Another formula for slope intecept form is rise/run
Answer:
(x, x2 -2x+8) where −5 ≤ x ≤ 3
Step-by-step explanation:
The given function is f(x)=x2- 2x+ 8
We want to select the option that describes all the solutions to the parabola.
The domain of the parabola is −5 ≤ x ≤ 3.
This means that any x=a on −5 ≤ x ≤ 3 that satisfies (a,f(a)), is a solution.
This can be rewritten as (a,-a2- 2a+ 8)
Therefore for x belonging to −5 ≤ x ≤ 3, all solutions are given by:
(x, x2 -2x+8) where −5 ≤ x ≤ 3.
Answer: 12 minutes per mile
Step-by-step explanation: 20 miles) / (4 hours) = (20/4) (miles/hours) = 5 miles per hour
(4 hours) / (20 miles) = (4/20) (hours/miles) = 0.2 hours per mile
I'm having the same troubles with this type of geometry sort of.
