One of the first walking robots had a top speed of 1 mph, or 1.6 kmh. Today's model of that robot can run about 4 mph. What is the robot's speed in kmh?

check above link.

graphically?   well, you graph them both, the solutions is where they both intersect each other, since there are two solutions, meaning they will meet twice, or namely the linear will run into the quadratic curve twice, and where they meet, those x,y coordinates are the solutions to the system.

the awnser is visionary

1. 523.33 cubic inches

2. 113.04 cubic inches.

3. 17.41.

4. 16.49

i think this should be your answer

hope i
