Joe filled up his car with gas before embarking on a road trip across the country. The capacity of Joe’s gas tank is 12 gallons, and after driving for four hours, there were 4 gallons of gas left in the tank. Write an equation for G, in terms of T, representing the number of gallons of gas remaining in Joe’s gas tank after T hours of driving. G=

G=-2t+12

It’s this because I was doing it and got it wrong so it gave me the answer. Sorry just need some to write here

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

you save $70

discount would be 35% off
