4² - (x + 8)
x = 2
Step 2: Simplify
Evaluate exponents: 16 - (x + 8)Distribute negative: 16 - x - 8Combine like terms: 8 - xStep 3: Evaluate
Substitute in x: 8 - 2Subtract: 6Answer:
The Answer is A; 6
Step-by-step explanation:
If we use PEMDAS to solve the following question:
We solve for parentheses first.
(2+ 8) = 10
We then solve for the exponent
4^2 = 16
We then subtract
16 - 10 = 6

Students sold books to the local library as a part of a school drive. paper books were brought for $1.45 each. The library spent $98.60 on paper books . Hardback books were brought for $2.25 each. The library spent $328.10 buying used books. How many books did the library purchase?
Answers
Answer:
213 books
Step-by-step explanation:
Paper books = $1.45 each
$ 1.45 = 1 paper book
$ 1 = 1/1.45 paper book
$98.6 = 98.6/1.45 paper books
$ 98.6 = 68 paper books
Hardback books = $ 2.25 each
$2.25 = 1 Hardbook
$1 = 1/2.25 hardbook
$ 328.10 = 328.10/2.25 hardbooks
$ 328.10 = 145.822 hard books
Number of books cannot be a decimal number, so the value has to be estimated to a nearer whole number.
$ 328.10 = 145 hard books
Total number of books bought = (145 + 68)books= 213 books (Answer)

Ty is scuba diving. He is 15 feet below sea level. He descends 2.5 feet each minute. Which expression represents Ty’s location compared to sea level after 6 minutes?
A –2.5 + 6(–15)
B –2.5 – 6(–15)
C –15 + 6(–2.5)
D –15 – 6(–2.5)
Answers
Answer: The answer is c
Explanation: ty is already 15 feet below sea level. Every minute he descends 2.5 feet or (-2.5 feet). Now you multiply 6 and (-2.5) to get the depth that he would descends to in 6 min.
-15+6(-2.5)= -30 he would be 30 feet below sea level.
Answer:
C

Q- Write the nth term, generalized statement, and the 100th term of the given number sequence. (Need answer urgent!!....... WILL MARK AS BRAINLIEST!!)
1) 1,2,3......
2) 2,4,6.....
3) 3,5,7......
4) 1,4,7,10
5) -1,-2,-3
Answers
Answer:
1) n
2) 2n
3) 2n+1
4) 3n-2
5) -n
Step-by-step explanation:
To write a generalized statement for a pattern using n, we multiply n by the common difference between each term. We add the term number before the first term to this.
1) 1, 2, 3...
For the first question, the common difference is 1 because each term increases by 1. Multiply n by 1.
1n
To find the term number before the first term, we subtract 1 from the first term.
1-1=0
Therefore, our general statement is 1n+0, or just n.
2) 2, 4, 6...
The common difference is 2 because we add 2 each time. Multiply n by 2.
2n
The term number before the first term is equal to the first term - the common difference.
2-2=0
Therefore, our general statement is 2n+0, or just 2n.
3) 3, 5, 7...
The common difference is 2 because we add 2 each time. Multiply n by 2.
2n
The term number before the first term is equal to the first term - the common difference.
3-2=1
Therefore, our general statement is 2n+1.
4) 1, 4, 7, 10...
The common difference is 3 because we add 3 each time. Multiply n by 3.
3n
The term number before the first term is equal to the first term - the common difference.
1-3=-2
Therefore, our general statement is 3n+(-2), or 3n-2.
5) -1, -2, -3...
The common difference is -1 because we subtract 1 each time. Multiply n by -1.
-1n
The term number before the first term is equal to the first term - the common difference.
-1-(-1)
= -1+1 (because two negatives make a positive)
= 0
Therefore, our general statement is -1n+0, or just -n.

Answer:
[tex]y=-4x+2[/tex]
Step-by-step explanation:
To do this you would set up the equation for finding slope which is [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex] and you would plug the numbers in. First you would subtract -6 and -2 which is -4 and you would subtract 2 and 1 which is 1. Than you get -4/1 which is -4. To check you would do that same thing with the next set of numbers and get -4 so you know what the m is now. To solve for the b you can see that there is a pattern with the numbers, the x goes up 1 and the y goes down 4 so that means you would just do the opposite of that to get b so for b you would get (0,2). Your final answer would be y=-4x+2
