Change the quadratic equation from standard form to vertex form. y=x^2+4x-5 1. Transpose the -value to the left side of the equation. 2. Complete the square of the expression on the right side of the equation to get a perfect square trinomial. Add the resulting term to both sides. 3. Add the numbers on the left and factor the trinomial on the right. 4. Transpose the number across to the right side to get the equation into the vertex form, y=a(x-h)^2+k . 5. Make sure the addition and subtraction signs are correct to give the proper vertex form.

Multiply. write your answer in simplest form. 3/8 x 5/7

The table shows the relationship between the number of cups of cereal and the number of cups of raisins in a cereal bar recipe: number of cups of cereal number of cups of raisins 8 2 12 3 16 4 molly plotted an equivalent ratio as shown on the grid below: a graph is shown. the title of the graph is cereal bars. the horizontal axis label is cereal in cups. the x-axis values are 0, 20, 40, 60, 80,100. the vertical axis label is raisins in cups. the y-axis values are 0, 10, 20, 30, 40, 50. a point is plotted on the ordered pair 40,20. which of these explains why the point molly plotted is incorrect? (a) if the number of cups of cereal is 40, then the number of cups of raisins will be10. (b)if the number of cups of raisins is 40, then the number of cups of cereal will be10. (c) if the number of cups of cereal is 40, then the number of cups of raisins will be 80. (d) if the number of cups of raisins is 40, then the number of cups of cereal will be 80.
