You would use the equation
F+V=E+2
Answer:
.25 X 4 = 1
.50 X 2 = 1
.10 X 10 = 1
Step-by-step explanation:
:)
Vertex = (2, 2)
Range = {f(x): f(x) >= 2}
Answer:
4 km per hour and 6 km per hour.
Step-by-step explanation:
The combined running rate = 30/3 = 10 km/h.
If one runner's speed = x then the other one's speed is x+2 km/h.
So x + x + 2 = 10
2x = 8
x = 4
So one runs at 4 km/h and the other at 6 km/h.
