There fore 10 people's high five will be 45 keep repeating and finding out the high fives I got 300 but I'm not sure if it's correct
The required number of high fives is 300.
Given that,
There are 25 students and one teacher in the class. After an exam, everyone high-fives everyone else to celebrate how well they did. How many high-fives were there is to be determined.
In arithmetic, combination and permutation are two different ways of grouping elements of a set into subsets. In a combination, the components of the subset can be recorded in any order. In a permutation, the components of the subset are listed in a distinctive order.
Here,
There are 25 students
n = 25
For each high five, there would be at least 2 students,
r = 2
The number of high five is given by combination,
= 25 C 2
= 25 * 24 / 2
= 600 / 2
= 300
Thus, the required number of high fives is 300.

Tell whether the ordered pair (−1, 4) is a solution of the system.
-2x-3y=-10
-3x+y=7
True or False
Answer:
True because when you substitute the x coordinate to find the value of y =4 and the coordinate is 4
Answer:
True
Step-by-step explanation:
[tex]\left \{ {{-2x-3y=-10} \atop {-3x+y=7}} \right.[/tex]
Rearrange like terms to the same side of the equation:
[tex]\left \{ {{-2x-3y=-10} \atop {y=7+3x}} \right.[/tex]
Substitute into one of the equations:
[tex]-2x-3(7+3x)=-10[/tex]
Apply the Distributive Property:
[tex]-2x-21-9x=-10[/tex]
Combine like terms:
[tex]-11x-21=-10[/tex]
Rearrange variables to the left side of the equation:
[tex]-11x=-10+21[/tex]
Calculate the sum or difference:
[tex]-11x=11[/tex]
Divide both sides of the equation by the coefficient of variable:
[tex]x=-\frac{11}{11}[/tex]
Cross out the common factor:
[tex]x=-1[/tex]
Substitute into one of the equations:
[tex]y=7+3[/tex] × [tex](-1)[/tex]
Calculate:

324 ft
Flagpole
shadow
40 ft
The diagram above shows a 40-foot flagpole and its shadow in relation to a nearby building that is
324 feet tall. If the flagpole's shadow is 50% longer than the flagpole itself, how far is the
building from the flagpole?
The distance between the flagpole and the building is the number of feet between them
The building is 162 feet from the flagpole
How to determine the distanceThe given parameters are:
Flagpole = 40 feetBuilding Shadow = 324 feetThe flagpole's shadow is 50% longer than the flagpole.
So, the length (l) of the flagpole's shadow is:
[tex]l = 40 * (1 + 50\%)[/tex]
[tex]l = 60[/tex]
The length of the building's shadow (d) is then calculated as:
[tex]60 : 40 =d : 324[/tex]
Express as fraction
[tex]\frac{60}{40}= \frac{d}{324}[/tex]
[tex]1.50 = \frac{d}{324}[/tex]
Solve for d
[tex]d = 1.50 * 324[/tex]
[tex]d = 486[/tex]
The distance (x) of the building from the flagpole is then calculated as:
[tex]x = 486 - 324[/tex]
[tex]x = 162[/tex]
Hence, the building is 162 feet from the flagpole

Given y = f(x) and y = g(x), explain the transformations from f(x) to g(x).
shift right then stretch vertically
stretch horizontally then shift down
stretch vertically then shift left
shift up then stretch horizontally
Answer:
shift right then stretch vertically
Step-by-step explanation:
A
The transformations from f(x) to g(x) is shift right then stretch vertically. Hence. option A is the correct answer.
It is Given y = f(x) and y = g(x), we need to explain the transformations from f(x) to g(x).
How does transformation of a function happens?The transformation of a function may involve any change.
These can be shift horizontally (by transforming inputs) or vertically (by transforming output), stretching (multiplying outputs or inputs) etc.
If the original function is y = f(x), assuming horizontal axis is input axis and vertical is for outputs, then:
Horizontal shift (also called phase shift):
Left shift by c units:
y=f(x+c) (same output, but c units earlier)
Right shift by c units:
y=f(x-c)(same output, but c units late)
Vertical shift:
Up by d units: y = f(x) + d
Down by d units: y = f(x) - d
Stretching:
Vertical stretch by a factor k: y = k f(x)
Horizontal stretch by a factor k: y = [tex]f\left(\dfrac{x}{k}\right)[/tex]
Here, the transformations from f(x) to g(x);
We can conclude that the transformations from f(x) to g(x) is shift right then stretch vertically.
Hence. option A is the correct answer.

Allison is saving money to buy a new phone that costs $600 by selling her graphic designs. She is using an app to manage her sales, but it keeps a fraction of each sale. Her net pay is modeled by the function P(x) = x2 + 18x – 160, where x represents the number of sales. How many sales does Allison to make to earn $600?
9 sales
20 sales
38 sales
841 sales
Answer:
20 sales.
Step-by-step explanation:
p(x) = x² + 18x – 160
Here p(x) represents the net pay.
Given that p(x), net pay is $600
x² + 18x – 160 = 600
x² + 18x – 160 - 600 = 0
x² + 18x – 760 = 0
x² +38x - 20x - 760 = 0
x(x+38) - 20(x+38) = 0
(x-20)(x+38) = 0
x = -38, 20
x = 20
Therefore, she makes 20 sales in order to make $600.

2. Consider the equation 3x2 - 13x - 30 = 0.
(a) Write the factored form of the trinomial.
Answer:
(3x + 5)(x - 6) = 0 (Assuming 3x is to the power of two 3x^2)
Step-by-step explanation:
Factor out -13 from -13x
3x^2 - 13(x) - 30 = 0
Rewrite -13 as 5 plus -18
3x^2 + (5 - 18)x - 30 = 0
Apply the distributive property
3x^2 + 5x - 18x - 30 = 0
Now factor out the GCF (Greatest common factor)
To do so we will group the first two terms and last two.
(3x^2 + 5x) - 18x - 30 = 0
Then factor out the GCF from each group.
x(3x + 5) - 6(3x + 5) = 0
(3x + 5)(x - 6) = 0
