The particle will reach 50 km/hr when x = 32.25 hours
Step-by-step explanation:
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 - 4 x + 3 y = 21, where
- x is the time in hours
- y is the velocity in kilometer per hour
We need to find when a certain particle will reach 50 km/h
∵ - 4 x + 3 y = 21 is a linear function
∵ x represents the time (number of hours)
∵ y represents the velocity in km/h
∵ The velocity of a particle will reach 50 km/h
- Substitute y by 50 in the function above
∴ - 4 x + 3(50) = 21
∴ - 4 x + 150 = 21
- Subtract 150 from both sides
∴ - 4 x = -129
- Divide both sides by -4
∴ x = 32.25 hours
The particle will reach 50 km/hr when x = 32.25 hours

45 = 1/2(a - 65)
90 = a - 65
155 = a
Let the width be w.
Length = 3w - 6
Perimeter = 460
w + w + 3w - 6 + 3w - 6 = 460
8w - 12 = 460
8w = 472
w = 59
Width = w = 59 yards
Length = 3w - 6 = 3(59) - 6 = 171 yards
Answer: Length = 171 yards and Width = 59 yards
