Answer:
x=8
Step-by-step explanation:
(2x + 1)² = x² + (2x - 1)² = x² + (2x - 1)(2x - 1)
(2x + 1)(2x + 1) = x² + 4x²-2x-2x+1
4x²+2x+2x+1 = 5x²-4x+1
4x²+4x+1 = 5x²-4x+1
0= 5x²-4x²-4x-4x+1-1
0= x²-8x
x²-8x=0
x²=8x
x=8
The Bald Eagle is an endangered species making a remarkable comeback. Its population has grown 6% annually since 1975, when there were only 575 nesting pairs in the continental USA. a) Is this situation linear or exponential? Why?

Find the 75th term of the arithmetic sequence -17, -13, -9....
Answer:
The 75th term of the arithmetic sequence -17, -13, -9.... is:
[tex]a_{75}=279[/tex]
Step-by-step explanation:
Given the sequence
[tex]-17, -13, -9....[/tex]
An arithmetic sequence has a constant difference 'd' and is defined by
[tex]a_n=a_1+\left(n-1\right)d[/tex]
computing the differences of all the adjacent terms
[tex]-13-\left(-17\right)=4,\:\quad \:-9-\left(-13\right)=4[/tex]
The difference between all the adjacent terms is the same and equal to
[tex]d=4[/tex]
The first element of the sequence is:
[tex]a_1=-17[/tex]
now substitute [tex]d=4[/tex] and [tex]a_1=-17[/tex] in the nth term of the sequence
[tex]a_n=a_1+\left(n-1\right)d[/tex]
[tex]a_n=4\left(n-1\right)-17[/tex]
[tex]a_n=4n-21[/tex]
Now, substitute n = 75 in the [tex]a_n=4n-21[/tex] sequence to determine the 75th sequence
[tex]a_n=4n-21[/tex]
[tex]a_{75}=4\left(75\right)-21[/tex]
[tex]a_{75}=300-21[/tex]
[tex]a_{75}=279[/tex]
Therefore, the 75th term of the arithmetic sequence -17, -13, -9.... is:
[tex]a_{75}=279[/tex]

translation 4 units up
translation 1 unit up
translation 1 unit down
translation 4 units down
Answer:
translation 4 unites up
Step-by-step explanation:
the thing that is changing is the y intercept and the y intercept went up by 4 therefore it is a translation 4 units up
hope this helps (:
The transformation from the function g(x)=x²-5 to h(x)=x²-1 is translation 4 units up. Therefore, option A is the correct answer.
What is a transformation?A transformation is a general term for four specific ways to manipulate the shape and/or position of a point, a line, or geometric figure. The original shape of the object is called the Pre-Image and the final shape and position of the object is the Image under the transformation.
The given functions are g(x)=x²-5 and h(x)=x²-1.
From the function g(x)=x²-5 to h(x)=x²-1, the translation by 4 units up.
Now, g(x)=x²-5+4
So, h(x)=x²-1
Therefore, option A is the correct answer.

solve for t. -1 (t + 8) = -7.1 brainly
t=___?
(Please hurry!)
Answer:
.9
Step-by-step explanation:
-1(t+8) = -7.1
PEMDAS
So times the parenthesis by -1
-t - 8 = -7.1
Add the 8 to itself to get rid of it
Then since you added it on the left, add it to the right
-t = .9
t = .9

Find an order pair (x,y) that is solution to the equation 3x-y=8
Answer:
(2.67,-8)
Step-by-step explanation:
You first make x 0 so it is -3x0 to cancel that out to find y. You then see that you get -y=8 so you make y positive by moving the negative to the other side to get y = -8. Then, you do the same type of process for x and get 2.67. I could be wrong but wanted help as much as I could!
