Answer:
13,780.8 feet
Step-by-step explanation:
1 mile = 1.609km
1 mile = 5,280ft
Convert 4.2km to miles
1.609km = 1 mile

= 2.610 miles
Convert 2.610 miles to feet
1 mile = 5,280ft
2.610 miles = 2.610 × 5,280
= 13,780.8 feet

Answer: <em>f(x) </em>= 21 .The output is 21 when the input is 5.
Step-by-step explanation:
f(x) = 4x+1 Substitute the input, 5, for x on the right side <em> f(x) is the equivalent of y, the output you are looking for</em>
<em>f(x) </em>= 4(5) + 1
<em>f(x) </em> = 20 +1
<em>f(x) </em>= 21
