Answer:
Rate = 0.45 or 45%.
Step-by-step explanation:
20184 = 9600(1 + r)^2
(1 + r)^2 = 20184/9600 = 2.1025
Taking square roots of both sides:
1 + r = 1.45
r = 1.45 - 1 = 0.45.

Answer:
(x, y)=(4,-8)
Step-by-step explanation:
9x+y=28
3x+3y=-12 /:(-3)
9x+y=28.......(1)
-x-y=4......(2)
9x+y=28
(1)+(2): 8x=32
9x+y=28
x=32/8
9x+y=28
x=4
9*4+y=28
x=4
36+y=28
x=4
y=28-36
x=4
y=-8
x=4
(x, y) =(4,-8)
D. y, because Triangle JHK is similar to triangle LMK
