The sum of two numbers is 38. the greater number is 8 more than the other number. find each number. use a system of linear equations to justify your answer

Call x and y the 2 numbers.

x + y = 32

x - y = 8

2x = 40 -> x = 20, and y = 32 - 20 = 12.

answer: on graphs, the open and closed circles, or vertical asymptotes drawn as dashed lines us identify discontinuities.

as before, graphs and tables allow us to estimate at best.

when working with formulas, getting zero in the denominator indicates a point of discontinuity.

when working with piecewise-defined functions, check for discontinuities at the transition points where one piece ends and the next begins.

i believe it's a.

i'm not sure on this one, most likely correct.
