Does this model represent a compound? Explain your
answer
Answers
Answer:
No
Step-by-step explanation:
The model shows two similar elements.
Although we do not know what the element is, we can conclude that the model is not a compound.
This is because the definition of a compound is when two different elements join.
However, the model has two similar elements, which forms a molecule, not a compound.
Answer:
The model does not represent a compound because it shows two atoms of the same element combined.
Compounds are made of two or more atoms of different elements.
In a ball-and-stick model of a compound, there should be balls of different colors

Answer:
Simplified radical form is
Step-by-step explanation:
In this problem we have the sum of two radical expressions. First step is to rewrite the radical using factorization process. Numbers 54 and 24 can be written as the products of square and non-square numbers.
After that, we can replace the numbers in the radical expression, and we can simplify them. Square numbers can be simplified with the radical. Then, we can expand the products.
Now, we can take the radical as common term and add the numbers.
Finally, Simplified radical form is
The simplified radical form of 2√54 + 5√24 is 16√6.
How to find the simplified radical form
To simplify the expression 2√54 + 5√24, we can first simplify the square roots of the numbers under the radicals.
√54 can be simplified as follows:
√54 = √(9 * 6) = √9 * √6 = 3√6.
Similarly, √24 can be simplified as:
√24 = √(4 * 6) = √4 * √6 = 2√6.
Now, we can substitute these simplified forms back into the original expression:
2√54 + 5√24 = 2(3√6) + 5(2√6).
Applying the distributive property, we have:
2(3√6) + 5(2√6) = 6√6 + 10√6.
Combining like terms, we get:
6√6 + 10√6 = (6 + 10)√6 = 16√6.
Therefore, the simplified radical form of 2√54 + 5√24 is 16√6.

Switch the x- and y-coordinates
Step-by-step explanation:
-8x-5y=-11
Can u help me on this
Answers
-8x-5y=-11 (2)
sub 1 into 2
-8x-5(4x+19)=-11
-8x-20x-95=-11
-28x-95=-11
-28x=84
x=84/-28
x= -3
sub into 1
y=4(-3)+19
y=7
therefore x= -3 and y=7
Steps:
1. Substitute the y in -8x-5y=-11 for 4x + 19
-8x-5(4x + 19)= -11
-8x + (-20x) + (-95)= -11
-28x + (-95)=-11
2. Now add 95 on both sides
-28x= 84
3. Divide by 28 on both sides
4. X=-3
5. Now substitute the x in y= 4x + 19 for -3
Y= 4(-3) + 19
Y= -12 + 19
Y= 7
6. Your answer is x = 3 and y= 7 or (3,7)

The inequality is 23-s≥5 so, option A is correct.
What is inequality?
Inequality is the relationship between two expressions such that those expressions are not equal.
A person spend $s on the food. Determine the amount left for the dessert.
23-s
The amount left should be greater than or equal to $5 so that a person can purchase dessert.
23-s≥5
Thus, the inequality represents the given situation is 23-s≥5.
