Susan was given the math problem x - 4 + -11. She found the answer to be 7. Critique her answer. Is she correct? How do you know? PLS ANSWER ASAP!!! <3

she was wrong

Step-by-step explanation:

x-4-11 = 0 (4+-1=4-1)

x=15

hence she was wrong

table 3 represents a direct variation function. : )

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.
