AB and BC form a right angle at point B. If A = (2, -5) and B = (8, 3), what is the equation of BC? (A) 2x + 6y = 7

(B) 3x - y = 21

(C) x + 3y = 17

(D) 3x - y =1

it could 14.28 but if its not that one then it has to be the 17 one. hope this ! : )

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

3/20

step-by-step explanation:

well, there are 20 outcomes, and 3 of them you want. so, 3/20

step-by-step explanation: hi!
