The value of a computer decreases with its age, until it is worth nothing. A computer that was purchased new (age 0 years) for $2200 is worth $1540 after 6 years.
The linear function V(x) that expresses the value of the computer as a function of the age (x) in years is V(x)=

years the computer will be worth nothing.

for the points

step-by-step explanation:

question:

could we have options?

x =-.20752

step-by-step explanation:

4^(x+2)=12

4^(x+2)=12

take the log base 4 on each side

log 4 (4^(x+2) = log 4(12)

we know log b(a^y) = y log b (a)

(x+2) log 4(4) = log 4 (12)

x+2 = log 4 (12)

we know   logb c = loga c/loga b

we want to convert to base 10   so a = 10

by default, we do not write the 10   c = 4   and b = 10

log4 10 = log 12/log 4

log4 10 = log 12/ log 4

x+2 = log 12/ log 4

subtract 2 from each side

x +2 -2 = log 12/ log 4 -2

x = 1.79248125 -2

x =-.20752

2 2/3 hours duhh silly
