The work of a student to solve the equation 3(2x − 4) = 8 + 2x + 6 is shown below: step 1: 3(2x − 4) = 8 + 2x + 6 step 2: 5x − 7 = 14 + 2x step 3: 5x − 2x = 14 + 7 step 4: 3x = 21 step 5: x = 7 in which step did the student first make an error and what is the correct step? step 2; 6x − 12 = 14 + 2x step 2; 6x − 7 = 2(6 + x + 4) step 3; 5x − 2x = 14 − 7 step 3; 5x + 2x = 14 + 7

Based on the graph, what is the initial value of the linear relationship? a coordinate plane is shown. a line passes through the y-axis at -2 and the x-axis at 3.

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.
