Consider this formula. Z = @ Macmillan Learning If z = 4.0 and y = 5.6, what is the value of x? Express your answer to the tenths place (i.e., one digit after the decimal point). X=Appendix A Problems 8. If you haven't practiced in a while, let's calculate some slopes. In each case, we give two points, and you can use the "rise over run" formula to get the right answer. Enter fractions in decimal form, with two decimal places. @ Macmillan Learning a. Point 1: x = 0, y = 0. Point 2: x = 3, y = 6 Slope: b. Point 1: x =6, y = -9. Point 2: x = 3, y = 6 Slope: c. Point 1: x =4, y = 8. Point 2: x = 1, y = 12 Slope:Rearrange the equation to isolate X. CD A = X @ Macmillan Learning X = If C = 6.00, D = 9.00, and A = 2.00, what is the value of X? X = If A is halved while C and D remain constant, what happens to the value of X? The value of X is halved. The value of X is tripled. O The value of X does not change. O The value of X is doubled
