The point (–4, –2) is reflected across the x-axis.

what are its new coordinates?
(4, 2)
(–4, –2)
(–4, 2)
(4, –2)

(4,2)

Step-by-step explanation:

It's always just the reverse signs.

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

where are the choices?
