Answer:
7/2
Step-by-step explanation:
The slope of the line is given by
m = (y2-y1)/(x2-x1)
= (-1-6)/(9-11)
= -7/ -2
= 7/2
Step 1: Simplify both sides of the equation.
17−2n=9
17+−2n=9
−2n+17=9
Step 2: Subtract 17 from both sides.
−2n+17−17=9−17
−2n=−8
Step 3: Divide both sides by -2.
−2n−2=−8−2
n=4
Answer:
A.
Step-by-step explanation:
Speed of the east bound cyclist is 12 mph and the speed of west bound cyclist is 15 mph.
<u>Solution:</u>
Let us assume that x is speed of slower eastbound cyclist
So, x+3 will be the speed of faster westbound cyclist
We know that distance is the product of speed and time. That is,

West-bound DATA:
Rate of speed = x+3 mph ; Time = 6 hrs ; distance = 6(x+3) = 6x+18 miles
East-bound DATA:
Rate of speed = x mph ; time = 6 hrs. ; distance = 6x miles
On solving,
Distance apart = 162



So, the rate of speed of the east bound cyclist is 12 mph and the rate of speed of the west bound cyclist will be 
-180 is the answer
