Which system of equation can represent the equation?

Q:
Which system of equation can represent the equation?
Accepted Solution
A:
Answer:
log(x+3)
y₁ = --------------
log(4)
log(2 + x)
y₂ = ----------------
log(2)
Explanation:
1) Here you must use the property named change of base of the logarithm.
That rule is:
[tex]log_{a}b= \frac{log_c{b}}{log_ca} [/tex]
2) Changing to base 10 that is:
[tex]log_{b}a= \frac{loga}{logb} [/tex]
3) Using it with the given equation, you get:
[tex]log_4(x+3)= \frac{log_(x+3)}{log(4)} log_2(2+x)= \frac{log(2+x)}{log(2)}[/tex]
4) Now, to set your system you can make the left side of the equation equal to y₁ and the right side equal to y₂
log(x+3)
y₁ = -------------
log(4)
log(2 + x)
y₂ = ---------------
log(2)
And that is your system which is the first choice of the list.
