Answer:
True
Explanation:
If k = 2, then we plug in 2 for every instance there is a k. So...
8k + 4 > 18
Will turn into...
8(2) + 4 > 18
Then solve using PEMDAS (or whatever you were taught. Parenthesis, Exponent, Multiplication/Division, Addition/Subtraction.)
16 + 4 > 18
20 > 18
Since 20 is greater than 18, 2 can be a solution for this inequality.
