Y + R + V = 42
but 4 YEARS AGO : (R-4) +(V-4) = Y

Replace Y in the 1st equation by:  (R-4) +(V-4)

(R-4) +(V-4) + R + V = 42

2R - 2V - 8 = 42;  2R -2V  = 50, or R+V=25
IF R+V =25 AND Y + R +V = 42, then Y + 25 = 42 and Y =17

What logarithmic function represents the data in the table?.
baherus [9]
<span>  x   | f(x)
 25  |  2
125 |  3 
625 |  4

From my research, the above table belongs to the question. The values in x show increasing exponential values of 5, where:

5^2 = 25
5^3 = 125
5^4 = 625

As for the case of f(x), they are the values of the powers. So the logarithmic function that would explain the values of x and f(x) would be:

A base-5 function:

How to solve 6=x+2/3
Dafna11 [192]
6 = x + 2/3

We're simply just trying to get "x" isolated.

So, we must subtract 2/3 from both sides.

6 - 2/3 = x 

Simplify.

Turn 6 into an improper fraction.

6 is now 18/3 :)

So, our new problem looks like this :

18/3 - 2/3 = x

Simplify.

16/3 = x

Turn 16/3 into a mixed fraction.

How many times does 3 go into 16? 5 times! :)

So, we do this :

3 × 5 = 15

16 - 15 = 1

So, x = 5 1/3
