do we know:
because the 5 is negative we have -5 + -5=0 because negatives only go up by subtracting so 0+-5 is 5.
because the 1 is positive we can do 1+1 as were doing 2x1 so 1+1=2.
because we are doing 0.25x7 we need to know that we can flip the problem so we get 7x0.25. this makes things easy for you and me, we already know that 4 0.25's make 1 and we also know that 0.25+0.25 is 0.50 and 1 + 0.50 is 1.50 or just 1.5
