Step-by-step explanation:
got it right on ed
There are 336 different ways are there to present those ribbons if the order matters.
What is the combination?A combination is a mathematical technique that determines the number of possible arrangements in a collection of items where the order of the selection does not matter.
Eight students are competing for a blue, red, and yellow ribbon for their agriculture project.
Different ways are there to present those ribbons if the order matters.
By permutations, we have to calculate the number of different ways to arrange the ribbon is;
[tex]=3 \times 2\times 1\\\\=6[/tex]
Now, we have to calculate the different ways to choose 3 winners from 8 is;
[tex]=8\times 7\times 6\\\\=336[/tex]
Therefore, the correct option is (b), 336 ways are there to present those ribbons if the order matters.

(1a) There is a closed carton of eggs in Mai's refrigerator. The carton contains e eggs and it can hold 12 eggs. What does the inequality e<12 mean in this context?
Answer:
e<12 mean in this context means that the number of eggs in the carton is not up to 12
Step-by-step explanation:
The number of eggs in the carton = 12
The capacity of egg carton is depicted as e
Hence, the inequality e<12 in this context means that :
The number of eggs in the carton is less than the capacity of the egg carton
Thus we can conclude that the number of eggs in the carton is not up to 12, which is the number of eggs the carton can hold.

Answer:
3) [tex]qm^{-17}[/tex]
4) [tex]np^{-3}[/tex]
These should be your answer! Make sure to double check!
Step-by-step explanation:
Just simplify.
A- {(-4, -3), (2, 2), (2, 1), (0, 3), (-2, 4}
B- {(-3, -4), (2, -2), (2, 1), (3, 0), (4, -2)}
C- {(-3, -4), (-2, 2), (2, 1), (3, 0), (4, -2)}
D- {(-3, 4), (-2, -2), (1, 2), (3, 0), (4, 2)}
Answer:
C
Step-by-step explanation:
The first point would be (-3,-4) which means A and D are eliminated.
The second point is (-2,2) which means you are left with C which is the correct answer

D
Step-by-step explanation:let's rewrite this
x + y = 11 - equation 1
- x = - y - 9 - equation 2
solve the first equation for x
x + y = 11 (add -y to both sides to get x by itself)
x = -y + 11 - equation 3
now substitute -y + 11 for x in the second equation
y - 11 = - y - 9 (2 negative signs next to each other equals positive)
2y - 11 = -9 (add y to both sides)
2y = 2 (add 11 to both sides)
y = 1 (divide both sides by 2)
now substitute y = 1 into equation 3
x = -1 + 11
x = 10
therefore, x = 10 and y = 1. in coordinates, x goes before y
therefore, the coordinates are (10, 1)
therefore the answer is D
good luck my friend! hope this helped a lot! also, i found a website if you don't fully understand this, its called MathPapa, i didn't use it to work this out so my working might be different but it definitely helps me sometimes. for an equation like this, type it likes this: x+y=11; -x=-y-9

Answer:
C
Step-by-step explanation:
In order to find "b" (the y-intercept) from the equation y=mx+b ... If you know the slope (m), use any one of the given points by substituting the Y value of the given point for y, and substituting the X value of the given point for x. Solve for b = Y-mX.

What is the value of in the solution of the
system of equations 3x + 2y = 12 and 5x – 2y = 4?
Answer:
x = 2
y = 3
Step-by-step explanation:
add the 2 together and the y-values drop out and you are left with:
8x = 16
x = 2
3(2) + 2y = 12
2y = 6
y = 3
Nalani says the expression 9+7r cannot be factored using the GCF. Is she correct? Explain why or why not
Answer:
Nalani is correct.
Step-by-step explanation:
Given - Nalani says the expression 9+7r cannot be factored using the GCF.
To find - Is she correct? Explain why or why not.
Proof -
GCF - Greater Common factor
Given that, the expression is - 9 + 7r
As
HCF(9, 7) = 1
So , we can not factor the expression.
i.e. there does not exist any number who is a multiple of 9 and 7 both.
So,
Nalani is correct.
Example -
Let the expression be 24 + 18x
HCF(24, 18) = 6
So,
24 + 18x = 6(4 + 3x)
