You haven't shared "the given value of x," or, if you have, you haven't drawn attention to it.
Just suppose we were to choose x = 4 as a possible solution and then try to find a value of the parameter k that would make x = 4 an actual solution.
2(4) + 4k - 9 = (4)(4) - (4) + 1
Then 8 + 4k - 9 = 16 - 4 + 1, or 4k - 1 = 13. Then 4k = 14, and k = 14/4, or (after reduction) k = 7/2
If the parameter k equals 7/2, then x = 4 is a solution to the given equation.
To check this out further, start with the proposed solution x = 5 and find k.
<span>3x + 4y = 10
4y = -3x + 10
y = -3/4x + 5/2
or

answer: <span>C) f(x) = - 3/4 x + 5/2 </span>
Answer:
30
Step-by-step explanation:
120 / 20 = 6
5 × 6 = 30

Just subsitute the value of x with -2
f(-2) = 2×2(-2) = 2×(-4) = -8
Answer: -8
