The answer is y>1/2x+2
y is greater than one half x plus 2
Answer:
~ 3 1/2 days
Step-by-step explanation:
Mr.Tram travels at a constant speed of 60 km per hour, and travels for up to 8 hours per day (max). Multiply 8 with 60:
60 x 8 = 480
Next, divide 480 from 1620 to get the amount of days:
1620/480 = 3.375
~ 3 1/2 days is how long Mr.Tram will take to travel from Dallas, TX to Detroit, MI.

Since there is a power of 2 and constants, without a variable power of 1, I would use square root method.
Move the 7 to the right and you get 2x^2 = 16
Then divide both sides by 2 and get x^2 = 8
Now take the square root of each side and get x = +-sqrt 8
sqrt 8 can be simplified since 2*4 = 8 and 4 is a perfect square.
Therefore the final answer is x = +-2sqrt2
