An example of substitution property is finding the solution of an algebraic expression.
The substitution property is a notion in algebra that is used for substituting the value of a given variable or a quantity into an expression to find the value of the unknown.
In other words, we can express that the substitution property is utilised to replace the value of a quantity in an equation or an expression to solve a mathematical problem.
For example, Find the value of the algebraic expression x² - 3x + 8 if x = 1.
Using the substitution property, we will substitute x with 1 in the given expression to find its value.
x² - 3x + 8 if x = 1
= 12 - 3(1) + 8
= 1 - 3 + 8
= -2 + 8
= 6
So, the value of the given algebraic expression x² - 3x + 8 is 6 when x = 1.

How do you find the value of N example?
N! also called N factorial is the product of all positive non-integers equal to or less than N or simply is the product of the Nth integer and all integers below it.
N! is represented as 1x2x3x4.......x n which is also equivalent to n x (n-1_x(n-2w)x(n-3)......x1. Therefore the formula for N factorial is N! = n × (n - 1)!. For whole numbers, the factorial is a product of natural numbers till 1 of the values is equal to or less than whole numbers.
N is also used to represent the set of natural numbers up to infinity. Natural numbers include the values from till infinity, they can be represented like N=[1,2,3,4,5,6........].
Examples of N! are:-
4!= 4x3x2x1=24 here we take the product of values equal to or less than 4 upto 112= 12x11x10x9x...... x2x1=479001600 here we calculate the product of 12 and lesser natural numbers(N+3)!= (N-3)X(N+2)X(N+1)X......X1To know more about factorials visit:

System of Equations:
Brooklyn could calculate how many arithmetic problems she completed and how many pages she read using the equations x = 2y and 2x + 3y = 70.
What is meant by mathematical equations?An algebraic expression in mathematics is an expression created using variables, constant algebraic numbers, and algebraic operations. A good example of an algebraic expression is 3x2 2xy + c.Algebraically speaking, an equation is a statement that shows the equality of two mathematical expressions.For instance, the two equations 3x + 5 and 14, which are separated by the 'equal' sign, make up the equation 3x + 5 = 14.let
number of math problems Brooklyn solved = x
number of pages she read = y
Time to solve each math = 2 minutes
Time to read each page = 3 minutes
Brooklyn read twice as many pages as there were arithmetic problems to be done.
x = 2y
2x + 3y = 70
Substitute x = 2y into
2x + 3y = 70
2(2y) + 3y = 70
4y + 3y = 70
7y = 70
divide both sides by 7
y = 70/7
y = 10
Recall,
x = 2y
x = 2(10)
x = 20
Therefore, Brooklyn completed 20 math problems and read 10 pages, which equals 20 math problems and 10 pages, respectively.

If a quadratic function has a turning point of (-3, 2)
then where does the quadratic function defined by
g(x) = 2f(x-4) + 5.
a) Describe the transformations(s).
b) State the turning point of g(x).
a) The quadratic function g(x) = 2f(x-4) + 5 is defined as a transformed version of the original quadratic function f(x). The transformation applied to f(x) is a horizontal shift of 4 units to the left and a vertical shift of 5 units upward. This can be observed from the fact that x is replaced with (x-4) in the function g(x). The function is also scaled by a factor of 2.
How does a quadratic function work?
f(x) = ax2 + bx + c, where a, b, and c are numbers and an is not equal to zero, is a quadratic function. A parabola is the shape of a quadratic function's graph. Although the "width" or "steepness" of a parabola can vary as well as its direction of opening, they all share the same fundamental "U" form.
b) The turning point of the quadratic function f(x) is (-3, 2). To find the turning point of g(x), we must first apply the horizontal shift of 4 units to the left to the x-coordinate, and then apply the vertical shift of 5 units upward to the y-coordinate.
The turning point of g(x) is (-3+4, 2+5) = (1,7)
So, the turning point of the transformed function g(x) is (1,7)
We can see that the transformation of g(x) moves the turning point of f(x) to the right and up, as expected from the transformation.

What is mean?Regardless of whether many elements are discrete or continuous, averages can only be calculated for numeric variables. You may find this by dividing the total number of values in the dataset by the total number of values in the dataset. It is possible to perform computations using either raw data or data that has been compiled into frequency tables. The average value in mathematics is obtained by adding up all the numbers in a set of data and dividing the total by the total number of numbers.

We multiply by -3/2 to get rid of y and figure out the system of equations.
What are equations?A mathematical assertion that has an "equal to" symbol between two expressions with equivalent values is called an equation.
As in 3x + 5 Equals 15, for instance.
Equations come in a variety of forms, including straight, quadratic, cubic, and others.
So, we have:
9x+3/4y=6 and 2x+1/2y=9
By removing y, we must solve a system of equations.
Therefore, we will first make the y-coefficient equal but with the opposite sign.
In the first equation, the y-coefficient is 3/4
The coefficient of y in equation two is half.
LCM: 3/4 and 1/2 = 3/2
To maintain the same coefficient of y, multiply the second equation by -3/2.
-3/2*2x-3/2*1/2y = -3/2*9
-3x-3/4y = -27/2
9x+3/4y = 6
Combine the two equations and get rid of the y variable.
-3x+9x = -27/2+6

A map uses scaled drawings. The distance between the two considered cities on that specified map is 6.25 inches
How are scale drawings formed?
For a particular scale drawing, it is already specified that all the measurements' some constant scaled version will be taken. For example, let the scale be K feet to s inches.
Then it means
1ft : s/k in.
All feet measurements will then we multiplied by s/k to get the drawing's corresponding lengths.
For this case, it is specified that the map uses scaling such that:
3/4 of an inch on map = 3 miles in reality.
Dividing both the quantities by 3, we get:
1 mile in reality = 3/4 / 3 inches on map = 1/4 inches on map
Multiplying both the quantities by 25, we get:
25 miles in reality = 25/4 = 6.25 in map
Since 25 miles is the distance between those two considered cities.

Can someone help me with these pls
Answer:
9) 17 miles/hr
10) 7.14 miles
Step-by-step explanation:
See the attached worksheet. Note the use of conversion factors. In question 9 we want to convert minutes to hours. We know there are 60 minutes/hr. So we can set up a conversion factor in one of 2 ways: (60 minutes/1 hr) or (1 hr/60 minutes). Both are valid, and both are = 1, since the numerator and denominator are both equivalent. This means we can invert a conversion factor and it is still = 1. Since conversion facots are equal to 1, we can multiply them times anything, and the result is numerically the same (anything times 1 = anything) and only the units have changed. For question 9, we want to convert miles/min to miles/hr. I'll choose the conversion factor (60 min/1 hr), mostly because I like multiplication over division. Note how the units cancel in the attachment, resulting in 17 miles/hr. One may also use the factor (1hr/60min), but then a division is required. Perfectly fine, but not my preferred route.
The same approach is used to answer question 10. Again, note how he units cancel, leaving a number wth just the units desired,
