The sum of two numbers is 53 and the difference is 27. what are the numbers?

The numbers are 39 and 14.

Step-by-step explanation:

Equation 1, sum of the numbers:

x  +  y   =  53

Equation 2, difference of the numbers:

x  -  y  = 25

System of equations:

x  +  y  =  53

x  -  y   =  25

2x = 78

x = 39

Solve for y:

39  +  y  = 53

y  =  14

The numbers are 39 and 14.

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.
