The anwser of your problem is 2536 do you need an explanation
5x - 5 = x + 11
5x = x + 16
4x = 16
x = 4
The answer is 1. Anything to the 0 power is 1.
Answer:
$60
Step-by-step explanation:
set up a proportion and cross-multiply:
3000/400 = cost/450
c = cost
3,000c = 180,000
c = 180/3
c = 60
E^2x - 5e^x = 24
(e^x)^2 - 5e^x =24
let e^x = u
u^2 - 5u = 24
u^2 -5u - 24 =0
(u - 8)(u+3)=0
u = 8 or u = -3
since e^x = u then u can't equal -3
e^x = 8
by taking ln for both sides
ln(e^x) = ln(8)
xln(e) = ln(8) .......................ln(e) = 1
x = ln(8) = 3ln(2)
