The nth term of any geometric sequence can be expressed as:
a(n)=ar^(n-1), a(n)=nth term, a=initial term, r=common ratio, n=term number...
We can easily see that the first term, a=-8
The common ratio is 4/-8=-2/4=1/-2=r=-1/2 so the rule is:
a(n)=-8(-1/2)^(n-1) so the tenth term is:
a(10)=-8(-1/2)^(10-1)
a(10)=-8(-1/2)^9
a(10)=1/64
Answer:C(3, –5) and D(6, 0) is;. 5x - 3y = 30.
Step-by-step explanation:
The equation of the line CD expressed in standard form which passes through the points C(3, -5) and D(6,0) is: 5x - 3y=30.

Answer:
ok
Step-by-step explanation:
Answer:
the answer is 12
Step 1. Perform the operations inside the parenthesis:
(4 + 9) − 3(6) ÷ 2 + 8 = 13 - 18 ÷ 2 + 8
Step 2. Division has advantage over subtraction and addition:
13 - 18 ÷ 2 + 8 = 13 - 9 + 8
Step 3. Subtract and add:
13 - 9 + 8 = 12
