given: a(2,1), b(0,5), c(-1,2), ab and bc, mpab = 1/2, mpbc = -1/3, midpoint of ab = (1,3), midpoint of bc = (-1/2, 7/2).

a) -x+2y=5
b) -x-2y= -5
c) -c-3y= -10
d) -x-2y=6
e) -x-3y=10

arithmetic sequence

step-by-step explanation:

given that a sequence has terms as

19, 15, 11,

this is represented on a graph

the pattern indicates that the sequence is an arithmetic sequence with i term

a=19 and common difference d =-4

any general term

thus the sequence is reduced by 4 for each successive term starting from 1 and nth term is

24-5n.

first negative term would start after 5th term

5th term =24-25< 0

from 5th term onwards the sequence would be negative.

the answer is c.

step-by-step explanation:

answer: -0.5 would be the most likley outcome

step-by-step explanation:

answer: 7 x 2/5 = 2.8 hours, is your answer. your welcome! : 3

step-by-step explanation: first work out how long it took to hose 1/7 of the lawn which is 2/5 hours. times that by 7 to get the whole lawn.

sorry i don't know the other answer. i didn't learn what a proportional relationship is.
