Answer:
(-3, -1); x = -3; y = -1
Step-by-step explanation:
-3x + 5y = 4; x + y = -4
solving via substitution
rearrange second equation: y = -x - 4
-3x + 5(-x - 4) = 4
-3x - 5x - 20 = 4
-8x -20 = 4
-8x = 24
x = -3
- 3 + y = -4
y = -1
(-3, -1)
Check
- 3 + -1 = -4
means the nth term is 4 times the previous term
first term is 0.5
means the next one is 0.5 times 4 or 2
hum, geometric sequence
we can write it as
where
is the nth term
is the first term
is the common ratio (what you multiply each term by to get the next term)
is which term
so first term is 0.5
common ratio is 4
so therfor
answer is E
