Remember that you cannot take the log of a negative number, regardless of the base. Also, you can take the logarithm of zero, since no number raised to a power can equal zero (although it come very close).
Therefore, (x+3), the number inside the logarithm, must be greater than zero.
x+3 > 0
x > -3
The domain is x > -3,
or (-3, ∞) in interval notation
5x+2=47 subtract 2 from both sides
5x=45 divide both sides by 5
x=9

252
Step-by-step explanation:
7/25=252/900
Answer:
-3
Step-by-step explanation:
(3x + 10)98°
294x+980
294x=-980
X=-980/294
X=-3
So the value of X is -3
