Answer:
1. Skyler's processes are incorrect. She put (3^6)^x = 9, but when working with exponential problems, both sides have to have the same base. 3 does not equal nine, so you can automatically rule out her approach.
2. Robert's processes are correct. He set both bases equal to each other and then solved for the exponents.
3. Kaitlyn is also correct, she set the bases equal to 3 and solved for the exponents.
Step-by-step explanation:
When working with exponents, the goal is to get the bases equal to each other. In this case, you could have set it equal to 9 (which Robert did) or you could have set it equal to 3 (like Kaitlyn did). But you never want the bases to be conflicting, which is what Skyler did. Just by looking at the problem and using deductive reasoning, it is likely that Robert and Kaitlyn are both correct, since they have the same answers, although they used different methods, but it is still important to look at the steps.
Skyler's one mistake was setting 3 = 9, because that is impossible. If you plug in her answer of 3/2 into x, you get a ridiculous number of 19,683 = 9, which is not possibly true. For the others, when you plug in 1/3, you get 729^(1/3) = 9, so 9=9.
Hopefully this makes sense, if not, I can try to explain it better. Thanks much & have a wonderful day.
The explanation of whether Skyler, Robert or Kaitlyn were correct/wrong and the reason from their processes is that;
1) Skyler is wrong because she didn't make the bases of both sides to be equal before equating the exponents.
2) Robert is correct because he made the bases of both sides to be the same before equating the exponents.
3) Kaitlyn is correct because she made the bases of both sides to be the same before equating the exponents.
1) SKYLER'S PROCESS;The problem skyler wants to solve is;
729^(x) = 9
The first step is to reduce 729 to the lowest base to get; [3^(6)]^(x) = 9
Next she did was to equate 6x to 9.
When working with equality of exponents both sides ought to have the same base and so she could have converted 9 to have same base of 3 as the left hand side after which she will equate the exponents.
So skyler is wrong.
2) ROBERT'S PROCESS;We saw that skyler didn'take both bases equal to each other but now Robert has done the correct thing by having;
9^(3x) = 9¹
After which he equated the exponents to get;
3x = 1
x = 1/3
Thus; Robert is correct
3) KAITLYN'S PROCESS;Kaitlyn is also correct because she followed the same correct pattern of ensuring the bases are the same before equating their exponents.

Explain why the expressions 1 2x + 1 2x and x are equivalent.
Answer:
Because x remains the same in the expressions
Step-by-step explanation:
Which function listed below has a greater rate of change
than the one in the graph?
A. f(X)= -0.3x + 2
B. f(X)= x + 1
C. f(X)= 0.1x + 2
D. f(X)= -0.25x - 3
A slope is also known as the gradient of a line. The listed function that has a greater rate of change than the one in the graph is f(X)= x + 1.
What is Slope?A slope also known as the gradient of a line is a number that helps to know both the direction and the steepness of the line.
slope = (y₂-y₁)/(x₂-x₁)
The coordinates through which the line of the graph is passing are (0,-4) and (6,0). Thus, the slope of the given line is,
Slope, m = (-4 - 0)/(0 - 6) = -4/-6 = 2/3 = 0.6667
Comparing the given equation with the general equation of a line, y=mx+c, where m is the slope of the line. Therefore, the slope of the given lines is,
A. f(X)= -0.3x + 2
slope = -0.3x
Hence, the slope is less than the slope of the given graph.
B. f(X)= x + 1
slope = 1
Hence, the slope is greater than the slope of the given graph.
C. f(X)= 0.1x + 2
slope = 0.1x
Hence, the slope is less than the slope of the given graph.
D. f(X)= -0.25x - 3
slope = -0.25x
Hence, the slope is less than the slope of the given graph.
Hence, the listed function that has a greater rate of change than the one in the graph is f(X)= x + 1.

The triangle for this question has been attached.
Answer:
LI = 18
Step-by-step explanation:
From ratio of corresponding sides of a triangle, we know that from the attached image, we can say that;
JK/KH = JL/LI
We are given;
JK = 7
KH = 21
JL = 6
Plugging in relevant values, we have;
7/21 = 6/LI
Making LI the subject, we have;
LI = 21 × 6/7
LI = 18
Dena, Barb, Ryan, and Joe played a game where the lowest value wins. Dena's score was 3. Barbs score was -6. Ryan's score was -4. And Joe's score was -2. A) Joe's score beat Dena's score B) Ryan's score beat Barbs score C) Joe had the worst score D) Dena won the game
Answer:
A.) Joe's score beat Dena's score
Step-by-step explanation:
When you use negative numbers (Numbers that start with a negative sign (-)), the bigger the number after the negative, the smaller the number and also a negative number is always less than a positive number. This means that Joe's score beats Dena's score, because Joe's score is negative and Dena's score is positive, so Joe's score is lesser than Dena's score.

Given the points (-4, 13) and (6,-2) find the slope in simplest form?
Sorry i miscalculated this one
Answer:
-3/2
Step-by-step explanation:
(see attached for reference)
the formula for slope is given as :
slope, m = (y₂-y₁) / (x₂-x₁)
in our case , we are given
(x₁,y₁) = (-4, 13)
(x₂, y₂) = (6, -2)
substitute these into the formula above:
m = (y₂-y₁) / (x₂-x₁)
= [-2 - 13] / [6 - (-4) ]
= -15 / 10
= -3/2
Hannah wants to rewrite 18+12 using the greatest common factor and the distributive property. Which expression should she write?
Answer:
6(3+2)
Step-by-step explanation:
Distributive property:
ab + ac = a(b+c)
where a = greatest common factor (GCF)
GCF of each factor
18 = 2×3×3
12 = 2×2×3
GCF of 18 and 12 = 2×3
= 6
Therefore,
18 + 12 = 6(3) + 6(2)
= 6(3+2)
Where,
6 = a
3 = b
2 = c
ab + ac = a(b+c)

Mrs. Blue has eight packages of pencils that she wants to distribute evenly between her sixth grades students. There are 24 pencils in each package, and she has 22 students. How many pencils will be left over after Mrs. Blue has given each student the same number of pencils?
Answer:
2
Step-by-step explanation:
If there are 22 students and she has 24 pencils she would need to give each of them 1 pencil. 24-22= 2
The number of pencils will be left over after Mrs Blue has given each student the same number of pencils is 16 pencils.
Given that, Mrs Blue has eight packages of pencils that she wants to distribute evenly among her sixth grades students. There are 24 pencils in each package, and she has 22 students.
We need to find out how many pencils will be left over after Mrs Blue has given each student the same number of pencils.
What is the unitary method?The unitary method is a process by which we find the value of a single unit from the value of multiple units and the value of multiple units from the value of a single unit. It is a method that we use for most of the calculations in math.
There are 24 pencils in each package and there are eight packages of pencils.
So, the total number of pencils=8×24=192
Now, she is distributing evenly among 22 students=192/22=8.72
Then, 8×22=176
Mrs Blue is distributing 8 pencils to each student.
Number of pencils left=192-176=16
Hence, the number of pencils will be left over after Mrs Blue has given each student the same number of pencils is 16 pencils.
