Solve for x: log5(3×-1)=2

1 answer:

6 0

If 5 is the base, 3(x-1) is the argument:
3x-1=5²
3x=26
x=26/3

If 5 is with 3x-1, that is, if 5(3x-1) is the argument, and the base is 10:
5(3x-1)=10²
3x-1=20
3x=21
x=7

Answer:

The range of the set of ordered pairs are $Y =\{-1,-7,-11,-15\}$ .

Step-by-step explanation:

Let $(x,y)$ be an ordered pair, where $x$ corresponds to an element of the domain and $y$ , an element of the range. Hence, the range of the set of ordered pair are:
