Answer:
-1.5 or -6/4
Step-by-step explanation:
Im assuming the equation is 4x+6=0
1.) subtract the 6 from each side.
4x= -6
2.) you need to isolate the X, so divide the 4 from each side.
X= -6/4 or -1.5
Answer:
First term = -41.
Common difference = -15.
Step-by-step explanation:
nth term: an = a1 + (n - 1)d where a = first term and d = the common difference.
-671 = a1 + (43 - 1)d
-806 = a1 +(52 - 1)d
-671 = a1 + 42d
-806 = a1 + 51d
Subtracting ( to eliminate a1):
-671 - (-806) = 42d - 51d
-9d = 135
d = -15
Substitute for d in the first equation:
-671 = a1 + 42*-15
-671 = a1 - 630
a1 = -671 + 630 = -41.
They are both equal to below zero
