Well, "minus 6 x cubed minus y squared minus 3 x y" translates to:
[tex]-6x^{2} -y^{2} -3xy[/tex]
Then, if we insert the values for x and y, we get:
[tex]-6(-2)^{2} -(4)^{2} -3(-2)(4)[/tex]
When we distribute and multiply:
[tex]144-16-24[/tex]
And once we combine like terms:
104 is the answer
The given statement can be written in expression form as
[tex]-6x^3-y^2-3xy[/tex]
As the value of [tex]x=-2[/tex] and [tex]y=4[/tex] are given .
To find the value of expression at the given values of [tex]x[/tex] and [tex]y[/tex] , we have to insert the values into the expression
[tex] -6(-2)^3-(4)^2-3(-2)(4)[/tex]
Now solving by cubing and squaring the numbers
[tex]-6(-8)-16-3(-8)[/tex]
As negative negative is positive and positive negative is negative
[tex] 48-16+24[/tex]
Adding like terms and subtracting we get

I need to know what 11, 14, and 15 are I don't remember how to do it
When you reflect a function in the x-axis, the first coordinate of a point stays the same, and the second coordinate changes sign (what was positive is now negative and vice versa). See the attached picture.
Question 11: f(x) = -5x + 2. The function changes to its opposite, so g(x) = -(-5x + 2) = 5x - 2.
When you reflect a function in the y-axis, the first coordinate of a point changes to its opposite, but the second coordinate stays the same. Replace x with -x .
Question 14: f(x) = |2x - 1| + 3. Replacing x with -x produces g(x) = |2(-x) - 1| + 3 which simplifies to g(x) = |-2x -1| + 3.
Question 15 works the same way as #14.
what are the x and y intercepts of the function f(x)=3x+6
x-intercept = - 2 , y-intercept = 6
to find the intercepts, that is where the graph crosses the x and y axes
• let x = 0, in the equation for y-intercept
• let y = 0, in the equation for x-intercept
x = 0 : y = 0 + 6 = 6 ⇒ (0, 6 ) is the y-intercept
y = 0 : 3x + 6 = 0 ⇒ x = - 2 ⇒ (- 2, 0 ) is the x-intercept
A man who is 6 feet tall casts a shadow that is 11 feet long. At the same time, a tree casts a shadow that is 33 feet long. What is the height of the tree?

6/11 = x/33
198 = 11x
x = 18
The height of the tree is 18 feet tall
The height of the tree will be 18 feet.
What are ratio and proportion?A ratio is an ordered set of integers a and b expressed as a/b, with b never equaling 0. A proportional is a mathematical expression in which two things are equal.
A man who is 6 feet tall casts a shadow that is 11 feet long.
At the same time, a tree casts a shadow that is 33 feet long.
Then the height of the tree will be
Let x be the height of the tree.
Then we have

I need help with a question before my test: how do I tell if a graph has rotational Symmetry if it is not an odd function and do all odd functions have point symmetry??
Answer:
If you know that the function is not odd, you know that the graph does not have rotational symmetry
Step-by-step explanation:
There is a theorem that says: "A function is odd if, and only if, its graph is symmetric with respect to the origin, or it has rotational symmetry in 180 ° with respect to the origin"
This statement is equivalent to:
If a function is odd, its graph has rotational symmetry with respect to the origin
If a graph has rotational symmetry with respect to the origin then the function is odd.
Therefore, it is impossible for the graph to have rotational symmetry with respect to the origin and the function is not odd.
Then, if you know that the function is not odd, you know that the graph does not have rotational symmetry
And arithmetic sequence has a first term of 10 and the sixth term of 40. What is the 20th term of the sequuence?
Solution
The general form of the n-th term = a + (n-1)d
Here we are given the 1st term (a) = 10
6th term = 40
We need to find the 20th term.
Let's find the common difference.
6th term = 10 + (6 - 1) d
6th term is 40, so
40 = 10 + (6 -1)d
40 -10 = 5d
30 = 5d
d = 30/5
d = 6
The common difference is d = 6.
20th term = a + (n -1)d
= 10 + (20 -1)6
= 10 + 19*6
= 10 + 114
20th term = 124

Type the correct answer in the box. Fill in the missing term in the equation. (1 + 2i)(2 + i) + = 5(2 + i)
To solve the complex number equation and find the missing term, we first multiply (1 + 2i)(2 + i), simplify, and then compare it to the expanded form of 5(2 + i). The missing term is found to be 10.
Explanation:The student is working on a complex number multiplication and addition problem.
The initial equation is (1 + 2i)(2 + i) + (missing term) = 5(2 + i).
To find the missing term, we must first perform the multiplication of the complex numbers on the left side of the equation.
Multiplying (1 + 2i) by (2 + i) gives:
1 * 2 = 21 * i = i2i * 2 = 4i2i * i = 2i^2 (Since i^2 = -1, this term becomes -2)Add these results to get 2 + i + 4i - 2 = 5i, which simplifies to (0 + 5i). Now, we add the missing term to this, so we have:
(0 + 5i) + (missing term) = 5(2 + i)
Expanding the right side yields:
5 * 2 = 105 * i = 5iThis gives us (10 + 5i). Subtract (0 + 5i) from both sides to isolate the missing term:
(10 + 5i) - (0 + 5i) = missing term
Therefore, the missing term is 10, and the completed equation is (1 + 2i)(2 + i) + 10 = 5(2 + i).
Final answer:
The question involves finding the missing term in a complex number equation. After expanding and simplifying the complex multiplication, it's determined that the missing term is 10 to balance the equation.
Explanation:
The question is about expanding and simplifying a complex number equation and finding the missing term that makes the equation true. To find the missing term, we first need to expand the left side of the equation.
Step-by-Step Solution:
Multiply the complex numbers (1 + 2i)(2 + i).Simplify the product to get 2 + i + 4i + 2i2.Since i2 = -1, the expression simplifies to 2 + 5i - 2.Combine like terms to get 5i.To make the equation true, add the missing term to the left side. We have (1 + 2i)(2 + i) + missing term = 5(2 + i).The missing term must result in 5(2 + i).Since the product of the complex numbers is 5i, the missing term is 10 to get 5(2 + i).Final equation: (1 + 2i)(2 + i) + 10 = 5(2 + i).Therefore, the missing term in the equation is 10.

