HELP PLEASE Which expressions are equivalent to 2(3/4x+7) -3(1/2x + -5)? Check all that apply.​

2., 3., 5.

Step-by-step explanation:

when we do the multiplications we see

2×3x/4 + 2×7 - 3×1x/2 + 3×5 = 3x/2 + 14 - 3x/2 + 15 = 29

as 3x/2 and -3x/2 reduce themselves in a sum to 0.

this gives answer option 2.

the other correct answer options are just splitting the addition part in a multiplication into their 2 "sub-multiplications" and adding these results.

the only correct ones (correctly maintaining our converting the signs) are 3 and 5.

option 4 suddenly converts the -3 factor into +3 without any other compensation. so, that is wrong.

and option 1 made again a sign mistake with -3×-5, which is correctly +15 and not -15.

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.
