Given two points; A(x₁,y₁) and B(x₂,y₂), the slope "m" is:
m=(y₂-y₁)/(x₂-x₁) or m=(y₁-y₂)/(x₁-x₂)
Therefore:
(-9,5)
(-7,10)
m=(10-5) / (-7-(-9))=5/(-7+9)=5/2
Answer: D. 5/2
The first equation will turn into -18x -6y = -18, and the second equation will turn into 14x + 6y = 18. The y terms will cancel out when you add the equations together.
So basically, we have [-83, -77] as the whole thing.
There's a circle that limits [-83, -79) as a shaded zone.
Vera claims that -78.9999 X, which is false.
Vera wrote a relation symbol that doesn't represent the ray's direction. She went the other way around.
Answer:
tatlong Lugar na posibleng paglaruan ng luksong tinik
2.8 miles.
My Work/Reasoning:
First we find the rate. 7/60 mpm (miles per minutes)
Then we multiply that by 24. 7/60 * 24
Finally, we solve the equation and learn that Chang would run 2.8 miles in 24 minutes.
