Cecil is replacing lightbulbs in the office where he works. when he started, he had x boxes of lightbulbs with 2 bulbs in each box. after replacing 16 lightbulbs, he has at least 12 bulbs left. which inequality represents the number of boxes of lightbulbs cecil started with? how many boxes of lightbulbs is that? the inequality represents the number of boxes of lightbulbs that cecil started with. cecil had boxes of lightbulbs when he started.

step-by-step explanation:

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
