Z+(z-6)-2=-10 work out the problem and show it to me

Mathematics
1 answer:
Akimi4 [234]3 years ago
3 0

Answer:

z = - 1

Step-by-step explanation:

z + (z - 6) - 2 = - 10 ← remove the parenthesis on left side

z + z - 6 - 2 = - 10 , that is

2z - 8 = - 10 ( add 8 to both sides )

2z = - 2 ( divide both sides by 2 )

z = - 1

The point B lies on the segment AC.
svet-max [94.6K]

Answer:

(9, -5)

Step-by-step explanation:

The vector AC has coordinates (27, -18), because:

21 - (-6) = 27

-13 - 5 = -18

If the ratio of AB to BC is 5 to 4, it means that

AB = [5/(5+4)]AC = (5/9)AC

Therefore, we have

AB = (5/9)AC = (5/9) (27, -18) = (15, -10)

Which means that:

xB - xA = 15 <=> xB - (-6) = 15 <=> xB + 6 = 15 <=> xB = 9

yB - yA = -10 <=> yB - 5 = -10 <=> yB = -10 + 5 <=> yB = -5

So B has coordinates (9, -5).
