Use inductive reasoning to predict the most probable next number in the list.
3, 9, −3, 3, −9, −3, −15, −9, −21, ?

the answer is -15

this is because from every pair of numbers (e.g 3,9) you are always adding 6.

apply this to -21 and you would get -15

the amount you'd have after the work is $1.55

step-by-step explanation:

you subtract 95% from $31.

step-by-step explanation:

. your answer will contain x - and y -terms. (1 point) x ( ¿¿ 2 − 7 ) 2 +( y 2 − 9 ) 2 √ ¿ 12. what is the distance from the directrix (the crocodile river) to the point ( x , y )? write this equation. your answer will contain a y -term.
