Answer:
4
Step-by-step explanation:
Irrational number are real numbers that do not end and cannot be written as a fraction.
4.66666...
can also be written as 4 2/3 therefore it is rational because it can be written as a fraction.
It is not a terminating decimal because it doesn't end(repeating).
Answer:3130/3
Step-by-step explanation:
11 times with a remainder of 5
Answer:
6 and -8
Step-by-step explanation:
Solve:
xy = 48
x + y = -2
You can say y = -2-x = -(x+2) and then substitute that in the first:
-x(x+2) = 48
-x² -2x - 48 = 0
x² + 2x + 48 = 0
Quadratic formula can do the rest if you don't "see" the factorization.
Answer:
x > -2, or (-2, infinity)
Step-by-step explanation:
Alexis, all inputs to the natural log function y = ln x must be greater than zero.
Looking at the given y = ln (x + 2), we see that (x + 2) must be greater than zero for the reason given above.
Thus, the domain of y = ln (x + 2) is x + 2 > 0, or (by subtracting 2 from both sides) x > -2, or (-2, infinity)
