All of them because they can't be multiply by nothing more than 1 Exept 27
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.
The answer is B, if you substitute x with 0 1 or 2 the result will always be 0

Answer:
Speed = 25miles per hour
Step-by-step explanation:
Represent the time with x and the distance with y
So, from the attachment; we have the following details:
Required
Determine the constant speed
Because the train travelled at a constant speed, the speed can be calculated using:
Notice that the result of each division is the same.
Hence, the constant speed is:
Speed = 25miles per hour
