Answer:The slope is -6/23 or 6/-23 since the negative sign can be on the numerator or denominator, or in the middle. However, you cannot have a negative sign on the numerator and denominator at the same time for negative number or it will make it positive.
Step-by-step explanation:
Delta y/Delta x=
y2-y1/x2-x1=
12-18/11-(-12)=
-6/23
27$ because you do 20*15*12 then 3600*0.09 and divide that answer by 12 which is 27
Answer with explanation:
Relation between Speed , Distance and time
Distance =Speed × Time
→It means Speed is inversely Proportional to time.
As distance will remain constant , in that frame of reference
If speed of light in a Medium

Then, time taken to cross the medium = t seconds or hours or another unit of time.
Now, If speed of light is 50% of the speed of light relative to us
That is Speed of light in another medium

Then, time taken to cross the medium = 2t seconds or hours or another unit of time.
Using Unitary Method
