The cost of a jacket increased from $50.00 to $56.50. What is the percentage increase of the cost of the jacket?

Anyone know? is appreciated! will mark brainliest if correct!

Hardest math question of all time can you solve the equation. check for extraneous solutions.9∣9-8x∣ = 2x+3

Ialready asked this but i never got an answer. will give a high rating and perhaps brainliest. choose the linear inequality that describes the graph. the gray area represents the shaded region. y ≤ –4x – 2 y > –4x – 2 y ≥ –4x – 2 y < 4x – 2
