Find the midpoint, M, of AB

To answer what the midpoint of AB is simply replace the values in the formula to find the coordinates of the midpoint.

In this case these are (2 + 4) / 2 = 3 and (6 + 18) / 2 = 12. So (xM, yM) = (3, 12) is the midpoint of the segment defined by A and B.

the inequality is:

250c+180g≥950

step-by-step explanation:

let c denotes the number of days in a week   miyoko worked as a cryptographer.

and g denotes the number of days in a week she works as a geologist.

now we are given that she earns $250 for every day she works as a cryptographer,and earns $180 for every day she works as a geologist.

now miyoko's goal is to earn more than $950 this week.

hence, the inequality could be represented as:

250c+180g≥950

step-by-step explanation:

one of the most important purposes of surface treatment is to alter surface properties according to the requirement of specific applications. for example, hydrophobic coating has been utilized on windshield and eyeglasses. gold atom monolayer on substrate has become a popular surface bioconjugation strategy.
