Answer:
x=8/3
y= -20/9
Step-by-step explanation:
4X + 3Y -4 =0
Linear egquations must in

so 4X + 3Y =4
THEN
3X + 9Y = - 12
next use calculator to solve it or you can use traditional way
Answer:
87.92 in²
Step-by-step explanation:
pi × (R² - r²) = area
Where R is the radius of the outer circle and r of the inner circle.
Since C = 2pi×r
37.68 = 2×3.14×r
r = 6 in
R = 6 + 2 = 8 in
Therefore,
pi × (R² - r²) = area
Area = 3.14 (8² - 6²)
= 87.92 in²
Answer-
<em>The inverse of
is </em>

<u>Solution-</u>
The given function is,

We can get the inverse by interchanging he variable x and y among themselves and then separating each variables.
So in the inverse would be,

Taking log of both sides,

As,

Applying the same,


As,

Applying the same,

Therefore, the inverse of
is
.
That would be 0.2
Hope this helps. :)
