The number of messages posted each day on an online message board during the first 5 days it was open are listed below
2,350 2,900 3,450 4,000 4,550
The number of messages posted each day follows a pattern. Which expression can be used to determine the number of messages
posted on the nth day?
O A. 2,350n
ов.
550(n + 1,800)
O C.
550n + 1,800
O D.
1,800n + 550
= C, 550n + 1800
Here is how you make a expression for a sequence:
1) Firstly, identify the number gap. This is 550. 2350 + 550 = 2900. 2900 + 550 = 3450, ect. So this means that it is 550n.
2) n is basically just the number in the sequence it stands on. n for 2350 is 1. So now you need to know what you must add to 550n to get whatever n is. We will choose 2350. n is 1 for it. 550 x 1 = 550. 2350 - 550 = 1800. So it is 550n + 1800.

What are the coordinates of the point (-3, 0) after a translation 2 units up?
A. (-3,2)
B. (-5,0)
C. (-3,-2)
D. (-1,0)
Answer: (-3,2)
Step-by-step explanation:
It's a translation 2 units UP, which means vertically, which means the Y Axis, so your (-3,0) which is formatted like: (x,y) would add 2 to the y variable of the coordinate -> (-3,2), You don't even need a graph for this problem tbh.
The coordinates of the (-3, 0) after a translation 2 units up is: A. (-3, 2).
What is Translation?Translation is a form of transformation, whereby the points of a figure is moved from one position to another by the same distance in a given direction.
Given a point, (-3, 0), after translation 2 units up, that is, 2 units up along the vertical axis (y-axis), we would have:
(-3, 0 + 2 units) = (-3, 2).
Thus, the coordinates of the (-3, 0) after a translation 2 units up is: A. (-3, 2).

Solve (-7/3)x -3=-53
Answer: 21
Step-by-step explanation:
Add 3 to both sides so then it would be -7/3x=-49
Then multiply the reciprocal of -7/3 which is -3/7 to both sides
It would then be x=-49 times -3/7 and if you simplify that it becomes 21

Further Explanation:
Whenever you are doing a proof, always start with the given info. It may seem silly to literally repeat (word-for-word) what your teacher has given you, but this is how all proofs start out. It helps place an anchor point in which you can connect to what you want to prove.
So this is why the first line is literally a repeat of what your teacher has stated. The reason you'll state is "given".
------------------
For reason 2, we use the vertical angle theorem. Vertical angles are always congruent.
Vertical angles form whenever we have an X shape like this of two segments crossing. The angles are opposite one another (almost like mirror images of sorts).
-----------------
Lastly, reason 3 uses the SAS (side angle side) similarity theorem.
This is the theorem which says that if you have two pairs of sides in proportion and a pair of congruent angles between those sides, then we can prove the triangles similar.
Statement 1 handles the sides being in proportion. Statement 2 handles the congruent angles.
As you can see, everything in this proof builds step by step toward the final goal of saying triangle ABC is similar to triangle EBD.

Which sequence is geometric and which is arithmetic?
Answer:
See below
Step-by-step explanation:
Geometric sequences have a common ratio while arithmetic sequences have a common difference.
On the left table, we can see that it's an arithmetic sequence because 3+2=5, 5+2=7, and so on.
On the right table, we can see that it's a geometric sequence because 3*2=6, 6*2=12, and so on.
Basically, if you see a multiplication pattern for the output, it's a geometric sequence. If you see an addition (or subtraction) pattern for the output, it's an arithmetic sequence

Arun bought a pair of skates at the sale where the discount given was 20%. If the amount he pays is 1600 find the marked price
Answer:
2000
Step-by-step explanation:
1600 is 100% - 20% = 80% of the original price.
So it is 4/5 of the original price.
So, the marked price is 1600 * 5/4 = 2000

One species of fish in a fishery had an initial population of 255 fish and grew by 25 fish each season. A second species that was being overfished started with an initial population of 450 fish, and then decreased by 40 fish each season. Assuming a linear change, write equations for the populations of each species. When will the two populations have the same amount of fish? After how many seasons will the second species be eliminated?
Answer:
they intersect at 3.5 seasons, 312 fish. the second gets elimed at 11 seasons
Step-by-step explanation:
equations:
first:
amount of fish = 225 + 25*season
second:
amount of fish = 450 - 40*season

Answer:
The answer is B = 113.4 = x (18)
x = 6.3
Step-by-step explanation:
A product of a number, x, and 18 is 113.4.
This means x*18=113.4
Now we solve:
x(18) = 113.4, Also can be written as 113.4 = x(18)
18x = 113.4
/18 /18
x = 6.3

A bag contains 7 green marbles,2 white marble s, 5 orange marbles,9 blue marbles, and 7 red marbles. a marble will be drawn from the bag and replaced 180 times what is a reasonable prediction for the number of times a white or red marble will be drawn?
The reasonable probability that a white or red marble will be drawn all 180 times is; (3/10)¹⁸⁰.
Probability with replacementSince the probability is with replacement;
First, the total number of marbles in the bag is; 7+2+9+5+7 = 30.Hence, the probability that a white or red ball is drawn each time is; 2+7 = 9 possible outcomes.
Hence, it follows that the probability for white or red each time is; 9/30 = 3/10
Hence, when drawn 180 times, the probability is;
P = (3/10)¹⁸⁰.Read more on probability;
