Answer:
see below
Step-by-step explanation:
The ratio of terms that are two terms apart (s4 and s6) is the square of the common ratio:
s6/s4 = r^2
r = √(8/18)
r = 2/3 . . . . . matches choices A and C
__
Using the formula for the general term, we now know enough to find the first term:
sn = s1·r^(n-1)
s4 = s1·(2/3)^(4-1)
Using s4 = 18 and multiplying by (2/3)^-3, we get ...
18·(2/3)^-3 = s1 = 18·27/8
s1 = 243/4 . . . . . matches choice A

Answer:
y = 9 - 5x
[x = -1] 14
[x = 0] 4
[x = 4] -11
Step-by-step explanation:
Step 1: Define
y + 5x = 9
x = -1, 0, 4
Step 2: Solve for <em>y</em>
y = 9 - 5x
Step 3: Plug in values of <em>x</em>
y = 9 - 5(-1) = 14
y = 9 - 5(0) = 4
y = 9 - 5(4) = -11
Change 2/3 to decimal point ( 2/3 = 0.67)
$450 x 0.67 = $301.50 (total sale price)
$450 - $301.50 = $148.50 (final price paid)
so, Wally paid $148.50 for the Desk.
