Answer: A and B have exactly one solution.
A)x=-1
B)x=1
C)x=8 1/12
D)x=-97/206
Step-by-step explanation:
As you know, the domain is the values "x" can safely take on.
well, for a logarithmic expression, it can never have an expression of 0, namely in this case, x + 4 must never be 0, since such a logarithm doesn't exist.
now, x + 4 = 0 ---> x = -4.
thus if "x" ever becomes -4, we'd end up with log₃(-4+4), or log₃(0), which is a no dice.
so the domain is all values except -4.
Answer:
Look at the below screenshots that i hope helps :D :
First, distribute to simplify the equation.
-3*w = -3w
-3*4 = -12
-3w + (-12) = -18
Now, isolate the variable.
-3w + -12 = -18
+12 +12
- 18 + 12 --> -6
-3w = -6
-3w/-3 = -6/-3 >>>>> w = 2
Answer: w = 2
Answer:
x = –4
Step-by-step explanation:
x = –koef x / (2•koef x²)
