Answer:
The 5th term.
Step-by-step explanation:
a3 = a1 + 2d = 4
a9 = a1 + 8d = -8
Subtracting :
6d = -12
d = -2
So it's the 5th term because:
a5 = a3 + 2(-2)
= 4 - 2(2) = 0
4x+36+5=3×-8 is the answer
26
a triangle is 180 degrees add 120 + 34 to get 154
180 -154 = 26
y-0= -1(x-5)
y= -x+5
x+y-5=0
-2
-2x+1x=-2
