Answer: C
Step-by-step explanation:
1+2e^x+1=9
2e^x+1=9-1
e^x+1= 8/2
e^x+1 = 4
Here we can applicate the Ln:
ln e^x+1 = ln 4
Applicating the log property for exponent:
(x+1).ln e = ln 4
Ln e = 1, so:
x+1 = ln 4
x = ln 4-1
Answer:
-11
Step-by-step explanation:
A, C, D are the correct answers.
-5 is neither a whole number nor a natural number. This is because negative numbers are not included in these. Hope this helps! Let me know:)
Factor the following:
x^2 - 16 x + 63
The factors of 63 that sum to -16 are -7 and -9. So, x^2 - 16 x + 63 = (x - 7) (x - 9):
Answer: (x - 7) (x - 9)
It’s 28 divided by 7 x 15 -13
How do I know ? I’m in high school and I just worked it out !!
