1. Determine whether b = 23 is a solution to b + 27 = 50. A. Since 621 + 50, 23 is not a solution to b + 27 = 50.
B. Since 73 + 50, 23 is not a solution to b + 27 = 50.
O C. Since 50 = 50, 23 is a solution to b + 27 = 50.
D. Since –4 + 50, 23 is not a solution to b + 27 = 50.

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.

step-by-step explanation:

constant of proportionality = 3 and the equation is c = 3p.

step-by-step explanation:

c = kp   where c = amount of caffeine in mg., p = oz of pepsi and k is the constant of proportionality.

substituting the values given:

24 = 8k

k = 3.

the same value of k will be obtained if we substitute the other given values.
