Answer:
-b/a
Step-by-step explanation:
The slopes of perpendicular lines are negative reciprocals. That means that their product is -1.
slope of line = a/b
slope of perpendicular = -b/a
R-s=c but I'm not for sure
Answer:
6x ² - 10x - 56
Step-by-step explanation:
(3x -7) (2x +8)
To expand this, each term in the first bracket would multiply the other bracket.
3x(2x +8) -7( 2x + 8)
6x ² + 24x - 14x - 56
6x ² + 10x - 56

Answer:
Can Ou please explain.
Step-by-step explanation:
Answer:
distance down wind
d - 6 = distance back
time = distance ÷ speed
x = d/20
x = (d - 6)/(16)
so d/20 = (d - 6)/16. Cross multiply
20d - 120 = 16d
-120 = -4d
30 = d so the whole trip assuming the bird gets back to the starting point is 60 miles
