Divide both sides by f then cancel out
Answer:
f(5.9)= 15.7
Step-by-step explanation:
f(x) = 3x -2
f(5.9) = 3(5.9) -2
f(5.9) = 17.7 -2
f(5.9) = 15.7
Word Explination
If the (x) in f(x) is replaced by another variable (in this case, a number) any other x seen in the equation is replaced by that variable. For this question, the x in f(x) is replaced by 5.9. And so any other x in this equation needs to be replaced by 5.9 as well. From there on out, you solve.
Step-by-step explanation:
5 miles
using the formula
time = 
, then his distance can be calculated
+ 
= 1
+ 
= 1
= 1 ( multiply both sides by 30 )
6d = 30 ( divide both sides by 6 )
d = 5
He lives 5 miles from school
