The points ABC have coordinates (3,5)(7,8)(6,1) respectively. show by calculation that AB is perpendicular to AC. also find the equation for AC in the Form ax+by+c=0 where a, b, c are integers whose value must be stated. also the point D is on AC produced and AC:CD =1:2, find the coordinates of D.​

0.84 dang lotta people are looking for this lol or if you round up its 1 but the overall answer to that is 0.84

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

unless if u could do my questions, if not i wouldn't want to
