Answer:
u just expand the brackets out and make a linear equation to solve from there
Step-by-step explanation:
If you divide the first equation by 2 and the second by 3, you get

These equations differ only in their y-intercept, so describe parallel lines. The appropriate choice is ...
... H The lines are parallel.
The distance between the ships changing at 92.29 Knots
- Using the position of ship A as the reference point, at time t measured in hours past noon, ship A is 18 t miles west of this point and ship B is 40 + 17t north of this point.
- The distance between ships is then

The rate of change of distance is -

after putting t = 5 into this rate of change ,
we get, answer = 92.29

Answer:
q = 
Step-by-step explanation:
The point of intersection (3, 1 ) is the solution to both equations
Using
y = qx - 7 and substituting x = 3, y = 1
1 = 3q - 7 ( add 7 to both sides )
8 = 3q ( divide both sides by 3 )
= q
