Answer: Choice A) -312,500
=====================================
The long way to find the answer is to multiply each term by -5 until you've generated 8 terms total.
4 is the first term
-20 is the second term (4 times -5 = -20)
100 is the third term (-20 times -5 = 100)
100 times -5 = -500 which is the fourth term
-500 times -5 = 2500 which is the fifth term
2500 times -5 = -12500 which is the sixth term
-12500 times -5 = 62500 which is the seventh term
62500 times -5 = -312500 which is the eigth term
---------------------
A shortcut is to use the formula below
a(n) = a*(r)^(n-1)
Plug in a = 4, r = -5 and n = 8
a(n) = a*(r)^(n-1)
a(8) = 4*(-5)^(8-1)
a(8) = 4*(-5)^7
a(8) = 4*(-78125)
a(8) = -312,500
and we get the same answer
Answer:
Step-by-step explanation:
first plug in zero for x to find y and do the same thing when u want y to graph put in y=mx+b form
[2*8+(20-12)]/6=4
2*(8+20)-12/6=54
I hope it helps :)
Answer:
x = 46
Step-by-step explanation:
First, we know that -31/3 + x/6 = -8/3. Now, add 31/3 to both sides to get 23/3 = x/6. So multiply by 6 to get 46.
Hope this helps!
