PLEASE IF YOUR A MATH EXPERT ANSWER THIS I'M LOSING MY SANITY What is the value of 7m−3n when m = 3 and n = 2?
A: 5
B: 15
C: 24
D: 36

B: 15

Step-by-step explanation:

To answer this question, simply plug in the values according to each variable. So, because m = 3, plug the m next to 7 with 3, so then that means that 7 is now multiplied by 3. Then, plug in 2 into n because n = 2, so 3 is being multiplied to n. This is what we get:

7(3) - 3(2)

Now, multiply!

21 - 6

Finally, solve:

21 - 6 = 15

Therefore, the answer is:

B: 15

Hope this helps :)

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.
