At a supermarket every can of tomatoes weighs at least 15 ounces. Let ω represent the weight of a can of tomatoes. Which inequality represents the situation.
Choices: w < 15, w > 15, w ≤ 15, w ≥ 15
Please help which one is the answer?

Write numerical coefficient of y² in the expression 2x² - 15xy – 7y²

The first few steps in solving the quadratic equation 9x2 + 49x = 22 ? 5x by completing the square are shown. 9x2 + 49x = 22 ? 5x 9x2 + 54x = 22 9(x2 + 6x) = 22 which is the best step to do next to solve the equation by completing the square? 9(x2 + 6x + 3) = 25 9(x2 + 6x + 3) = 49 9(x2 + 6x + 9) = 31 9(x2 + 6x + 9) = 103
