We need y = mx + b.
Here, b is the y-intercept.
-17 = -6(8) + b
-17 = -48 + b
-17 + 48 = b
31 = b
Answer: Time taken =1.25 x 10^1 hours 0r 4.5 x 10^4s
Step-by-step explanation:
Step 1
how long will it take the rocket to make the trip from Earth to the satellite = Time taken for the rocket to make the trip from Earth to the satellite
Speed = Distance / Time ,
Time = Distance / speed
Step 2-- solving
Time = Distance / speed
Time=2.5×10^5 miles/2.0×10^4 miles per hour
=12.5 hours = 1.25 x 10^1 hours
or 1.25 x 10^1 hours x 3600 = 45,000 seconds = 4.5 x 10^4s

Answer: x ≥ - 3
5x - 1 ≥ -4(x + 7)
⇔ 5x - 1 ≥ - 4x -28
⇔ 5x + 4x ≥ - 28 + 1
⇔ 9x ≥ - 27
⇔ x ≥ - 3
