Using linear functions and the given table, it is found that:
The quantity demanded at $10.20 is of 170,000 of subscriptions.The quantity supplied at $10.20 is of 290,000 of subscriptions.The quantity supplied will be equal to 200,000 at a price of $9.87.What is a linear function?A linear function is modeled by:
y = mx + b
In which:
m is the slope, which is the rate of change, that is, by how much y changes when x changes by 1.b is the y-intercept, which is the value of y when x = 0, and can also be interpreted as the initial value of the function.From the table, we have that:
The quantity demanded at $10.20 is of 170,000 of subscriptions.The quantity supplied at $10.20 is of 290,000 of subscriptions.For the supply equation, we have two points:
(9.8, 190), (10, 220).
Hence the slope is given by:
m = (220 - 190)/(10 - 9.8) = 150.
Hence:
y = 150x + b.
When x = 9.8, y = 190, hence:
190 = 150(9.8) + b
b = -1280.
Hence:
y = 150x - 1280.
We want to find x when y = 200, hence:
200 = 150x - 1280
x = 1480/150
x = $9.87.
The quantity supplied will be equal to 200,000 at a price of $9.87.

Which two of the following are benefits of consumer program
They help prosecute company’s that sell unsafe products
They’re funded by taxpayers not consumers
They help maintain industry standards by issuing professional licenses
They help consumers identify the best product reviews from various sources
Among the four options provided, the benefits of consumer program are that they help prosecute companies that sell unsafe products to consumers and they also help consumers identify the best product reviews from various sources.
As per the question statement, we are required to determine the options from the given four, which are the best possible matches to being benefits of consumer program.
To solve this question, we will check for the possibility of every option by logical reasoning.
Option (A) is "They help prosecute company’s that sell unsafe products" which is true, and thus protects the consumer against frauds or exploits and health issues. Hence, this is definitely a benefit of consumer program.
Option (B) is "They’re funded by taxpayers not consumers" which is illogical because taxpayers are the consumers themselves. Hence, this is not a benefit of consumer program.
Option (C) is that "They help maintain industry standards by issuing professional licenses" which is false because forum has nothing to do with issuing licenses; It ensures that consumers are served with best quality products at the best prices and takes legal action against fraudulency. Hence, this is not a benefit of consumer program.
Finally, Option (D) is that "They help consumers identify the best product reviews from various sources" which is true. Hence, this is definitely another benefit of consumer program.
Consumer Program: This is a program by which key members of a client company, such as the marketing team, spend time directly with consumers or other people representing the client's existing or target customers. This may be done occasionally or on a regular basis, and at a central location or at customers' house.To learn more about Consumer Program, click on the link below.

solve each system of inequalities and indicate any three solutions. x-0.8 <0, -5x<10
The three solutions of the inequalities are x < 0 , x < 0.8 , x< -2
What are inequalities?Inequalities are defined as mathematical expressions in which both sides are not made equal to each other.
Given the inequalities;
x-0.8 <0-5x<10Let's solve for the value of x
x - 0.8 < 0
Make 'x' the subject
x < 0 + 0. 8
x < 0. 8
-5x < 10
Make 'x' the subject by dividing both sides by - 5
-5x/ 5 < 10/ -5
x < -2
Thus, the three solutions of the inequalities are x < 0 , x < 0.8 , x< -2

how to turn y=3x+45 into ax+by=c form
The given equation y = 3x + 45 in form ax+by=c is 3x - y = - 45.
What are linear equations?Ax+By=C is the usual form for two-variable linear equations. A standard form linear equation is, for instance, 2x+3y=5. When an equation is given in this format, finding both intercepts is fairly simple (x and y). When attempting to solve systems of two linear equations, this form is also very helpful. A linear equation has the slope-intercept form y = MX + b. Variables in the equation are x and y. When x is 0, the numbers m and b provide the line's slope (m) and the value of y(b). Because (0,y) is the location where the line crosses the y-axis, the value of y when x is 0 is referred to as the y-intercept.So, y=3x+45 into ax+by=c form:
y = 3x + 45 ⇒ Bring y to the other side of the equation and bring 45 to the opposite side of the equation as: y = 3x + 45 ⇒ 3x - y = - 45Therefore, the given equation in form ax+by=c is 3x - y = - 45.

x% of 6 plus y% of 6 can be expressed as x + y = 1.83.
A percentage is a quantity or ratio that is expressed as a fraction of 100. The symbol "%" is used to denote percentage. The percentage is denoted by the abbreviations "pct" or "pc". In other words, the percentage is measured in terms of 100 and is defined as the amount of one quantity that is made up of another.
A finite combination of symbols that are well-formed in accordance with context-dependent principles is referred to as an expression or mathematical expression.
The sum of x% of 6 and y% of 6 is 11%.
Therefore,
x% of 6 + y% of 6 = 11%
x% × 6 + y% × 6 = 11%
[tex]\frac{x}{100} \times 6 + \frac{y}{100} \times 6 = \frac{11}{100}[/tex]
Taking [tex]\frac{6}{100}[/tex] common.
[tex]\frac{6}{100}(x+y)=\frac{11}{100}[/tex]
6( x + y ) = 11
Dividing each side by 6.

Which statement is true about the function f(x) = 8x^3?
The function is even because f(–x) = f(x).
The function is odd because f(–x) = f(x).
The function is even because f(–x) = –f(x).
The function is odd because f(–x) = –f(x).
The function f(x) = 8x³ satisfies the condition f(-x) = -f(x) and is odd. D.
To determine whether the function f(x) = 8x³ is even or odd, we need to analyze the symmetry of the function with respect to the y-axis and the origin.
Even function:
If a function is even, it satisfies the condition f(-x) = f(x), meaning that the function is symmetric with respect to the y-axis.
Odd function:
If a function is odd, it satisfies the condition f(-x) = -f(x), meaning that the function is symmetric with respect to the origin.
Now, let's analyze the given function, f(x) = 8x³:
Testing for evenness:
If we substitute -x for x in the function, we have f(-x) = 8(-x)³
= -8x³.
This is not equal to f(x) = 8x³.
The function f(x) = 8x³ is not even.
Testing for oddness:
If we substitute -x for x in the function, we have f(-x) = 8(-x)³
= -8x³.
This is equal to -f(x) = -8x³.
The function is odd because f(–x) = –f(x).
