Determine whether each x-value is a solution (or an approximate solution) of the equation.
log4(3x)=3
a. x≈21.333
b. x=-4
c. x=64/3

Log4(3x) = 3
is the same as:

4³ = 3x
64 = 3x
64 / 3 = 3x / x
x = 64 / 3

x ≈ 21.333

Therefore, c is an exact solution, and a is an approximate solution (not showing all the repeating digits, so it's not exact).
Hope this helps! :)

The answer is 270 cars.you can do this by making a proportional relationship. for instance, 200 is the whole we are using, so on a “number line” 200 would be over 100%. now, since he sells 35% more, add 35% to 100% to get 135% on the other side of the “number line” on the bottom half, leaving the top half empty.cross multiply 200 by 135 then divide by 100 to get your answer. i hope this , if it did, , if you don’t mind, giving me brainiest! 200/100% } 200 • 135 /100 ? /135%
