Y=-1.5+9=7.5
2x+2x7.5=16
2x+15=16
2x=16-15
2x=1

4vir4ik [10]

Given :

A holiday meal cost 12.50 a person plus a delivery fee of $30 at we cater.

The same meal cost $15 a person with no fee at Good Eats.

To Find :

When does we cater become the better deal.

Solution :

Let , x is number of order .

Cost at cater , C = 12.5x + 30 .

Cost at Good Eats , G = 15x .

We need to find :

G > C

15x>12.5x + 30\\\\2.5x>30\\\\x>12

Therefore, after 12th order cater will be more value for money.

Hence, this is the required solution.

E^(8x)+e^(-x) find the interval on which f is increasing
saveliy_v [14]
Assuming ya mean
f(x)=e^{8x}+e^{-x}
take derivitive
remember dy/dx e^x=e^x
also the chain rule

so
f'(x)=8e^{8x}+-1e^{-x}
find where it equals 0
0=8e^{8x}+-e^{-x}
e^{-x}=8e^{8x}
multiply both sides by e^x
1=8e^{9x}
divide both sides by 8
\frac{1}{8}=e^{9x}
take ln of both sides
ln(\frac{1}{8})=ln(e^{9x})
ln(\frac{1}{8})=9x
divide both sides by 9
\frac{ln(\frac{1}{8})}{9}=x

x≈-1/5
f'(-1)<0
f'(0)>0

so it is increasing from x to infinity

the interval it is increasing on is (\frac{ln(\frac{1}{8})}{9},  \infty)
