A physicist working in a large laboratory has found that light particles traveling in a particle accelerator increase velocity in a manner that can be described by the linear function −4x + 3y = 21, where x is time and y is velocity in kilometers per hour. Use this function to determine when a certain particle will reach 40km/hr.

The particle will reach 40km/hr when x =

Answer:

Velocity of particle (y) = 40km/hr Rearrange equation to be 4x = 3y-21 Therefore 4x = 3*40-21 = 99 x = 99/4 = 24.75 hours

Step-by-step explanation:
