Answer :
Answer:
k = 4
Step-by-step explanation:
f(x)=5x+k
Let x =2
f(2) = 5*2 +k
f(2) = 10+k
We know f(2) = 14
14 = 10+k
Subtract 10 from each side
14-10 = 10+k-10
4 =k
We are given the function f(x) = 5x + k when k is a constant, x equals 2, and f(x) equals 14
Steps to solve:
14 = 5x + k; x = 2
~Substitute
14 = 5(2) + k
~Simplify
14 = 10 + k
~Subtract 10 to both sides
14 - 10 = 10 - 10 + k
~Simplfy
4 = k
Best of Luck!
