Abc is located at a (2, 0), b (4, 4) and c (6, 3). zackery says that abc is an isosceles triangle while verna says that it is a right triangle. who is correct?
a. zackery because linebc=lineac
b. zackery because lineab=linebc
c. verna because linebc _|_ lineac
d. verna because lineab _|_ linebc

If you are ever struggling with a word problem with coordinates, you should always graph it so you can see what it means.

We see that B and C don't exactly line up, so it's not a right triangle.

Therefore, we can eliminate answers C and D.

The answer should be B. Zackery because line AB = line BC.

the answer to the question is a

step-by-step explanation:

it has the same slope and the same y-intercept.

y + 11 = -7/9(x - 18)

y + 11 =-7/9x + 14

b

y = -7/9x + 3

y-intercept (0, 3)

step-by-step explanation:

the original amount doesn't ''re just looking for the time it takes for 1/2 of the substance to we have

(1/2) =)     take the ln   of both sides

ln (1/2)   = )   and we can write

ln(1/2) = ) lne     and lne   = 1     so we have

ln(1/2) = -.1092t     divide both sides by -.1092

t = ln(1/2)/-.1092 = about 6.347 days = about 6.3 days (rounded)
