(2x + 3y = 6)2
4x + 6y = 12
-4x + 3y = 12
Now add both
9y = 24, y = 24/9 = 8/3
2x + 3(8/3) = 6
2x + 8 = 6
2x = -2, x = -1
Finale answer: x = -1, y = 2 2/3

Which functions are symmetric about the y-axis? Check all of the boxes that apply.
Answers
The functions that are symmetric about the y-axis are;
1) The function in the first option; f(θ) = cos(θ)
2) The function in the third option; f(x) = x²
Reason for the above selection;
Definition;
A function is symmetric about the y-axis is also known to be an even function such that the same value of the function is arrived at when x is replaced with -x
Analysis of the graphs;
First Function Graph; The graph represents the graph of cos (θ)
∴ The function is f(θ) = cos(θ)
The value of the function when x = π, f(π) = -1
Similarly, the value of the when x = -π, f(-π) = -1
f(π) = f(-π)
∴ f(x) = f(-x)
Therefore; the first function is an even function
Second Function Graph; The function of the graph is x = y²
∴ y = √(x)
The value of the function when x = 4, y = f(4) = 2
However, the when x = -4, f(-4) does not exist
f(4) ≠ f(-4)
∴ f(x) ≠ f(-x)
Therefore; the second function is not an even function (the function, x = y², is however symmetric about the x-axis)
Third Function Graph; The function the graph represents is y = x²
The value of the function when x = 2, f(2) = 4
Similarly, the value of the when x = -2, f(-2) = 4
f(2) = f(-2)
∴ f(x) = f(-x)
Therefore; the third function is an even function
From the above, the functions which are symmetric about the y-axis, (even functions) are;
The first and the third functions

Productivity: My candy bar company made 100 million bars last year, sold for $1 each. I also paid [L] people last year, with an average salary of $100K last year. I have overhead cost of $10M. What was my TOTAL productivity (no units, rounded to 2 decimal places)?
Solution:
Total productivity is the average of labour and capital productivity weighted and adjusted to price fluctuations. It is the ratio of total output to the total input. The total productivity is given by the formula:
Total productivity = total output / total input
Total output = Revenue = number of bars sold * price per bar
Total output = 100 million * $1 = $100 million
Total input = Total salary + overhead cost
Total salary = number of people * average salary = 100 *$100000 = $10 million
overhead cost = $10 million
Total input = $10 million + $10 million = $20 million
Total productivity = total output / total input = $100 million / $20 million
Total productivity = 5

Calculating average speed:
1. A person walks 6.0 meters in a time of 2.0 seconds. What is the average speed. PLEASE HELP!!!
Answers
Answer:
3 meters per second.
Step-by-step explanation:
The formula for finding speed is: [tex]s = \frac{d}{t}[/tex]. D is distance. T is time. So in your case, you would divide 6.0 (distance) by 2.0 (time). Your answer is 3. Add meters per second because you divided meters/seconds.
Hope it helps!
Speed= distance divided by time
6.0 divided by 2.0 = 3

Graph the line that passes through the points (9,-8) and (9,6) and determine the
equation of the line.
Answers
Answer:
x = 9
Step-by-step explanation:
The standard form of equation of a line is expressed as y = mx+c
m is the slope
c is the y intercept
Note that the line does not have a slope and the x intercept of the line is a point where the line cuts the x axis. Hence the equation of the line will be expressed as x = c where c is the x intercept;
From the graph, the x intercept =9. Hence the equation of the given line is x = 9

Answers
Answer:
2.03 cupcakes per minute.
Step-by-step explanation:
The baker can decorate (61/30) cupcakes per minute, hence she can decorate 2.03 cupcakes per minute.
Hope this helped!
Answer:
The baker can decorate 2 cupcakes per minute
Step-by-step explanation:
The baker can decorate 2 cupcakes per minute and to find this you would divide 61 by 30 and you'd get 2.03333 repeating but you can't decorate three hundredths of a cupcake so you would round it to the nearest whole number to get 2 cupcakes per minute
