Solve the equation log4(x + 20) = 3
salantis [7]

Answer:

Step-by-step explanation:

I don not understand what is for 4 here. So there are 2 cases:

Case 1: If you mean: log[4(x+20)]= 3

We know 3 = log(10^3)= log(1000)

So we have log[4(x+20)]= log(1000)

so 4(x+20)= 1000

and x+20 = 1000/4

x+20 = 250 and finally x= 250-20, x=230

The solution is 230.

Case 2; If you mean that 4 is the base of logarithm.

log_{4}(x+20)= 3

and we know that 3=log_{4}(3^{4} )= log_{4}(81)

So we have log_{4}(x+20)= log_{4}(81)

and x+20 = 81

or x= 81-20

x=61

The answer is 61.

Hope that useful for you, both cases.

The value of a collectible coin can be represented by the equation y=2x+9.74, where x represents the number of years that Consue
enyata [817]
Y = 2x + 9.74
x = number of years owned
y = total value in dollars

y = 2(0) + 9.74
y = 9.74
Substitute x with 0 because the question asks what is the value of coin when consuelo originally purchased it. So, at the time of purchase it's been 0 years since he owned it.
