Answer:
That equation doesn't make sense, so this equation means "no solution"
Step-by-step explanation:
Perpendicular lines have slopes that are negative reciprocals. example: line a has a slope of 2/3, line b has a slope if -3/2 if they are perpendicular.
Did this wrong sorry I thought it was greatest to least.

The equation of a elipse:

The length of the major axis is equal 2a if a > b or 2b if b > a.
We have

therefore the length of the major axis is equal 2 · 7 = 14.
Answer:
Week 16
Step-by-step explanation:
Week 1: 3.5 miles => 22.5 miles left
22.5/1.5 increments = 15 weeks
15 weeks + week 1 = 16th week
