Write an inequality to describe each situation. a. The minimum age for voting in the United States is 18 years old. Let a represent a voter's age. b. A theater seats up to 275 people. Let p represent the number of people attending a performance in the theater.
According to this inequality, the number of persons attending a theatrical inequality play, denoted by p, must be less than or equal to 275 in order for everyone to have a seat.
What is inequality?In mathematics, an inequality is a non-equal connection between two expressions or values. As a result, imbalance leads to inequity. In mathematics, an inequality connects two values that are not equal. Inequality is not the same as equality. When two values are not equal, the not equal symbol is typically used (). Various disparities, no matter how little or huge, are utilised to contrast values. We resuming our current status quo. Yet a variety of things lead to inequality: Negative values on both sides are split or added.
a. The disparity in representing the voting age in the United States is as follows:
a ≥ 18
In order to be eligible to vote, a voter's age, denoted by a, must be more than or equal to 18 years old.
b. The inequality used to depict a theater's seating capacity is:
p ≤ 275
According to this inequality, the number of persons attending a theatrical play, denoted by p, must be less than or equal to 275 in order for everyone to have a seat.

} One number is 8 times another. When the lesser number is subtracted from the greater, the result is 2 more than 5 times the lesser number. What are the numbers?
The numbers are 1 and 8.
We have,
Let's assume the lesser number as "x" and the greater number as "8x".
According to the given information, when the lesser number is subtracted from the greater, the result is 2 more than 5 times the lesser number:
8x - x = 5x + 2
Simplifying the expression:
7x = 5x + 2
Subtracting 5x from both sides:
2x = 2
Dividing both sides by 2:
x = 1
So, the lesser number is 1 and the greater number is 8 times that, which is 8.

Required
Complete the table
In probability, all probabilities add up to 1.
i.e.
\(P(Blue) + P(Red) + P(Yellow) = 1\)
Substitute 0.2 for P(Blue)
\(0.2 + P(Red) + P(Yellow) = 1\)
\(P(Red) + P(Yellow) = 1 - 0.2\)
\(P(Red) + P(Yellow) = 0.8\)
From the question, we understand that the frequency of yellow and red balls are the same.
Hence:
\(P(Red) = P(Yellow)\)
\(P(Red) + P(Yellow) = 0.8\) becomes
\(P(Red) + P(Red) = 0.8\)
\(2P(Red) = 0.8\)
Make P(Red) the subject
\(P(Red) = 0.4\)
Recall that:
\(P(Red) = P(Yellow)\)
Hence,
\(P(Yellow) = 0.4\)
So, the complete table is:

what is the domain and range
For the graphed function, we have:
Domain: (-1, 1) U (3, 5)
Range: (5, 2)
What is the domain and range of the graphed function?For any function y = h(x) we define the domain as the set of the inputs while we define the range as the set of the outputs.
To find the domain we need to look at the horizontal axis, we can see that the function is graphed on the intervals (-1, 1) and (3, 5), so the domain is:
D: (-1, 1) U (3, 5)
For the range we need to look at the vertical axis, the two intervals are (-4, 2) and (-5, 0), the union of these intervals gives:
(-4, 2) U (-5, 0) = (5, 2)
Then the range is R: (5, 2)

So, we have:
\(A = (-4,-1)\) ==> \((-4+4,-1) =(0,-1)\)
\(B = (-3,-5)\) ==> \((-3+4,-5) =(1,-5)\)
\(C =(-1,-1)\) ==> \((-1+4,-1) =(3,-1)\)

The rule is:
\((x,y) \to (x,y+3)\)
So, we have:
\((0,-1)\) ==> \(A' =(0,-1+3) = (0,2)\)
\((1,-5)\) ==> \(B' =(1,-5+3) = (1,-2)\)
\((3,-1)\) ==> \(C' =(3,-1+3) = (3,2)\)
The coordinates of A' B' and C' are:

A local museum charges $25 per adult and $12 per child for admission fees. At the end of a day, the museum made $9,014 in total admission revenue, not including sales tax, and had a total of 450 guests.
The system of equations below can be used to model the number of guests that were children, x, and the number of guests that were adults, y.
First, place a point on the graph representing the solution to the system of equations. Notice that one of the equations in the system has already been graphed.
Then, determine the approximate number of guests that were children and the approximate number of guests that were adults for that day.
The approximate number of guests that were children are 172 and adults are 278
How to determine the approximate number of guests that were children and adults for that day?From the complete question, we have the following system of equations
25x + 12y = 9014
x + y = 450
Make y the subject in x + y = 450
y = 450 -x
Substitute y = 450 - x in 25x + 12y = 9014
25x + 12(450 - x) = 9014
Expand the expression
25x + 5400 - 12x = 9014
Evaluate the like terms
13x = 3614
Divide both sides by 12
x = 278
Substitute x = 278 in y = 450 -x
y = 450 - 278
Evaluate
y = 172
Hence, the approximate number of guests that were children are 172 and adults are 278

