Ihonestly don’t know what to put here anymore

You cannot combine a variable and a constant. However, note that the denominator is the same. So what you put is:

a/b + 8/b = (a + 8)/b

a + 8 is your answer

hope this helps

i dont know

step-by-step explanation:

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.
