Evaluate f(x)=8(2)^x x=-3

Mathematics
1 answer:
skad [1K]3 years ago
7 0
Plug in -3 for x

f(-3) = 8(2^-3)

2^-3 = 1/2^3 = 1/6

f(-3) = 8(1/6)

f(-3) = 8/6

Simplify. Divide 2 from both numerator and denominator

f(-3) = (8/6)/(2/2)
f(-3) = 4/3

f(-3) = 4/3 , or 1 1/3

hope this helps

If the price of a purse increased from $45 to $54, what was the percent of increase
Marrrta [24]
If you set it up in cross multiplication then you would have (x/100 = 45/54) then cross multiply so then i would look like this (54x/4,500) so from there you would divide 54 from 4,500 i hope this helps in any way  oh and it should come up to be 83.3333333 which would be 83% lol
