Answer: Option 2
The line starts at an x of -4, so the domain is from -4 to infinity since the arrow goes off the graph, meaning it keeps going. The line starts on a y of 2, and the line continues up with the arrow pointing slightly up, so the range is from 2 to infinity.
The domain is from left to right, and the range is down to up
Answer:
2. {x | x ≥ −4}; {y | y ≥ 2}
Step-by-step explanation:
Let's try to determine the domain first. Look at the x values. The function begins at -4, so our possible domain values also begin at -4, and the values continue positively after -4.
Therefore, our domain is: Domain: {x ≥ -4}.
Or, we could assign our domain using interval notation: [-4,infinity).
Our range, or y values, begin at 2 and continue positively after 2.
Therefore, our range is: Range: {y ≥ 2}.
Again, we could use interval notation to assign our range: [2,infinity)
Therefore, the answer would be
2. {x | x ≥ −4}; {y | y ≥ 2}

If we multiply three consecutive integers and then add the middle number to the result, the answer is always the middle number cubed.
5 × 6 × 7 + 6 = 216 = 63
10 × 11 × 12 + 11 = 1331 = 113
15 × 16 × 17 + 16 = 4096 = 163
Use what you have learned in this lesson to write a third-degree polynomial expression in factored form and standard form that represents this pattern. Show that the factored form is equivalent to the expression written in standard form. Substitute three different values for the variable to prove this pattern works for other numbers.
Step-by-step explanation:
Let use have a interger,n
Thus three consectice intergers can be represented by
[tex]n[/tex]
[tex]n + 1[/tex]
[tex]n + 2[/tex]
Multiply, and we get
[tex]n(n + 1)(n + 2)[/tex]
[tex]n( {n}^{2} + 3n + 2)[/tex]
[tex]n {}^{3} + 3 {n}^{2} + 2n[/tex]
Then add the middle number, n+1.
[tex] {n}^{3} + 3n {}^{2} + 3n + 1[/tex]
We must prove that the middle number cubed = the equation.
Using the binomial theroem,
[tex](n + 1) {}^{3} = {n}^{3} + 3( {n}^{2} 1 {}^{1} ) + 3n( {1}^{2} ) + 1 {}^{3} [/tex]
[tex](n + 1 ){}^{3} = {n}^{3} + 3 {n}^{2} + 3n + 1[/tex]
So this is indeed true.
You can do the subsitue variables for n to prove it.

Given the functions f(x) = 6x 11 and g(x) = x2 6, which of the following functions represents f[g(x)] correctly? f[g(x)] = 36x2 132x 127 f[g(x)] = 36x2 132x 121 f[g(x)] = 6x2 47 f[g(x)] = 6x2 36.
Function defines relationship between variables. The value of the f[g(x)] when the value of f(x)=6x+11 and g(x)=x²+6 is f[g(x)]= 36x²+47.
What is a function?A function assigns the value of each element of one set to the other specific element of another set.
Given to us
f(x) = 6x + 11
g(x) = x² + 6
As we know the two functions, given to us f(x) = 6x + 11, therefore substitute the value of x as g(x) in order to find the value of f[g(x)] ,
[tex]f(x) = 6x + 11\\\\f[g(x)] = 6(x^2 + 6) + 11\\\\f[g(x)] = 6x^2 + 36 + 11\\\\f[g(x)] = 6x^2 + 47[/tex]
Hence, the value of the f[g(x)] when the value of f(x)=6x+11 and
g(x)=x²+6 is f[g(x)]= 36x²+47.

Solve by the elimination method. Check your work.
Answer:
1: x = 19 y = 16 ; 2. x = 5 y = -4
Step-by-step explanation:
To check your work plug the numbers back into one of the equations and see if it's true.
For example:
10(19)-9(16)=46
46=46
1. I distributed 3 to all the numbers so that 9y and -9y would cancel then you add like terms.
2. I distributed -4 to all the numbers so that 4x and -4x would cancel. Then add all like terms.
Once you get x or y plug it back into one problem to get the other variable.

The experimental probability of winning a game is 2/7. How many times can you expect to win the game if you play 56 times?
Question options:
7
56
16
8
Answer:
You would expect to win the game 16 times.
Step-by-step explanation:
I set up a proportion for this :
2/7 = x/56
2(56) = 7x (cross multiply)
112 = 7x (multiply 2 and 56)
x = 16 (divide 7 from both sides)

someone can help me for all the question ?
Answer:
1. 5
2. 3 adult tickets; 2 child tickets
3. See below
Step-by-step explanation:
1.
2 adult tickets cost 2 × $12 = $24
Subtract $24 from $64:
$64 - $24 = $40
Divide $40 by $8:
$40 ÷ $8 = 5
Answer: 5 child tickets
2.
x = number of adult tickets
y = number of child tickets
The total number of tickets is 5, so the first equation is:
x + y = 5
The cost of x adult tickets is 12x. The cost of y child tickets is 8y. The total cost is 12x + 8y. We are told the total cost is $52. The second equation is:
12x + 8y = 52
The system of equation is:
x + y = 5
12x + 8y = 52
Let's solve it by substitution.
Solve the first equation for x.
x = 5 - y
Now we substitute x in the second equation by 5 - y.
12(5 - y) + 8y = 52
Distribute:
60 - 12y + 8y = 52
Combine like terms on the left side:
-4y + 60 = 52
Subtract 60 from both sides:
-4y = -8
Divide both sides by 4.
y = 2
Substitute y = 2 in the first original equation and solve for x.
x + y = 5
x + 2 = 5
x = 3
Answer: 3 adult tickets; 2 child tickets
3.
The customer's claim is incorrect. His sum is $71. 71 is an odd number. Since all ticket prices are even numbers, it is impossible to add only even numbers and get an odd sum. A sum of several amounts of 12 and several amounts of 8 can never equal 71.
We can also show his claim is false using a system of equations.
x + y = 7
12x + 8y = 71
Use substitution.
x = 7 - y
12(7 - y) + 8y = 71
84 - 12y + 8y = 71
84 - 4y = 71
-4y = -13
y = 3.25
This means 3.25 child tickets. The problem states that tickets can be purchased only in whole numbers, so 3.25 tickets cannot be purchased, so the customer's claim is false.
