Answer:
a
Step-by-step explanation:
a=-4 r=12/-4=-3
T7= ar^n-1
= (-4)(-3)^7-1
=-2916
I think u just subtract 35° from 130° and that should be the angle of x
Answer:
Option A, no trend
Step-by-step explanation:
<u>Since the points are all over the graph, that means that there is no trend.</u>
<u />
If all the points followed a straight line toward positive infinity, it would be positive trend.
If all the points followed a straight line toward negative infinity, it would be negative trend.
Answer: Option A, no trend
Y = -2x - 4
x + 4y = 19
x + 4(-2x - 4) = 19
x + (-8x) - 16 = 19
-7x - 16 = 19
-7x = 35
-x = 5
x = -5
y = -2x - 4
y = -2(-5) - 4
y = 10 -4
y = 6
Solution set {-5, 6} (C)
