PLZ HELP FAST 20 points 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 andy 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 =

I think it says 5 point what class

sorry, i'm new here and i'm just trying to figure this out. try quizlet. rate 5* you!

from the figure we get,

the x axis shows   the months and,

the y-axis shows the number of satisfied customer.

each line or each cell in upward direction (y-axis) shows 500.

the appropriate scale for the y - axis is: -

a = 2000 customers

b = 4000 customers

c = 6000 customers

d = 8000 customers

e = 10000 customers

f = 12000 customers

g = 14000 customers
