This means x = 2, y = 3 and z = 1
========================================================
Work Shown:
Double everything in the second equation to get 4x-2y+4z=6
Add this result to the first equation
[tex]x+2y-4z = 4\\4x-2y+4z = 6\\5x+0y+0z = 10[/tex]
The first two lines of that expression above shows us adding x+2y-4z=4 to the equation 4x-2y+4z = 6
The x terms add to x+4x = 5x
The y terms add to 2y+(-2y) = 0y
The z terms add to -4z+4z = 0z
The terms on the right hand side add to 4+6 = 10
That's how we end up with the new equation 5x+0y+0z = 10
That becomes 5x = 10 which solves to x = 2 when we divide both sides by 5.
------------------------
Use this x value in the third original equation to find z
3x-8z = -2
3(2)-8z = -2
6-8z = -2
-8z = -2-6
-8z = -8
z = -8/(-8)
z = 1
------------------------
Use the x and z values we found to find y
x+2y-4z = 4
2+2y-4(1) = 4
2+2y-4 = 4
2y-2 = 4
2y = 4+2
2y = 6
y = 6/2
y = 3
----------------------
Overall we get the solutions to be x = 2, y = 3 and z = 1
We can say the solution as an ordered triple is (x,y,z) = (2,3,1)

Step-by-step explanation:
The easiest thing is to convert it to an improper fraction.
-2 1/9 turns into -19/9. -4 1/9 turns into -37/9.
-19/9 - (-37/9) here you would add because you are subtracting a negative number.
-19/9 + 37/9 change it to positive and then add.
-19+37=18
it was 18/9. that simplified is 2.

The activity rate for the Order Size activity cost pool under activity-based costing is closest to A. $59.78 per MH.
What is the activity rate under activity-based costing?The activity rate under activity-based costing is also called the cost driver rate.
The activity rate per cool pool can be computed by dividing the cost pool total cost by the cost driver total requirements.
Data and Calculations:Order size Overhead Costs = $579,866
Machine Hours (MHs) = 9,700
Activity rate for the Order Size = $59.78 ($579,866/9,700)

For the following graph, it is found that:
It represents a function, as it value of x is mapped to only one value of y.The inverse is a function, as the graph is one-to-one, that is, each value of y is mapped to only one value of x.When does a graph represents a function?A graph represents a function if it has no vertically aligned points, that is, each value of x is mapped to only one value of y.
For the graph in this problem, the statement is true, hence the graph is a function.
Is the inverse a function?The inverse of a graph will be a function if the original function is one-to-one, that is, each value of y is mapped to only one value of x, meaning that the graph has no horizontally aligned points.
This is also true for this function, hence the inverse is a function.

b) Which of these three measures of central tendency do you think is the least representative of the set of scores?
Answers
Answer:
Mean = 75

Given the data :
45 45 50 50 55 60 70 75 75 80 80 85 85 85 85 90 95 95 95 100

The mean score :
ΣX / n ; n = sample size = 20
ΣX = 1500
Mean = 1500 / 20 = 75
Mode = most frequently occurring = 85 ( frequency of 4)
Median = 0.5(n + 1)th term
Median = 0.5(20 + 1)th term
Median = 0.5(21) th term
Median = 10.5th term = (10 + 11)th term / 2

