Let f(x) = 12 over the quantity of 4 x + 2. Find f(−1).

Answers

The value of f(-1) is -6

what is function?

A function is defined as a relation between a set of inputs having one output each. In simple words, a function is a relationship between inputs where each input is related to exactly one output.

Given:

f(x) = 12/ (4x +2)

for x=-1

then,

f(-1) = 12/ ( 4(-1) + 2)

f(-1) = 12/ (-4 + 2)

f(-1) = 12/(-2)

f(-1) = -12/2

f(-1) = -6

Hence, the value of f(-1) is -6

#SPJ2
f(x)= 12 / (4x+2 )
f(-1) mean to replace x by (-1) 
so, f(-1) = 12 /(-4+2) 
f(-1)= 12/-2 
f(-1) = -6 

mike drove to a frineds house at the rage of 40 mph. he returned hoke by the dsne route at 45 mph the driving time for the round trip was four hours how long did it take mike to get home

Answers

Let the distance be x miles

Time = Distance / speed

Time taken by Mike to go to his friend's house = x / 40 hours

Time taken by him to return = x / 45 hours

Total time = x / 40 + x / 45 = 4 hours

= 9x + 8x = 1440 miles

17x = 1440

= x = 1440 ÷ 7

= x = 84.706

Time taken to return home = 84.706 /45= 1.882 hours .

Therefore , Mike took1.882hoursto reach home .
