2y-4=3y-5
-4=y-5
1=y
Answer: y=1
Assuming ya mean

take derivitive
remember dy/dx e^x=e^x
also the chain rule
so

find where it equals 0


multiply both sides by e^x

divide both sides by 8

take ln of both sides


divide both sides by 9

x≈-1/5
f'(-1)<0
f'(0)>0
so it is increasing from x to infinity
the interval it is increasing on is
Answer: 120
42/x = 35/100
(42)(100) = 35(x)
4200 = 35x
120 = x
It is X=2 you have to see where it touched line
