The answer is C, because there are two different numbers correlated to the same number on the Y side. The table does not represent a function.
The table is not a function because: A. one x-value corresponds to two different y-values.
How to Identify a Table that Represents a Function?If each x-value on a table of values is assigned to only one y-value, that table represents a function. If an x-value corresponds to more than one y-value, the table is not a function.
Thus, the x-value, 5, corresponds to two y-values, 2 and 5. Therefore the table does not represent a function.
The answer is: A.

The revenue, in dollars. of a company that produces video game systems can be modeled by the expression 52 +
2t - 80. The cost in dollars, of producing the video game systems can be modeled by 5.22 -+ 100, where x is the
number of video game systems sold. If profit is the difference between the revenue and the cost, what expression
represents the profit?
Profit can be modeled by the polynomial expression
If 1,000 video game systems are sold, the company's profit is $
Answers
Answer:
1). Profit = 3x - 180
2) Profit of selling 1000 video games = $2820
Step-by-step explanation:
Expression for the revenue = 5x² + 2x - 80
Expression for the production cost of the video games = 5x² - x + 100
Since, profit is the difference between the revenue and the cost,
Expression for the profit will be,
Profit = Revenue - Cost
= (5x² + 2x - 80) - (5x² - x + 100)
= 5x² + 2x - 80 - 5x² + x - 100
= 3x - 180
Here, x = Number of video games sold
If number of video games sold = 1000
Profit = (3×1000) - 180
= 3000 - 180
= $2820
What is the total area of the figure below?
Answers
To find the area of this figure you need to separate it into different sections.
First to find the area of the triangle on the left is multiple 8 by 3, giving the area of 24.
Second find the area of the rectangular shape towards the left, and ignore the triangle ends on both sides for now. To find the area of the rectangle multiply 10 by 9.
Lastly, to find the area of both triangles on both ends is to multiply 9 by 3. The three is found by subtracting 10 from 16 and dividing it by two.
Adding all the areas together gives you the answer = 141 in^2

A chemist has a bottle of a 1% acid solution and a bottle of a 5% acid solution. She wants to mix the two solutions to get 100 ml of a 4% acid solution. Follow the steps below to find how much of each solution she should use.
Part 2 out of 3
Use the information in the table to write a system of equations.
Answers
Answer:
12% alkaline
Step-by-step explanation:
The amount of 1% acid solution she needs to mix is 25 ml while the percentage of 5% acid solution she needs to mix is 75 ml.
Given to us
A chemist has a bottle of a 1% acid solution and a bottle of a 5% acid solution.
She wants to mix the two solutions to get 100 ml of a 4% acid solution.
Assumption
Let the amount of 1% acid solution be x ml, and the amount of 5% acid solution be y ml.
Total Amount of the Final SolutionAs the chemist wants to mix the two solutions to make 100 ml of solutions, therefore,
amount of 1% acid solution + amount of 5% acid solution = 100ml
x + y = 100.....equation 1
Solving for y,
y = 100 - x
What is the % of the acid in the mixture?We know that the mixture is having a 4% concentration and is 100 ml in volume.
[tex](1\%)x+(5\%)y = (4\%)100\\0.01x+0.05y=0.04\times 100\\[/tex]
Substitute the value of y,
[tex]0.01x+0.05(100-x)=0.04\times 100\\\\0.01x + (0.05\times 100)-(0.05\times x) = 4\\\\0.01x + 5 -0.05x =4\\\\0.01x-0.05x = 4-5\\\\0.04x = 1\\\\x=\dfrac{1}{0.04}\\\\x = 25\ ml[/tex]
Substitute the value of x in equation y,
[tex]x+y = 100\\25 +y =100\\y = 100-25\\y=75\ ml[/tex]
Hence, the amount of 1% acid solution she needs to mix is 25 ml while the percentage of 5% acid solution she needs to mix is 75 ml.

log, 243
log, 243
Answers
Answer:
[tex]x = \frac{log\ 243}{log\ 3}[/tex]
Step-by-step explanation:
Given
[tex]3^x = 243[/tex]
Required
Express as a logarithm
[tex]3^x = 243[/tex]
Take log of both sides
[tex]log\ 3^x = log\ 243[/tex]
Apply the following law of logarithm
[tex]log\ a^b = b\ log\ a[/tex]
So, the expression becomes:
[tex]log\ 3^x = log\ 243[/tex]
[tex]x\ log\ 3 = log\ 243[/tex]
Divide both sides by log 3
[tex]\frac{x\ log\ 3}{log\ 3} = \frac{log\ 243}{log\ 3}[/tex]
[tex]x = \frac{log\ 243}{log\ 3}[/tex]
Hence, the expression in base 10 is:
[tex]x = \frac{log\ 243}{log\ 3}[/tex] or [tex]x = \frac{log_{10}\ 243}{log_{10}\ 3}[/tex]

what is the equation, in point-slope form, that is perpendicular to the given line and passes through the point (-4,-3)?
Answers
Answer:
C. y + 3 = ¼(x + 4)
Step-by-step explanation:
✔️First, find the slope of the given line on the graph that it is perpendicular to:
Slope (m) = ∆y/∆x = -4/1 = -4
Thus, the slope of the line that is perpendicular to the given line would be the negative reciprocal of -4.
The negative reciprocal of -4 = ¼
✔️Find the equation in point-slope form, y - b = m(x - a) using slope and a point on the line:
Substitute m = ¼, (a, b) = (-4, -3) into y - b = m(x - a):
y - (-3) = ¼(x - (-4))
y + 3 = ¼(x + 4)
