Answer:
-1/4
Step-by-step explanation:
Multiplying 64 by -1/4 results in -16;
mult. -16 by -1/4 results in 4,
and so on.
The common ratio is -1/4.
X + 4 y = 19
y = - 2 x - 4
------------------
x + 4 * ( - 2 x - 4 ) = 19
x - 8 x - 16 = 19
- 7 x = 29 + 16
- 7 x = 35
x = 35 : ( - 7 )
x = - 5
y = 10 - 4
y = 6
Answer:
A ) ( - 5 , 6 )