Suppose f(x)=x^2+9x+8
1. Suppose F(x) is obtained by reflecting the graph over the y-axis. Find a formula for F(x).
Suppose g(x)=x^19-8x^6-x^5+7x^2+x+9.
1. Reflected over x-axis vertically
2. Reflected over y-axis horizontally
Answers
Using translation concepts, the functions are given as follows:
1. F(x) = x² - 9x + 8.
2. [tex]G(x) = x^{19} + 8x^6 - x^5 - 7x^2 + x - 9[/tex]
What is a translation?A translation is represented by a change in the function graph, according to operations such as multiplication or sum/subtraction either in it’s definition or in it’s domain. Examples are shift left/right or bottom/up, vertical or horizontal stretching or compression, and reflections over the x-axis or the y-axis.
In item 1, the function is:
f(x) = x² + 9x + 8.
When the function is reflected over the y-axis, we have that:
F(x) = f(-x),
Hence:
F(x) = (-x)² + 9(-x) + 8.
F(x) = x² - 9x + 8.
For item 2, the function is:
[tex]g(x) = x^{19} - 8x^6 - x^5 + 7x^2 + x + 9[/tex]
When the function is reflected over the x-axis, we have that:
G(x) = -g(x).
Hence:
[tex]G(x) = -x^{19} + 8x^6 + x^5 - 7x^2 - x - 9[/tex]
When the function is reflected over the y-axis, we have that:
Hence:
G(x) = G(-x).
[tex]G(x) = -(-x)^{19} + 8(-x)^6 + (-x)^5 - 7(-x)^2 - (-x) - 9[/tex]
[tex]G(x) = x^{19} + 8x^6 - x^5 - 7x^2 + x - 9[/tex]

Write a linear equation for the graph in point-slope form. Show your work. (2 points)
Use your equation to determine how long Grace was at birth. Show your work and explain how you can check your result using your knowledge of rate of change. (3 points)
Based on the data, how long do you predict baby Grace will be at 36 months of age? Use the rate of change to justify your answer. Does your answer make sense? Explain. (2 points)
Answers
The point-slope intercept equation is y - 20 = 3/4(x - 4).
The rate of change is 3/4.
At 0 months (at birth), Grace was 17 inches long.
At 36 months, Grace would be 44 inches long.
How to Create a Linear Equation?A linear equation of a graph can be represented in point-slope form as y - b = m(x - a), where (a, b) is a point on the graph and m is the slope.
Find the Slope (m) using two points (4, 20) and (8, 23):
Slope (m) = change in y/change in x = (23 - 20)/(8 - 4)
Slope (m) = 3/4
Substitute (a, b) = (4, 20) and m = 3/4 into y - b = m(x - a):
y - 20 = 3/4(x - 4) [point-slope intercept equation]
At birth, months would be x = 0. To find how long Grace was at birth, substitute x = 0 into y - 20 = 3/4(x - 4) to find the value of y:
y - 20 = 3/4(0 - 4)
y - 20 = 3/4(-4)
y - 20 = -3
y - 20 + 20 = -3 + 20
y = 17
This means that, at 0 months (at birth), Grace was 17 inches long.
At 36 months, substitute x = 36 into y - 20 = 3/4(x - 4) to find the how long Grace was (y):
y - 20 = 3/4(36 - 4)
y - 20 = 3/4(32)
y - 20 = 24
y - 20 + 20 = 24 + 20
y = 44
At 36 months, Grace would be 44 inches long.

Georgie spends $160 on clothes. She pays 6.5% in tax. How much does she spend altogether?
Answers
The correct answer is $170.4
Explanation:
The total Georgie spent is equal to the money spent on clothes ($160) added to taxes (6.5% of the price of the clothes). Now, to calculate the money spend on taxes follow this process:
1. Divide the total of money spent on clothes into 100 (this number represents 100%)
160 ÷ 100 = 1.6
2. Multiply this number by the specific percentage (6.5)
1.6 x 6.5 = $10.4 (This is the money spent on taxes)
Finally, add the value of taxes and the price of the clothes:
$160 + $10.4 = $170.4

The bakers at Healthy Bakery can make 170 bagels in 2 hours. How many
bagels can they bake in 14 hours? What was that rate per hour?
Answers
Given:
The bakers at Healthy Bakery can make 170 bagels in 2 hours.
To find:
How many bagels can they bake in 14 hours and the rate per hour.
Solution:
We have,
Number of bagels the bakers can bake in 2 hours = 170 bagels
Number of bagels the bakers can bake in 1 hours = [tex]\dfrac{170}{2}[/tex] bagels
= 85 bagels
Therefore, the average rate is 85 bagels per hour.
Number of bagels the bakers can bake in 14 hours = [tex]14\times 85[/tex] bagels
= 1190 bagels
Therefore, the bakers can bake 1190 bagels in 14 hours.
