Answer:
X=7-3y
is the equation formed here
Answer:
$460.38
Step-by-step explanation:
Use the exponential decay formula, y = C(1 - r)^t
Plug in the original price, depreciation rate, and amount of time:
y = 20000(0.875)^11
y = 460.38
So, the car's value after 11 years will be $460.38
Answer:
see explanation
Step-by-step explanation:
Since the triangles are similar then the ratio of corresponding sides are equal
(a)
=
, substitute values
=
( cross- multiply )
13.23AB = 111.132 ( divide both sides by 13.23 )
AB = 8.4
(b)
=
, substitute values
=
( cross- multiply )
6.3DF = 54.243 ( divide both sides by 6.3 )
DF = 8.61
