Answer:
a8 = 0.004
Step-by-step explanation:
Q is abt a geometric series given by the eqn: an = a1*r^(n-1)
given a1 = 40000, r = 0.1
an = 40000*(0.1)^(n-1)
a8 = 40000*(0.1)^(8-1)
= 40000*(0.1)^7
= 0.004
1) To solve for x, is to let x on the left side and the other terms and variables on the right side.
bx -10=f <em>Add 10 to both sides</em>
bx = f+10 Divide by b on both sides
So that's the way we solve for x.
b) For this one we multiply the whole expression by 2 and then isolate z on the left side, and the rest on the right side.
z = 2h +2b

I would say B. By multiplying the first equation by -5, you create -5y. If you add that to the second equation, your cancelling out the 5y term, and get a new equation with only z and a constant.
