Does the expression x^3-1 divided by x^2 -1 simplify to x?
No, the expression (x^3 - 1) / (x^2 - 1) does not simplify to x.
To simplify the expression, let's first factorize both the numerator and denominator.
The numerator can be factorized using the difference of cubes formula: a^3 - b^3 = (a - b)(a^2 + ab + b^2). So, we have (x^3 - 1) = (x - 1)(x^2 + x + 1).
The denominator is a difference of squares: a^2 - b^2 = (a - b)(a + b). Therefore, (x^2 - 1) = (x - 1)(x + 1).
Now, we can simplify the expression by canceling out the common factors in the numerator and denominator:
[(x - 1)(x^2 + x + 1)] / [(x - 1)(x + 1)]
The (x - 1) terms cancel out, leaving us with:
x^2 + x + 1 / (x + 1)
So, the simplified form of the expression is (x^2 + x + 1) / (x + 1), which is not equal to x.

Step-by-step explanation:
the equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
equation of blue line is y = x + 2 , in slope- intercept form
with slope m = 1
equation of red line is y = x - 3 , in slope- intercept form
with slope m = 1
• Parallel lines have equal slopes
then the blue and red lines are parallel.
the solution to the system is at the point of intersection of the 2 lines
since the lines are parallel then they do not intersect each other.
thus the system shown has no solution.

Consider this equation. cos(0) = 4√47/41.
If 0 is an angle in quadrant IV, what is the value of sin(0)
Therefore, sin(0) = -√305/41 when 0 is an angle in quadrant IV.
What is trigonometry?Trigonometry is a branch of mathematics that deals with the study of relationships between the angles and sides of triangles. It is used to solve problems in many fields, including engineering, physics, astronomy, and architecture. Trigonometry involves the use of functions such as sine, cosine, and tangent to relate the angles and sides of a right triangle. It also includes the study of trigonometric identities, equations, and graphs, as well as applications of trigonometry in real-world situations.
Here,
If 0 is an angle in quadrant IV, then cosine is positive and sine is negative. We can use the Pythagorean identity to find the value of sin(0):
sin²(0) + cos²(0) = 1
sin²(0) = 1 - cos²(0)
sin(0) = -√(1 - cos²(0))
substituting the given value of cos(0):
sin(0) = -√(1 - (4√47/41)²)
sin(0) = -√(1 - (16*47/41))
sin(0) = -√(1 - 736/41)
sin(0) = -√(305/41)
sin(0) = -(√305)/√(41)

Step-by-step explanation:
one card is drawn from a pack of 52cards each of the 52 cards being equally likely to be drawn. what is the probability that the card drawn is a king?
The probability of drawing a king from a standard deck of 52 cards is 1/13.
In a standard deck of 52 playing cards, there are four kings: the king of hearts, the king of diamonds, the king of clubs, and the king of spades.
To find the probability of drawing a king, we need to determine the ratio of favorable outcomes (drawing a king) to the total number of possible outcomes (drawing any card from the deck).
The total number of possible outcomes is 52 because there are 52 cards in the deck.
The favorable outcomes, in this case, are the four kings.
Therefore, the probability of drawing a king is given by:
Probability = (Number of favorable outcomes) / (Number of possible outcomes)
= 4 / 52
= 1 / 13
Thus, the probability of drawing a king from a standard deck of 52 cards is 1/13.
This means that out of every 13 cards drawn, on average, one of them will be a king.
It is important to note that the probability of drawing a king remains the same regardless of any previous cards that have been drawn or any other factors.
Each draw is independent, and the probability of drawing a king is constant.

A food truck vendor sells small drinks for $1.15, medium drinks for $1.75, and large
drinks fro $2.25. The vendor sold a total of 1,385 drinks for a full week of business.
During the same week, his total sales were $2,238.75. During the week, he also sold
twice as many small drinks as medium drinks. Write a 3X3 system of equations that
models the vendors situation. Use s for small drinks, m for medium drinks, and g for
large drinks.
The system of equations is given by :
s + m + g = 1385
1.15 s + 1.75 m + 2.25 g = 2238.75
s = 2m
A group of equations comprising one or more variables is known as a system of equations. The variable mappings that satisfy each component equation, or the points where all of these equations cross, are the solutions of systems of equations.
We shall employ the linear combination method to resolve a system of three equations in three variables. This time, we will solve for the third variable while eliminating the second variable using the equations that follow from the elimination of the first.
Given the number of small drinks by the vendor is s , number of medium drinks is m and the number of large drinks is g.
The vendor sold all three drinks total of 1385, hence the equation:
∴ s + m + g = 1385.
Each small drink costs 1.15 , medium drinks cost 1.75 and large drinks cost 2.25, hence the equation:
∴ 1.15 s + 1.75 m + 2.25 g = 2238.75
He sold twice as many small drinks as medium drinks, hence the equation:
∴ s = 2m
The system of equations is given by:
s + m + g = 1385
1.15 s + 1.75 m + 2.25 g = 2238.75
s = 2m

a profit of 24% was made wheb a book was sold for birr 34% find the selling price that would have given a profit 28%
Answer:
$35.20
Step-by-step explanation:
Given that the profit of 24% was made on $34.10,
And Profit = Selling price - cost price,
Where profit is 24%, and selling price is $34.10, cost price = ?
Then, to find the cost price (z):
Assume the cost price be a 100% and the selling price of $34.10 be 124%
Hence, we have
$34.10 = 124%
z = 100%
Substitue
=> z / 34.10 = 100% / 124 %
=> 124z = 34.10 (100)
124z = 3410
Divide both sides by the coefficient of z which is 124
z = $27.50
Therefore, to find the selling price for a profit of 28%
We have 28% of 27.5 = 7.70
With equation of Profit = Selling price - cost price
We have 7.70 = Selling price - 27.50
Removing 7.7 from both sides
We have, Selling price = 27.50 + 7.70
=> Selling price = $35.20
Hence, the selling prices for a profit of 28% is $35.20

The length of line having mid point B ⇒ 7x - 2.
Given that,
B is the mid point of AC
And also given that
length of segment AB = 2x+5
And length of segment BC = 5x - 7
A straight path established by linking a group of points in a plane is known as a line. It is a one-dimensional form with only a length and no width or height. A line can extend indefinitely in both ends in opposite directions. To indicate a line, we can use upper case characters.
Now since B is the mid point of AC,
So, The line AC is sum of the line segment AB and line segment BC.
Therefore,
AC = AB+BC
= (2x+5)+(5x - 7)
= 7x - 2
Hence,
The length of AC is 7x - 2

What is the meaning of "A group G whose order is a prime number has only two subgroups, G itself and 1 = {1}"?
If G is not a cyclic group, then it does not have a subgroup of order p. Conversely, if G is cyclic, then it has a unique subgroup of order p.
The statement "A group G whose order is a prime number has only two subgroups, G itself and 1 = {1}" means that if G is a group with a prime number of elements, then the only subgroups of G are the trivial subgroup {1} and the group G itself.
In other words, there are no other proper subgroups of G besides these two.
The statement "A group G whose order is (p-1) where p is a prime number has a subgroup of order p if and only if G is cyclic" means that if G is a group with (p-1) elements, where p is a prime number, then G has a subgroup of order p if and only if G is a cyclic group.
In other words, if G is not a cyclic group, then it does not have a subgroup of order p. Conversely, if G is cyclic, then it has a unique subgroup of order p.
