Answer: Yes, it is.
First you have to subtract X on both sides.
9x-9x+11y=-9x+15
equals
11y=-9x+15 (You cannot combine unlike numbers)
You divide both sides by 11.
11y/11= -9x+15/11
Y= -9/11 X+15/11
Although it doesn't look so, graphing calculators online will show that this answer in linear.
Answer:
Circumference = 2πr
69.08 = 2× 3.14 × r
69.08 ÷ 6.28 = r
11m = r
the answers are
7/10
306/1000
1/100
9/1000
hope this helps!
