Question

Please, Please, Please help!!!!!!!!!! I'll mark Brainliest!!!!!!!!!!!!!!!!
Explain if possible!

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+y=15, where x is time and y is velocity ion kilometers per hour. Use this function to determine when a certain particle will reach 30 km/hr.

Answer 1

Answer:

15/4

Step-by-step explanation:

You'll be solving for the time which is x, when y is at 30 km/h.

Plug the 30 into y.

-4x+y=15

-4x+(30)=15

-4x=-15

x=15/4
