Answer:
x=-20
Step-by-step explanation:
x+9=-11
Subtract 9 from both sides. (-11-9=-20)
x=-20
The solution to the problem is as follows:
If you use Ln you can get rid of e.
ln(e^0.4x) = ln(0.4)
0.4x = ln(0.4)
x = (ln(0.4))/0.4
<span>x = -2.29

3000x + 1000y < 30000
2000x + 6000y < 30000
x = 7.5
y = 7.5
