C. The measures must be supplementary bc a line is 180º and supplementary means 180º plus the angles are vertical of each other so that means they are on the same line. I hope this helps
Answer:
List the options so we can help you out here.
Thank you in advance.
here's the solution,
let the length of shorter peice = x
then the lenght of longer peice = 6x + 8
now, we know that the sum of length of peices measures 99 feet,
So,
=》x + 6x + 8 = 99
=》7x = 91
=》x = 13
shorter piece length = 13 feet
longer peice length = 13 × 6 + 8 = 78 + 8 = 86 feet
Graph both equations in your calculator and find out where they intersect. That point is your solution!
F(x) = x² + 7x + 8
f ¹ (x) = d/dx (x² + 7x + 8)
= (2*x) + (7*1) + h
= 2x + 7 + h
