First we see there are two extremes, two limits
-2 and 5
x is between them
BUT theres a difference , the point at left is black
the point at right is white rounded
this means x is equal or less than -2
and x is ONLY less than 5 , not equal
so this means the answer is the d option
Answer:

Answer:
This
Step-by-step explanation:
let x = rate of the slower plane (First plane!)
x+25 = rate of the faster plane (Second plane!)
The planes fly for 2 hours, where Distance = R*T
Distance between the planes = SUM of the distances.
R*T + R*T= 470 miles
2*x + 2*(x+25)=470
2x+2x + 50 = 470
4x+50=470
4x=420
x=105 mph First plane
x+25= 105+25=130 mph Second plane.
