You will need to add 3 to each side.
x^2-3=15
+3 +3
x^2=12
and go from there
Answer:
A to B = 2000 m/s
C to D = 30,000m/s
Step-by-step explanation:
A to B is 10secs and the distance is 200m so you multiply them and you get 2000m/s
C to D is 60secs and the distance is 500m so you multiply and you get 30,000m/s
Y = -2x + 8 <=== this would be ur equation where x is the number of hrs and y is the total distance (in miles) from home
