Rational because it can be expressed as a fraction.
Answer: After 5 minutes, the plane is at 20,000 feet. It descended a total of 10,000 feet.
Step-by-step explanation:
f = feet above ground
r = rate of descent
m = minutes
f = 30000 - r · m
f = 30000 - 20000m
After five minutes:
f = 30000 - 2000(5)
f = 30000 - 10000
f = 20000

Answer:
x=2
Step-by-step explanation:
Step 1: Simplify both sides of the equation.
−12x+26=x
Step 2: Subtract x from both sides.
−12x+26 − x = x − x
−13x+26=0
Step 3: Subtract 26 from both sides.
−13x+26−26=0−26
−13x=−26
Step 4: Divide both sides by -13.
−13x/−13 = −26/−13
x=2