D. −5/12 ⋅ (6/5 ⋅ 1/3) ⋅ 9/2 = (−5/12 ⋅ 6/5) ⋅ (1/3 ⋅ 9/2)
The associative property of multiplication means that the way numbers are grouped within parentheses in an operation does not change the result. Looking at the options provided, option D represents this property. The other options represent other mathematical properties.
Explanation:The associative property in mathematics is a property of some binary operations, which means the way numbers are grouped within parentheses in an operation does not change the result. In multiplication, for example, this means that (ab)c = a(bc).
Looking at the options provided one at a time, we see that option D represents this property. The equation −5/12 ⋅ (6/5 ⋅ 1/3) ⋅ 9/2 = (−5/12 ⋅ 6/5) ⋅ (1/3 ⋅ 9/2) allows us to rearrange the numbers within parentheses without changing the product, just as the associative property dictates.
The other options represent other mathematical properties like the distributive property or the associative property of subtraction, not the associative property of multiplication.

A stadium has 50 comma 00050,000 seats. Seats sell for $3030 in Section A, $2424 in Section B, and $1818 in Section C. The number of seats in Section A equals the total number of seats in Sections B and C. Suppose the stadium takes in $1 comma 288 comma 8001,288,800 from each sold-out event. How many seats does each section hold?
A= B+C
As given, A+B+C = 50000 seats
A+(B+C) = 50000
2A = 50000
A= 25000 seats
Now section A sells seats at $30 each
So, [tex]25000\times30=750000[/tex]
Now, B+C = 25000
B = 25000-C
B sells at $24 and C sells at $18
So, 24B+18C = 538800
Now as section A incurs an amount of $750000 from booking, so B and C will incur 1288800-750000 = 538800 where $1288800 is the total booking amount.
24B+18C = 538800
[tex]24(25000-C)+18C=538800[/tex]
[tex]600000-24C+18C=538800[/tex]
6C = 61200
C = 10200
Now, B = 25000-C
B = 25000 - 10200 = 14800
Hence, section A has 25000 seats
Section B has 14800 seats
Section C has 10200 seats
each block in Ton’s neighborhood is 2/3 mile long if he walk 4 1/2 blocks how far does he walk?
if each block is 2/3 miles long, and he walks 4 1/2 blocks, we can simply multiply to two. It looks like this:
(2/3)(4 1/2)
to multiply, make 4 1/2 into an improper fraction and multiply normally
(2/3)(9/4)
Ton walks 3 miles total.
Final answer:
Ton walks a total distance of 3 miles if each block is 2/3 mile long and he walks 4 1/2 blocks by multiplying the length of one block by the number of blocks walked.
Explanation:
The question asks about the total distance Ton walks if each block in his neighborhood is 2/3 mile long and he walks 4 1/2 blocks. To find the total distance, we can multiply the length of one block by the number of blocks walked:
Convert 4 1/2 blocks to an improper fraction: 4 1/2 = 9/2 blocks.
Multiply the length of one block by the number of blocks: (2/3 mile/block) × (9/2 blocks) = (2×9) / (3×2) = 18 / 6 = 3 miles.
Therefore, Ton walks a total distance of 3 miles.

Find a polynomial function of degree 3 such that f (2) = 24 and x– 1, x and x+ 2
are factors of the polynomial.
f(x) = 3x³ + 3x² - 6x
given the factors of the polynomial , then
f(x) =ax(x - 1)(x + 2) ( a is a multiplier )
to find a use f(2) = 24
f(2) = 2a(1)(4) = 24 ⇒8a = 24 ⇒ a = 3, thus
f(x) = 3x(x² + x - 2) = 3x³ + 3x² - 6x
The polynomial function is [tex]f(x) = 3x^3 + 3x^2 - 6x[/tex].
Given that,
f(2) = 24.And, x– 1, x and x+ 2 represents the factors of the polynomial.Now based on the above information, the calculation is as follows:
f(x) =ax(x - 1)(x + 2)
Here a is a multiplier.
Now
f(2) = 24
f(2) = 2a(1)(4) = 24
8a = 24
a = 3
It can be write as
[tex]f(x) = 3x(x^2 + x - 2)[/tex]
[tex]f(x) = 3x^3 + 3x^2 - 6x[/tex].
Therefore we can conclude that the polynomial function is [tex]f(x) = 3x^3 + 3x^2 - 6x[/tex].
