The first one is
5x-15=2x+12+3x
5x-2x-3x=12+15
0=27
The second one is
6.5x-7.75x=-12+14.5
-1.25x=-2.5
Divide both sides by - 1.25
X=. 02
The third one is
K-10=3
K=13
The second part of the third one is
-|k-10|=3
-k+10=3
-k=3+10
-k=13
Divide both sides by negative
K=-13
The fourth one is
4n+32=56
4n=56-32
4n=24
Divide both sides by 4
N=6
The second part to that one is
-4|n+8|=56
-4n-32=56
-4n=88
Divide both sides by - 4
N=22
The fifth one is
N+7-6=8
N=8-7+6
N=1+6
N=7
The second part to this one is
-|n+7|-6=8
-n-7-6=8
-n=8+7+6
-n=21
Divide both sides by negative
N=-21
The last one is
5x-7-3=9
5x=9+7+3
5x=19
Divide both sides by 5
X=19 over 5
The second part to this one is
-|5x-7|-3=9
-5x+7-3=9
-5x=9-7+3
-5x=5
Divide both sides by - 5
X=-1
I hope this helps you out.
Answer:
Step-by-step explanation:
The answer is D, the function approaches 1 as x approaches +- infinity. We can divide each term by x^2. We will get the following:

as x goes to infinity, the -4/x^2 and -9/x^2 go to 0. To the equation just becomes 1/1. So the answer is 1.

NOREAL SOLUTION
Step-by-step explanation:
6x2+125=x2
Step 1: Subtract x^2 from both sides.
6x2+125−x2=x2−x2
5x2+125=0
Step 2: Subtract 125 from both sides.
5x2+125−125=0−125
5x2=−125
Step 3: Divide both sides by 5.
Step 4: Take square root.

Hello :
f(x) = 3 /(x+2) - <span>√(x-3)
f(7 ) = 3/(7+2) - </span>√(7-3)
f(7) = 1/3 - √2 = 0.33 - 1.41 = - 1.1
