Answer:
$105
Step-by-step explanation:
Since x=8/3 is a vertical line,the slope is undefined,
F(0)= 2* 0 +3
=0+3
f(0)=3
Answer:
6
Step-by-step explanation: You can set up the equation: 
= 
You square both sides to cancel out the squares which leaves you with 
= n - 4. Then you just solve as normal which ends you up with an answer of 6. You can check this by plugging 6 back into the equation and see that you end up with 
on both sides.
