The slope of the line below is -2. Which of the following is the point-slope
form of the line?
O A. y+ 4 = -2(x-8)
O B. y+8=-2(x-4)
O C. y-4 = -2(x+8)
O D. y-8 = -2(x + 4)

the 4th choice is the correct one

step-by-step explanation:

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

question

given the diagram below, what is md?

the sum of the interior angles is 360°

take away from 360 the sum of the knows angles and you will have the angle d.

360 - 108 - 108 - 72 = 72°
