A pair of equations is shown below: y = 3x - 5
y = 6x - 8
Part A: Explain how you will solve the pair of equations by substitution or
elimination. Show all
the steps and write the solution. (5 points)
Part B: If the two equations are graphed, at what point will the lines representing the
two equations intersect? Explain your answer. (5 points)

3.17 scores on stats final. below are final exam scores of 20 introductory statistics students. 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 57, 66, 69, 71, 72, 73, 74, 77, 78, 78, 79, 79, 81, 81, 82, 83, 83, 88, 89, 94 (a) the mean score is 77.7 points. with a standard deviation of 8.44 points. use this information to determine if the scores approximately follow the 68-95-99.7% rule. (b) do these data appear to follow a normal distribution? explain your reasoning using the graphs provided below.

The input to the function is x and the output is y. write the function such that x can be a vector (use element-by-element operations). a) use the function to calculate y(-1.5) and y(5). b) use the function to make a plot of the function y(x) for -2 ≤ x ≤ 6.

Lines a and b are perpendicular. if the slope of line a is 3, what is the slope of line b?
