Which two line segments are skew?

a. lines de and ge
b. lines ei and gk
c. lines gk and dh
d. lines hi and df

Skew lines are two lines that do not intersect and are not parallel.

Consider all options:

A. Lines DE and GE intersect at point E, then they are not skew lines.

B. Lines EI and GK are parallel, then they are not skew lines.

C. Lines GK and DH are parallel, then they are not skew lines.

D. Lines HI and DF lie in two parallel planes IKJH and EGFD, respectively. Then these lines do not intersect. Lines HI and DF are not parallel, then these lines are skew lines.

correct choice is D

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

she drove 134 miles
