Question

find which ordered pairs from a given set are a part of the solution set for the inequality
2y+3x≤9 (-1,8) (0,0) (2,2) (3,2)

Answer 1

You only need substitute the x and y values for the ones given in each ordered pair; if the inequality holds true then that ordered pair is a part of the solution set. (Or, you could solve the equation and see which values correspond to the ordered pairs given.)

Answer 2

plug every point into the inequality
1. -3+16=13>9 no
2. 0+0=0 <9 yes
3. 2*2+3*2= 10>9 no
4. 3*3+2*2=13>9 no

so only (0,0) satisfied

Answer 3

thanks cong guo

Answer 4

i always just need the first equation and i can go from there lol

Answer 5

sometimes cant understand whats i am to do lol
