Answer:
Step-by-step explanation:
First we need to find inverse function of f(x) which is written in a form of (f(x))^(-1)
That means that we are actually looking for function f(y) and we need to solve this equation for "y"
y=(4x + 1)/3
3y = 4x + 1
4x = 3y - 1
x = (3y - 1) / 4
f(y) = (3y - 1)/4
Now we simply put the value of 3 instead of y and find the answer:
f(y=3) = (3*3-1)/4 = 2

Question 2
At how many values of a(0° < a < 360°) does pentagon A'B'C'DE' coincide with pentagon ABCDE? What is significant about this
number?
Answer: each time the pentagon is rotated 72, it maps back onto itself. There are five values of a for which the pentagon maps back onto itself. this is the same as the number of sides of the pentagon.
Step-by-step explanation: edmentum
A regular pentagon has 5 congruent sides and a measure of 360 degrees, at its center.
Pentagon ABCDE and A'B'C'D'E coincide at 4 values of (a)
The angle where pentagon ABCDE and pentagon A'B'C'D'E coincide is:
[tex]\mathbf{\theta = \frac{360}{5}}[/tex]
[tex]\mathbf{\theta = 72}[/tex]
Other angles between 0 and 360 degrees, where pentagon ABCDE and pentagon A'B'C'D'E coincide are multiples of 72.
So, we have:
[tex]\mathbf{a = 72^o,\ 144^o,\ 216^o,\ 288^o}[/tex]
The count of angles is 4
Hence, pentagon ABCDE and A'B'C'D'E coincide at 4 values of (a)

a basketball team won 10 games and lost 15. what is the ratio of wins to the total number of games
Answer:
The total number of games =25 which is 10+15
then the number of wins are 10.
which is 10/25.
A ratio shows us the number of times a number contains another number. The ratio of wins to the total number of games is 2/5.
What is a Ratio?A ratio expresses the number of times one number contains another. For example, if a dish of fruit contains eight oranges and six lemons, the orange-to-lemon ratio is eight to six. Similarly, the lemon to orange ratio is 6:8, while the orange to total fruit ratio is 8:14.
Given that a basketball team won 10 games and lost 15. Therefore, the total number of games that the team plays is,
Total number of games = games won + games lost
= 10 + 15
= 25
Now, the ratio of wins to the total number of games can be written as,
Ratio = Games Won/ Total number of games
= 10/25
= 2/5
Hence, the ratio of wins to the total number of games is 2/5.

A Jar contains 4 white chips, 5 purple chips, and 1 black chip. Chips are selected randomly one at a time, and are not
replaced
P(white, then purple, then black)
Answer:
1 / 36
Step-by-step explanation:
There are 4 + 5 + 1 = 10 chips so there are 10 * 9 * 8 = 720 ways to choose 3 chips and not replace them. There are 4 ways to choose the white chip, 5 ways to choose the purple chip and 1 way to choose the black chip so there are 4 * 5 * 1 = 20 successful ways, therefore, the probability is 20 / 720 = 1 / 36.

Step-by-step explanation:
Answer:
8 weeks
Step-by-step explanation:
he receives 5 for a week and has 15 in his bank account, so that means we have to subtract 15 from 55 to find how many he has.
55-15=40
1 week= 5

The function g(x) = 3x3 + x is an odd function. Which transformations of g(x) would result in odd functions? Check all that apply. –g(x) g(2x) g(x − 1) g(x) − 3 g(–x)
Answer:
-g(x), g(2x), g(-x)
Step-by-st-ep explanation:
if f (–x) = f (x), so all of the signs are the same
you can also try on desmos, the graph is more helpful than words explain sometimes
The functions that are odd are -g(x), g(2x), and g(-x). The correct option is A, B, and E.
What is a Function?A function assigns the value of each element of one set to the other specific element of another set.
For an odd function, -f(x) = f(-x).
Given that the function, g(x) = 3x³ + x is an odd function. Therefore, the transformation of the function that will again result in an odd function is,
A.) –g(x)
-g(x) = -(3x³ + x) = -3x³ - x
g(-x) = 3(-x)³ + (-1x = -3x³ - x
Thus, this is an odd function.
B.) g(2x) ⇒ Since this will result in the same function, the only difference will be that the function will be vertically stretched.
E.) g(–x)
-g(x) = -(3x³ + x) = -3x³ - x
g(-x) = 3(-x)³ + (-1x = -3x³ - x
Thus, this is an odd function.
Hence, the functions that are odd are -g(x), g(2x), and g(-x).

Step-by-step explanation:
Given: If X, then Y. If Y, then Z. Y is true. So: X is unknown, Z is unknown X is unknown, Z is true X is false, Z is true X is true, Z is true
The correct option that gives a proper logic for the argument that "If X, then Y. If Y, then Z. Y is true" is given by;
Option B; X is unknown, Z is true
This question is based on the principles of logic. Logic helps us distinguish between valid and invalid arguments.Now, the argument here is that;If X, then Y. If Y, then Z. Y is true.
Now, from this argument, we can see that Y depends on X and then Z depends on Y.Now, we are told that Y is true. Since Z depends on Y as seen that If Y, then Z, we can say that Z is also true.However, we can't say anything about X as X is unknown.

Is it perpendicular, neither, of parallel. Show work
Perpendicular.
x = -1 is a vertical line intersecting the x-axis at (-1, 0).
y = -1 is a horizontal line intersecting the y-axis at (0, -1).
Because these lines are both straight, they will eventually intersect at (-1, -1). They will also form 90° angles, the definition of perpendicular.

Step-by-step explanation:
22. The compound inequality [tex]1-4x < 21[/tex] and [tex]5x+2 > 22[/tex] is intersection, option A is correct.
21. [tex]x+y=3^2[/tex] is not a function. Option A is correct.
22. The compound inequality [tex]1-4x < 21[/tex] and [tex]5x+2 > 22[/tex] is an example of a compound inequality involving "and."
Both inequalities need to be satisfied simultaneously for the compound inequality to be true.
Hence, the compound inequality is intersection.
21. A function is a relationship between two variables in which each input value (x) corresponds to exactly one output value (y).
In this case, the equation [tex]x+y=3^2[/tex] does not represent a clear relationship between x and y.
[tex]x+y=3^2[/tex] represents a curve in the xy-plane rather than a function.
Hence, [tex]x+y=3^2[/tex] is not a function.

Each person at a picnic chose atleast one piece of a fruit one third of the people chose an apple three -quaters of the people chose a orange what fraction of the people chose both of them
Answer:
-1/12x
Step-by-step explanation:
Let total people at the picnic=x
People who chose apple= 1/3x
People who chose orange= 3/4x
People who chose each of the fruit= People who chose apple + People who chose orange
=1/3x + 3/4x
= 4x+9x / 12
=13/12x
People who chose each of the fruit= 13/12x
what fraction of the people chose both of them?
Fraction of the people who chose both fruits= Total people at the picnic - People who chose each of the fruit
=x - 13/12x
=12x- 13x /12
= -1/12 x
