Which line is perpendicular to a line that has a slope
of - 1/3
line mn
line ab
line ef
line jk

For this case we have to by definition, if two lines are perpendicular then the product of its slopes is -1, that is:

So, if we have the slope

A perpendicular line will have a slope m_ {2}:

Thus, the perpendicular line will have slope

The perpendicular line will have slope

Line EF

Step-by-step explanation:

The correct answer is Line EF because of two reasons:

1. It is the only line that has a slope of 3,

and

2. I got it correct on edg.

:)

the first one, all those points on the line just make a strait line.

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
