Answer:
$4138.7
Step-by-step explanation:
P= $3,900
R= 2%
T or n= 3 years
compounded anually (yearly) so:
A= P(1+
)
A= 3900(1+
)
A= $4138.7
2 / 3 *x * 3= 2 x
10 * 3 = 30
2 x/ 2 = 1 x
30 / 2 = 15
X=15
Inverse variation means
When the value of x increases the value of y decreases.
When the value of x decreases the value of y increases.
So for an inverse variation we have the expression

or

The expression which represents this condition is

Hence option b) or the second option is the right answer.
Answer:
x = 138
Step-by-step explanation:
Exterior angle thm:
68 + 70 = x
x = 138
