Copy and complete the steps for simplifying the expression below. Use properties to justify as many steps as possible 2d + 11 - 5d - 4 = 2d + 11 + (-5d) + (-4) = 2d + (-5d) + 11 + (-4) = d(2 +(-5)) + 11 + (-4) = -3d + 7

The data in the table represent the height of an object over time. which model best represents the data? height of an object time (seconds) height (feet) 05 1 50 2 70 3 48 quadratic, because the height of the object increases or decreases with a multiplicative rate of change quadratic, because the height increases and then decreases exponential, because the height of the object increases or decreases with a multiplicative rate of change exponential, because the height increases and then decreases
