You use 28% of your available sheets
28% = .28
500 x .28 = 140 sheets used
(0,500) (1,360)
m = 360-500/1-0
m = -140
y = -140x + 500
Answer:
Step-by-step explanation:
Let's calculate r of this G.P: (-20)/(4) = - 5(100)/(-20) = - 5So r = -5
The formula to find the nth term of a GP is;
a(n) = a(r)ⁿ⁻¹
<u />a₆ = a(r)⁶⁻¹
a₆ = 4(-5)⁵ = -12500<u />
