Answer:
Options (1) and (5)
Step-by-step explanation:
Expression that defines the function is,
Option 1
So, is false.
Option 2
f(0) =
=
True.
Option 3
f(1) =
=
= 2
Therefore, f(1) = -1 is false.
Option 4
Therefore, f(2) = 1 is false.
Option 5
f(4)
True.
Options (1) and (5) are the correct options.
so confusing i really need help with this math
The boat uses 4 gallons to travel 6 miles. Traveling 4 times as far is expected to require 4 times the gas.
4 gallons = 6 miles
Multiply by 4.
16 gallons = 24 miles
⇒ 16 gallons
So,
To divide a fraction by a fraction, all you need to do is invert the second fraction and multiply the resulting fractions.
Step 1: Flip the second fraction.
Step 2: Multiply the fractions.
