The correct answer is A) a translation 2 units right and 4 units down.
Both of the reflections listed would keep the digits but change their signs and/or placement.
A translation 2 units right subtracts 2 from the x-coordinate. A translation 4 units down subtracts 4 from the y-coordinate. Comparing each pre-image point to its image, we can see that is what happened.
<h2>(☞^o^) ☞</h2><h2>Here's your answer </h2>
Step-by-step explanation:
Let the two consecutive natural numbers be x and x+1
Now, according to the problem
x+(x+1)=23
⇒ 2x+1=23
⇒ 2x=23−1
⇒ 2x=22
⇒ x=22÷2=11
The one number is 11
The next number is x+1=11+1=12
Hence the numbers are 11 and 12.

Answer: 1,953,125
This is one single value and it is just a bit under 2 million.
Or more accurately, it's a bit over 1.9 million.
===========================================================
Explanation:
- a = 5 = first term
- r = -5 = common ratio
Note that dividing any term by its previous term gets us the common ratio
- r = term2/term1 = -25/5 = -5
- r = term3/term2 = 125/(-5) = -5
The r value must stay the same the entire time, or else the sequence isn't geometric.
The nth term of any geometric sequence is a*(r)^(n-1). With the 'a' and 'r' values we found, we update that to 5(-5)^(n-1)
-----------------
To verify that is the correct nth term expression, plug in various values of n to compare it with the given sequence.
If we tried n = 2 for instance, then we find the 2nd term is
5(-5)^(n-1) = 5(-5)^(2-1) = -25
which matches what your teacher gave you. I'll let you verify the other terms.
-----------------
The last thing we need to do is plug in n = 9 and simplify
5(-5)^(n-1)
5(-5)^(9-1)
5(-5)^8
5(390625)
1,953,125 this is one single value (rather than 3 separate values)
Option 3 is the correct one
Answer:
Theyre both going to be 27.
Step-by-step explanation:
2n+21=4n+15
-2n -2n
21=2n+15
-15 -15
=
3=n
2n+21
2(3)+21=27
4n+15
4(3)+15=27
