Find the annual interest rate. i=$160, P=2000, t=8 months

0.12 or 12%

Step-by-step explanation:

I=Prt

r= I/(Pt)

r = 160/(2000 x 8/12)

r = 160/(4000/3)

r = 3/25

r = 0.12

answer:   x = 3 + √11     and     x = 3 - √11

step-by-step explanation:

x² - 6x + 9 = 11

(x - 3)² = 11

x - 3 = ±√11

    x = 3 ± √11

x = 3 + √11     and     x = 3 - √11

where does the z at is it on the x axes or on the y axes any way if it is on the y axes put it horizontally and if it is on the x axes put it vertically
