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
950 - 188 = 762

Answer:
The answer is C
Step-by-step explanation:
Let X and Y be two proportional quantities and let K be constant.
Y=KX so Y/X=K
So for Equation number 1 we have 4y=3x and we will fill it in for 4/3=K
solving to get 1.33...
Now repeat this for the rest to complete the chart
1- 1.33...
2. 1.6
3- 1.33...
4- 0.625
Now we can see that 1 and 3 are the same, so that's how you get your answer, hope this helps!
