The solution is 9x - 36u + 27.
What is the linear equation?
The definition of a linear equation is an algebraic equation in which each term has an exponent of one and the graphing of the equation results in a straight line. An example of a linear equation is y=mx + b.
We have given
-9(-×+4u-3)
When you multiply a negative number by another negative number, the result is positive.
So, to solve this problem, we can use the distributive property and simplify:
-9(-x + 4u - 3) = -9(-x) + -9(4u) + -9(-3)
= 9x - 36u + 27
Hence, the solution is 9x - 36u + 27.

In order to increase the circumference of a circle from 12 pie cm to 18 pie cm, by how much must the diameter increase
Answer: Circumference of a circle is given by the formula C = 2πr, where r is the radius of the circle and π is a constant.
We know that the diameter is twice the radius (d = 2r).
So when we increase the circumference of the circle from 12π cm to 18π cm, we are increasing the radius from r to r'.
To find the increase in diameter, we can use the formula for the diameter, and subtract the original diameter from the new diameter.
d' = 2r' and d = 2r
d' - d = 2r' - 2r
We know that the relationship between circumference and radius is C = 2πr.
So we can write:
12π = 2πr and 18π = 2πr'
r = 6/π and r' = 9/π
then
d' - d = 2r' - 2r = 2(9/π) - 2(6/π) = 18/π - 12/π = 6/π
Therefore, the diameter must increase by 6/π cm in order to increase the circumference of the circle from 12π cm to 18π cm.

here are 15 European cities that Yolanda would eventually like to visit. On her next vacation, though, she only has time to visit 3 of the cities: one on Monday, one on Tuesday, and one on Wednesday. She is now trying to make a schedule of which city she'll visit on which day. How many different schedules are possible? (Assume that she will not visit a city more than once.)
The number of different schedules are possible is given by the permutation and the equation is P = 2,730 schedules
What are Permutations?A permutation is an ordered arrangement.
The number of ordered arrangements of r objects taken from n unlike objects is:
Permutation ⁿPr = n! / ( n - r )!
Given data ,
Let the total number of schedules be P
Let the total number of European cities be n = 15
Let the number of cities Yolanda can visit in time r = 3 cities
So , the total number of different schedules is calculated by permutation and ,
The total number of different schedules = ⁿPr = n! / ( n - r )!
Substituting the values in the equation , we get
¹⁵P₃ = ( 15 ) ! / ( 15 - 3 ) !
¹⁵P₃ = ( 15 ) ! / ( 12 )!
¹⁵P₃ = 15 x 14 x 13
¹⁵P₃ = 2,730 schedules
Hence , the value of P is 2,730 schedules

At an amusement park, only 17 people are allowed on a ride at the
same time. There are 157 people waiting in line. How many groups
of riders will there be?
Show your work.
Answer:
To find out how many groups of riders there will be, we need to divide the total number of people waiting in line (157) by the maximum number of people allowed on the ride at one time (17).
157 people / 17 people/group = 9.235 groups (approx)
But since the groups must be in whole numbers, we have to round up the value 9.235 groups to the next whole number, which is 10 groups.
So, the number of groups of riders will be 10.
Answer: 9 groups of riders.
Step-by-step explanation:
To find out how many groups of riders there will be, you need to divide the total number of people waiting in line by the maximum number of people allowed on the ride at one time.
157 (total people in line) ÷ 17 (people allowed per ride) = 9.235 (groups of riders)
Because you can't have a fraction of a group, you need to round down to get the whole number of groups.
So the answer is 9 groups of riders.

Verify that [n+3]!\n!=(n+1
Answer:
To verify that [n+3]! / n! = (n+1), we can use the definition of factorial:
[n+3]! = (n+3) * (n+2) * (n+1) * n!
And we can cancel out n! from both sides of the equation:
(n+3) * (n+2) * (n+1) = n+1
Which is true, and thus [n+3]! / n! = (n+1) holds true.
Another way to verify this is by simplifying the RHS and LHS
(n+1) = (n+1)
And the LHS,
(n+3)! = (n+3)(n+2)(n+1)n! = (n+1)(n+2)(n+3)n! = (n+1)(n+2)(n+3)!/n!
which is also equal to (n+1)
So, [n+3]! / n! = (n+1) is true.

