Step-by-step explanation:
Answer:
(x, y) =(2,-3)
Step-by-step explanation:
4x+3y=-1
3x-9y=33 /:3
4x+3y=-1.....(1)
x-3y=11... (2)
(1)+(2): 5x=10
x-3y=11
x=10/5
x-3y=11
x=2
2-3y=11
x=2
-3y=11-2
x=2
-3y=9
x=2
y=9/(-3)
x=2
y=-3
(x,y)=(2,-3)

becuase some are sooo easy
Answer:
16
Step-by-step explanation:
use the acroname sohcahtoa
<em><u>sin </u></em><em><u>6</u></em><em><u>0</u></em><em><u>=</u></em><em><u>8</u></em><em><u>√</u></em><em><u>3</u></em><em><u>/</u></em><em><u>h</u></em>
sin60=0.8660 while 8√3=13.8564
divide both side by 0.8660
0.8660/0.8660=13.8564/0.8660
h=16.0
I'll just make a manual computation on how 1 member recruits his members until week 5. Then multiply the sum by 2.
old new
1: 1
2: 1 x 3 = 3 ⇒ 1 3 *only new members recruit 3 more
3: 3 x 3 = 9 ⇒ 4 9
4: 9 x 3 = 27⇒ 13 27
5: 27 x 3 = 81 ⇒ 40 81
40 + 81 = 121. Total number of members under 1 founding member.
121 x 2 founding members = 242 total number of members within 5 weeks.
