jeremy claims that if a linear function has a slope of the same steepness and the same y-intercept as the linear function in the graph, then it must be the same function.

which equation is a counterexample to jeremy’s argument?

y= -1/2x-1

y= -1/2x+1

y= 1/2x -1

y= 1/2x+1

Without graphing the linear functions, find the coordinates of the point of intersection of their graphs: y=3x−11 and y=4

3x + 4y = 5 x- 3y = -7 solve by substitution

Using pert, adam munson was able to determine that the expected project completion time for the construction of a pleasure yacht is 21 months, and the project variance is 4. a) what is the probability that the project will be completed in 17 months? b) what is the probability that the project will be completed in 20 months? c) what is the probability that the project will be completed in 23 months? d) what is the probability that the project will be completed in 25 months? e) what is the due date that yields a 95% chance of completion?
