assume you have collected data pairs ( x, y) on a certain variety of tree. x is the number of weeks since the tree was planted and y is the height of the tree in inches. a plot of the data points with the best-fit line is given below. what is the numerical value of the height as predicted by the best-fit line for an age of 40 weeks?

What is the next step in the given proof? choose the most logical approach. a. statement: m 1 + m 2 + 2(m 3) = 180° reason: angle addition b. statement: m 1 + m 3 = m 2 + m 3 reason: transitive property of equality c. statement: m 1 = m 2 reason: subtraction property of equality d. statement: m 1 + m 2 = m 2 + m 3 reason: substitution property of equality e. statement: 2(m 1) = m 2 + m 3 reason: substitution property of equality
