The graph of the inequality is drawn by placing a shaded circle at 4 as the starting point of ray pointing towards negative infinity
The students that created inequalities with appropriate solution set are;
A. Amanda
D. Diana
Reasons:
Question: The table of the question is presented as follows, and the graph of the inequality is attached
[tex]\begin{array}{|l|l|}\mathbf{\underlie{Amanda}}&-3\cdot x + 5 > -7\\&\\\mathbf{\undrline{Briana}}& \dfrac{1}{2} \cdot (2\cdot x - 4) >2 \\&\\\mathbf{\undrline{Courtney}}&-7\cdot x + 8 > -3 \cdot x +24\\&\\\mathbf{\undrline{Diana}}&9\cdot x - 6 <3 \cdot x+18\end{array}\right][/tex]
Solution:
The inequality with the same solution as the given graph is x < 4
The inequalities created by the students are;
Amanda;
-3·x + 5 > -7
Rearranging the above inequality gives;
-3·x + 5 - 5 > -7 - 5
-3·x > -12
Dividing both sides by (-1) and reversing the inequality sign gives;
[tex]\dfrac{-3 \cdot x}{-3} = x < \dfrac{-12}{-3} = 4[/tex]
x < 4
Therefore;
The solution of the inequality created by Amanda is x < 4, which is the same as the solution set of the graph, and therefore, is appropriateBriana;
The solution set created by Briana is [tex]\dfrac{1}{2} \cdot (2\cdot x - 4) >2[/tex]
Multiplying both expressions on either side of the equality by 2 gives;
[tex]2\times \dfrac{1}{2} \cdot (2\cdot x - 4) >2\times 2[/tex]
(2·x - 4) > 4
2·x > 4 + 4 = 8
[tex]x > \dfrac{8}{2}[/tex]
Therefore
x > 4
The solution of the inequality created by Briana is x > 4 which is not appropriate for the given graphCourtney;
The inequality created by Courtney is -7·x + 8 > -3·x + 24
Rearranging gives;
8 - 24 > -3·x + 7·x
-16 > 4·x
4·x < -16
[tex]x < \dfrac{-16}{4}[/tex]
x < -4
Courtney's solution is x < -4, which is not an appropriate solution to the given graphDiana;
Diana's solution is 9·x - 6 < 3·x + 18
Rearranging, we get;
9·x - 3·x < 18 + 6
6·x < 24
[tex]x < \dfrac{24}{6}[/tex]
x < 4
Therefor;
Diana's solution is an appropriate solution to the given graphTherefore, the students that created inequalities with appropriate solution set are;
A. Amanda

Write an equation to model the relationship between the number of weeks, x, and the number of views, f(x).
Enter the correct answer in the box by replacing the values of a and b.
Answer:
a = 5120
b = 1.25
Step-by-step explanation:
Let the exponential function representing the given table is,
f(x) = [tex]a(b)^x[/tex]
Here, f(x) = Number of views
x = Number of weeks
We choose two points from the given table and satisfy the equation of the function.
Let the points are (0, 5120) and (1, 6400)
For a point (0, 5120),
f(0) = a(b)⁰ = 5120
a = 5120
Now for the second point (1, 6400),
6400 = 5120(b)¹
b = [tex]\frac{6400}{5120}[/tex]
b = 1.25
Therefore, a = 5120 and b = 1.25 are the values.
Answer:
f(x)=8(0.5)^x

7. Jasmine buys a pack of 15 socks for $9.00. Shawn buys a pack of 20 socks for
$11.00. Write a ratio to represent they paid to the number of socks. Who got a better
deal on socks? Explain.
Answer: Well if you buy a pack of socks with 15 for $9 you are not getting the best deal over buying a pack of socks with 20 for $11. The reason behind this is because each sock is worth $0.6 meaning that you are only paying two extra dollars for five socks which would have normally cost $3. Shawn (with the 20 pack) is saving $1.

A triangle prism has a volume of 240m3.The area of the base is 16m2 what's is the height of the triangle prism
Answer:
The height is 45 m
Step-by-step explanation:
The volume of a triangular prism is V = (1/3)(area of base)(height)
If the voume is 240 m^3 and the area of the base 16 m^2, then the height of the prism is determined as follows:
3V = (area of base)(height)
Dividing both sides by (area of the base), we get:
3(240m^3)
height = ------------------------- = 45 m
16 m^2

Answer:
Length of the segment of a secant 'x' is 4 cm.
Step-by-step explanation:
If a secant and a tangent are drawn from a point outside the circle, then the product of the segments of the secant is equal to the square of the length of the tangent.
By this property,
[tex]4\times x = 8^2[/tex]
[tex]4x = 64[/tex]
[tex]x=\sqrt{16}[/tex]
[tex]x=4[/tex] cm
Therefore, length of the segment of a secant 'x' is 4 cm.

Answer: I think 8?
Step-by-step explanation:
You might be adding the 6 so therefore maybe you do 6+2= 8 if the median was eqaul to 6.
If this isnt right, I'm sorry!
Answer: 1
The set is:
6 1 5 4 8 7 2 1 2 2
First: We get the median of the original set. To do this we change it from highest to lowest.
1 1 2 2 2 4 5 6 7 8
Then we take the middle number of this set which is the median
2 and 4 are the middle so the median is 3
The median of set 1 is 3
Second: We get the median of the set but with another 6 added
1 1 2 2 2 4 5 6 6 7 8
Take the middle number of this set which is the median
4
The median of set 2 is 4
From this we know the median increases by 1 if the number 6 is added!

Bottom side: 7c - 1
Tall side: 6c + 2
P = 7c - 1 + 6c + 2 + 3c - 2 + 2c + 4c + 1 + 4c + 2
P = 26c + 2
2)
P = 26c + 2
P = 26(5) + 2
P = 132
3)
P = 2(l + w)
P = 2(3d - 2 + 5d + 1)
P = 16d - 2
4)
P = 16d - 2
P = 16(3) - 2

The total value of an investment was $305.33 after $240 was invested for 10 years compounded monthly. Find the interest interest rate.
Answer:
Interest rate = 2.41%
Step-by-step explanation:
The total value of an investment was $305.33 after $240 was invested for 10 years compounded monthly. Find the interest rate.
The formula to calculate the Interest rate for a Compound Interest is given as:
Solving for rate r as a decimal
r = n[(A/P)^1/nt - 1]
r = 12 × [(305.33/240.00)^1/(12)(10) - 1]
r = 0.0240996
Then convert r to R as a percentage
R = r * 100
R = 0.0240996 * 100
R = 2.41%/year
Therefore, the Interest rate = 2.41%