To figure out what percentage of the trail mix is chocolate, we add up all the pieces, divide the number of chocolate pieces by the total and multiply by 100. In this case, we find that 35% of the trail mix is chocolate.
Explanation:In order to figure out the percent of chocolate pieces in Caitlyn's trail mix, we first need to determine the total number of pieces. Caitlyn counts 28 raisins, 28 chocolate pieces, and 24 peanuts, which gives us a total of 80 pieces in the mix. Then, since there are 28 chocolate pieces, we divide 28 (chocolate pieces) by 80 (total pieces). This will give us the decimal representation of the portion of the mix that is chocolate. To convert this into a percentage, we multiply by 100. Hence, the calculation will be (28/80)*100 = 35%. So, 35% of the trail mix is chocolate.

Square ABCD has a diagonal AC with the given vertices. Find the coordinates of the remaining vertices.
A(-4,-1) and C(2,5)
The coordinates are ( , ) and ( , )
Answer: To find the coordinates of the remaining vertices of square ABCD, we can use the information we have been given about the diagonal AC and its vertices. The diagonal AC has been given as having the vertices A(-4, -1) and C(2, 5). Since a square has right angles, we know that the other two vertices of the square must form a right angle with the diagonal AC.
To find the coordinates of vertex B, we know that it must have the same y-coordinate as vertex A, but a different x-coordinate. Since the x-coordinate of vertex A is -4, we can deduce that the x-coordinate of vertex B must be the same as the x-coordinate of vertex C, which is 2. Therefore, the coordinates of vertex B are (2, -1).
To find the coordinates of vertex D, we know that it must have the same x-coordinate as vertex A, but a different y-coordinate. Since the y-coordinate of vertex A is -1, we can deduce that the y-coordinate of vertex D must be the same as the y-coordinate of vertex C, which is 5. Therefore, the coordinates of vertex D are (-4, 5).
In summary, the coordinates of the remaining vertices of square ABCD are B(2, -1) and D(-4, 5)

Square ABCD has a diagonal AC with the given vertices. Find the coordinates of the remaining vertices.
A(-3, 2) and C(0,5)
The coordinates are ( , ) and ( , )
The coordinates of the remaining vertices exists (2√(13),1) and (-2, 4√(13)).
What is meant by coordinates?A group of values that exhibit precise positioning The first number on a graph represents the distance along, while the second number represents the distance up or down.
To find the coordinates of the remaining vertices of square ABCD, we can use the information given about diagonal AC and the properties of a square. Since a square has equal side lengths and right angles, we know that the distance between opposite vertices on a diagonal must be equal to the side length of the square.
Given the coordinates of vertex A and C, we can use the distance formula to find the length of AC :
Let the equation be Distance [tex]$d=\sqrt{\left(x_2-x_1\right)^2+\left(y_2-y_1\right)^2}$[/tex] substitute the values in the above equation, we get
[tex]$\mathrm{AC}=\sqrt{\left((2-(-2))^2+(4-1)^2\right)}$$[/tex]
simplifying the equation, we get
[tex]$A C=\sqrt{ }(4+9)=\sqrt{ }(13)$$[/tex]
We can utilize the knowledge of the square's side length to determine the locations of the remaining vertices. Vertex B is known to have the same y-coordinate as vertex A, while vertex C is two units to the left in terms of the x-coordinate. Therefore, the coordinates of vertex B exists (-2 + 2√(13), 1).
Similar to vertex A, vertex D is known to have an identical x-coordinate, but its y-coordinate is four units below vertex C. Therefore, the coordinates of vertex D exists (-2, 4√(13))
Therefore, the coordinates of the remaining vertices exists (2√(13),1) and (-2, 4√(13)) respectively.