Graph for f(x)=6^6 and f(x)=14^x
Graph Transformations
There are many times when you’ll know very well what the graph of a
particular function looks like, and you’ll want to know what the graph of a
very similar function looks like. In this chapter, we’ll discuss some ways to
draw graphs in these circumstances.
Transformations “after” the original function
Suppose you know what the graph of a function f(x) looks like. Suppose
d 2 R is some number that is greater than 0, and you are asked to graph the
function f(x) + d. The graph of the new function is easy to describe: just
take every point in the graph of f(x), and move it up a distance of d. That
is, if (a, b) is a point in the graph of f(x), then (a, b + d) is a point in the
graph of f(x) + d.
As an explanation for what’s written above: If (a, b) is a point in the graph
of f(x), then that means f(a) = b. Hence, f(a) + d = b + d, which is to say
that (a, b + d) is a point in the graph of f(x) + d.
The chart on the next page describes how to use the graph of f(x) to create
the graph of some similar functions. Throughout the chart, d > 0, c > 1, and
(a, b) is a point in the graph of f(x).
Notice that all of the “new functions” in the chart di↵er from f(x) by some
algebraic manipulation that happens after f plays its part as a function. For
example, first you put x into the function, then f(x) is what comes out. The
function has done its job. Only after f has done its job do you add d to get
the new function f(x) + d. 67Because all of the algebraic transformations occur after the function does
its job, all of the changes to points in the second column of the chart occur
in the second coordinate. Thus, all the changes in the graphs occur in the
vertical measurements of the graph.
New How points in graph of f(x) visual e↵ect

f(x) + d (a, b) 7! (a, b + d) shift up by d
f(x) Transformations before and after the original function
As long as there is only one type of operation involved “inside the function”
– either multiplication or addition – and only one type of operation involved
“outside of the function” – either multiplication or addition – you can apply
the rules from the two charts on page 68 and 70 to transform the graph of a
function.
Examples.
• Let’s look at the function • The graph of 2g(3x) is obtained from the graph of g(x) by shrinking
the horizontal coordinate by 1
3, and stretching the vertical coordinate by 2.
(You’d get the same answer here if you reversed the order of the transfor-
mations and stretched vertically by 2 before shrinking horizontally by 1
3. The
order isn’t important.)

Translate into an algebraic expression and simplify if possible. C It would take Maya x minutes to rake the leaves and Carla y minutes, what portion of the leaves do they rake in one minute if they work together?
Answer:
(x+y)/xy or (1/x + 1/y) portion of the leaves
Step-by-step explanation:
Let the total work done to rake the leaves be a for representation.
Thus,
given Maya takes x minutes to rake the leaves
thus,
work done by may in x minutes = a
dividing both side by x
work done by maya in x/x = 1 minutes = a/x
similarly
given Calra takes y minutes to rake the leaves
thus,
work done by may in y minutes = a
dividing both side by y
work done by maya in y/y = 1 minutes = a/y
__________________________________
Total work done by both in 1 minutes = a/x + a/y = a(1/x+1/y) = a(x+y)/xy
Thus, if a is the total work , then they do (x+y)/xy of a work in one minute.
Thus, (x+y)/xy portion of leaves do they rake in one minute if they work together.

What is average rate of change of function?"It is a measure of how much the function changed per unit, on average, over that interval."
What is the formula average rate of change of function?The average rate of change of function f over the interval a ≤ x ≤ b, is given by this expression: \(\frac{f(b)-f(a)}{b-a}\)
For given question,
We have been given a function \(g ( x ) = 5 x^3 + 4\)
We need to find the average rate of change of function g(x) from x = − 1 to x = 3
Here, a = -1 and b = 3
\(g(a)\\= g(-1)\\=5(-1)^3+4\\=-5+4\\=-1\)
and the value of g(b) is,
\(g(b)\\=g(3)\\=5(3)^3+4\\=135+4\\=139\)
Using the formula of average rate of change of function,
\(\frac{f(b)-f(a)}{b-a}\\\\=\frac{139-(-1)}{3-(-1)}\\\\=\frac{140}{4}\\\\=35\)
Therefore, the average rate of change of \(g ( x ) = 5 x^3 + 4\) from x = − 1 to x = 3 is 35.
