The algebraic expression that represents the total amount of money in terms of x is:
y = 45*x + 20
How to write the algebraic expression?Here we want to find the total value (in cents) of:
x quarters.x + 2 dimes2x nickels.The total value will be given by the linear equation:
y = x*25 + (x + 2)*10 + (2x)*5
Where y represents the total value in cents.
Now we can simplify that equation to get:
y = x*25 + (x + 2)*10 + (2x)*5
y = x*25 + x*10 + 20 + x*10
y = 45*x + 20
This is the algebraic expression we wanted to get.

A plane is a two-dimensional doubly ruled surface spanned by two linearly independent vectors.
And then the intersection of the plane becomes:
Then
The intersection of two planes is a line. If the planes do not intersect, they are parallel.
They cannot intersect at only one point because planes are infinite.it means parallel planes have no intersection point.

By inductive reasoning we can say that the conclusion is based on observing the four numbers in the sequence.
How to use Inductive Reasoning?
We are given the arithmetic series as;
5, 10, 15, 20, .......
From the formula of the nth term of an arithmetic series, we know that;
a_n = a + (n - 1)d
where;
a is first term
n is position of term
d is common difference
Thus, for this series, it is clear that the common difference is 5. Thus the fifth term is;
a_5 = 5 + (5 - 1)5
a_5 = 5 + 20
a_5 = 25
Thus, by inductive reasoning we can say that the conclusion is based on observing the four numbers in the sequence.

you buy x packs of pencils, twice as many packs of erasers, and three times as many rolls of tape. write an expression in simplest form for the total amount spent.
pencils cost 1.85
erasers cost 3.15
tape cost 2.50
Items purchased:
x packs of pencils,
twice as many packs of erasers, total number of eraser packs = 2x
three times the number of tape rolls, number of tape rolls = 3x
total expenditure = x m + 2xn + 3xp = x(m + 2n + 3p)
We now have two possibilities:
1- All three goods are the same price:
cost of one pencil pack = cost of one eraser pack = cost of one roll of tape = m
x m + 2xm + 3xm = 6xm
total amount spent
2- The three goods are not the same price:
m = the cost of one pencil pack
n = the cost of one pack of erasers
One roll of tape costs p.
total expenditure = x m + 2xn + 3xp = x(m + 2n + 3p)

Answer: 144
Step-by-step explanation:
Function yes or no what is the domain and range
Step-by-step explanation:
I assume the grid units are single units (1, 2, 3, ...).
to be a function every value of x must have exactly one value of y.
but that is violated at x = 2. at that point y can be either +3 or -3 (indicated by the 2 points at x=2).
so, no, it is not a function.
the domain is the interval or set of all valid x (input) values.
since we have no continuous curve but single points, it is a set :
x € {-4, -3, -2, 1, 2, 3, 6}
the range is the interval or set of all valid y (function result) values. again, it is a set for the same reasons :
y € {-3, -2, 0, 1, 3, 4}

Given [tex]f(x)=x^2-1[/tex] and [tex]g(x)=\sqrt{x-8}[/tex], then
[tex]f\circ g (x) = f(g(x)) = f(\sqrt{x-8}) = \left(\sqrt{x-8}\right)^2 - 1 = \boxed{x - 9} \neq x[/tex]
so right away we know [tex]f[/tex] and [tex]g[/tex] are not inverses.
In the other direction, we come to the same conclusion.
[tex]g\circ f(x) = g(f(x)) = g(x^2 - 1) = \sqrt{(x^2-1)-9} = \boxed{\sqrt{x^2 - 9}} \neq x[/tex]

The fluid force against the window is equal to 931.5 lb.
Given the following data:
Width of viewing portion = 69 inches.Dimension of fish tank = 69 × 28.5 × 1.5 inches.Density of seawater = 64 lb/ft. Thickness of glass = 3/4 inch.How to calculate the fluid force against the window?Generally speaking, the fluid force that is exerted on the fish tank by the seawater is due to the liquid pressure acting over the given area. Also, the fluid force that is exerted on the fish tank is directly proportional to the depth of seawater.
The depth of seawater is given by:
Depth = 28.5 - 1.5
Depth = 27 inches.
Next, we would convert the unit of the depth of seawater and width of viewing portion in inches to feet:
1 inch = 12 feet
Depth = 27 inches to feet = 27/12 = 2.25 feet.
Width = 69/12 = 5.75 feet.
Now, we can calculate the fluid force against the window by using this formula:
Fluid force = (density × depth × width)/2
Fluid force = (64 × 2.25² × 5.75)/2
Fluid force = 1863/2
Fluid force = 931.5 lb.

A reflection followed by rotation
B. translation followed by rotation
C. translation followed by reflection

D.
The drawing shows a series of transformations and the sequence that moves Triangle I to Triangle II to Triangle III is translation followed by reflection.
A reflection in arithmetic is a form of geometrical transformation, wherein an item is flipped to create a reflect or congruent image. The bisector of the plane is referred to as the definition on the line of reflection, and it is perpendicular to the preimage and photograph.
In the coordinate plane we will draw the translation if we recognize the path and how far the figure have to be moved. To translate the factor P(x,y) , a units right and b units up, use P'(x+a,y+b) .
A translation is a form of transformation that takes every factor in a figure and slides it the equal distance in the equal path.
Here, the image is first translated and then rotated.
Therefore, the drawing shows a series of transformations and the sequence that moves Triangle I to Triangle II to Triangle III is translation followed by reflection.

2.) A rectangular garden is 6 ft longer than it is wide. Its area is 352 ft2. What are its dimensions?
Answer:
Length = 22, Width = 16
Step-by-step explanation:
Let L be the length of the garden and W the width
The area, A = L x W = 352 ft²
It is given that L = W + 6
Substituting for L in the area equation we get
L x W
==> (W + 6) x W = 352
Expanding the brackets
==> W.W + 6.W = 352
==> W² + 6W = 352
Subtract 352 from both sides:
W² + 6W - 352 = 0
This is a quadratic equation which can be solved using the quadratic formula.
- 352 = - 16 x 22 and -16 + 22 = 6
So we can factor the quadratic equation as
(W - 16) (W + 22) = 0
==> W = 16 or W = -22
Since we can disregard negative values in this context,
W = 16 and L = W + 6 = 16 + 6 = 22
Dimensions are Length = 22, Width = 16

You know the sum of -5 and another integer is a positive integer. What can you conclude about the sign of the other integer? What can you conclude about the value of the other integer. Explain.
The sign of the other integer is positive. Value of other integer is greater than 5.
When we add two numbers of the same sign, final number has the same sign of the initial numbers
For example, we add 3 and 8,
3+8= 11
Both the numbers 3 and 8 are positive so our result is also positive.
On the other hand when we add -3 and -8, then the result will be
-3 +(-8)= -11
Both the numbers are negative, so our result also negative.
When two numbers of different sign are being added then the sign of the larger number decide the sign of the final number
For example, we add -3 and 8.
-3+8= 5
8 is larger than 3, and has positive sign, so the result will also be positive.
Suppose other number is x.
-5+x>0 (As the sum is positive)
Add 5 on both the sides
-5+x+5>0+5
x>5
As we can see the number is greater than 5 and has a positive value.
Final answer: The sign of the other integer is positive. Value of other integer is greater than 5.
