Ok, since y varies inversely as x , the equation is y=k/x....... Then you plug in 2 for y and 25 for x to find K....... After that you get K= 50...... Then plug in 50 for K and 40 for y then solve for x....... After that you get X= 1.25!!!!! :)
This is a graph of the two equations. This would then prove that the answer is d. None of the above. I’m unsure of this but Let me know if I’m correct
Answer:
A. 0.25x - 6.50
Explanation:
(3x - 1) - 2.75 (x + 2)
= 3x - 1 - 2.75x - 5.5
=0.25x -6.5
Hence A is equivalent to 0.24x -6.5
