Uadrilateral abcd has coordinates a (3, 1), b (4, 4), c (7, 5), d (6, 2). quadrilateral abcd is a

AB ≅ DC and AD ≅ BC

slope of BC = slope of AD (m = 1/3), slope of AB = slope of DC (m = 3/1)

opposite sides are congruent and parallel so ABCD is a parallelogram.

parallelogram

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

45
