Answer:
circumference
Step-by-step explanation:
Answer:
about two feet
Step-by-step explanation:
So there are two ways.
First you could solve for y and plug it into the calculator. one equation for y1 and another for y2. Then go 2nd trace and press 5 and then press enter 3 times to find the intersection.
the second way is to solve by hand. I would suggest solve the first equation for y and plug the equation solved for y into the other equation. so y = -3x + 9 and 3x-5y=15. Then you could do 3x - 5(-3x+9) = 15. Finally solve for x and plug in x into both equations to see if you get the same y value.
The answer should be (10/3, -1)
Multiply 72×80 or 8. (I'm not sure of its 8 or 80).HOPE THIS HELPS YOU:)
