Log(7x+1) - log(x-2) =1
log[(7x+1) / (x-2)] =1 or log[(7x+1) / (x-2)] =log10 (log10=1)
it means (7x+1) / (x-2) =10
Solving ===> x=7
Answer: 11
Step-by-step explanation:The given expression is:
=
=
=
Substituting the value of b=-2 in above expression, we get
=
=
=
Thus, the value of the given expression is -11.
Lets solve the equation and see the steps so it is easier.
x/2 - 8 = 14
Add eight to both sides of the equation to get x/2 alone.
x/2 - 8 + 8 = 14 + 8
x/2 = 22
Multiply both sides by two to get x alone.
x/2 • 2 = 22 • 2
x = 44
Now we see the steps we made. Lets look at the choices. Your answer is the third choice. I hope this helps!
Answer:
4 kilometers north
Step-by-step explanation:
2 kilometers north up 2
2 kilometers east, right 2
2 kilometers west then left 2
We are now at the position of up 2 again
6 kilometers south down 6
up 2 down 6 leaves us at down 4
We are 4 km south
We will need to go 4 km north to get back to the dock
Answer:
192
Step-by-step explanation:
Well if the first rectangle is 72 and 56, then we can find the area of that by multiplying length times width which would be 4032, so that would be the area of the second one. then we divide 4032 by 21, which is 192.
P.S, This is my first question answered, so if im wrong please let me know, thank you!
