Answer:
Answer choice C) 3a-3
Step-by-step explanation:
Your perimeter is of (10a-6). The first step would be multiply 2a by 2 since you have to sides. Which would give you to 4a. Next you will have to subtract 4a from (10a-6). This would give you 6a-6. Finally divide by two and you will get 3a-3.
Rolling an even number would be 1/2 possibility while flipping tails would be 1/2 possibility hence the answer is 1/4
It would be 0.4:) hope this helps
Minimum is (5,0)
There is no maximum so maximum is N/A
Where the function is increasing is x>5
Function decreases where x<5
Just substitute it into the gradient formula which is: y2 - y1 / x2 - x1. So 2-3/2-9 = -1/-7 = 1/7
