Let x be the old price
X= 1200$
The price decreased 20% after 1 year to become price y :
Y= 0.8x
= 0.8 (1200)
= 960$
In the year after y also decreased 20% to be price y’:
Y’= 0.8y
= 0.8 (960)
= 768 $
The price y’ then decreased 20% to become price y’’:
Y’’ = 0.8 y’
= 0.8 (768)
= 614.4 $
Then the price will be 614.4 $ after 3 years
Answer:
slope = -1/5
Step-by-step explanation:
The slope of a line between two points is ...
slope = (change in y)/(change in x)
= (-1 -0)/(5 -0) = -1/5
The slope of the line is -1/5.
34.48
(2/7=.29, 10/.29=34.48)
1.1 Pull out like factors :
-8x - 2 = -2 • (4x + 1)
2.1 Divide both sides by -2
Remember to flip the inequality sign:
2.2 Divide both sides by 4
x+(1/4) ≥ 0
Solve Basic Inequality :
2.3 Subtract 1/4 from both sides
x ≥ -1/4
