k=9
Step-by-step explanation:
4/3 = 8/6 = 12/9
![\frac{-1}{18}](https://tex.z-dn.net/?f=%5Cfrac%7B-1%7D%7B18%7D)
Solution:
Given expression is ![\frac{y}{3}=-6](https://tex.z-dn.net/?f=%5Cfrac%7By%7D%7B3%7D%3D-6)
To find the inverse of y.
⇒ ![\frac{y}{3}=-6](https://tex.z-dn.net/?f=%5Cfrac%7By%7D%7B3%7D%3D-6)
Do cross multiplication.
⇒ y = –6 × 3
⇒ y = –18
Inverse of y means reverse the function.
We know that inverse of y is
.
⇒ ![\frac{1}{y}= \frac{-1}{18}](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7By%7D%3D%20%5Cfrac%7B-1%7D%7B18%7D)
Hence, inverse of y is ![\frac{-1}{18}.](https://tex.z-dn.net/?f=%5Cfrac%7B-1%7D%7B18%7D.)
Answer:
The perimeter of the triangle can be expressed as 5x + 18.
Step-by-step explanation:
Perimeter of an object is the sum of the length of its sides.
For the required triangle, we have;
length of the base = x
length of the second side = 3x + 9
length of the third side = x + 9
Perimeter of the triangle = length of the base + length of the second side + length of the third side
= x + (3x + 9) + (x + 9)
= x + 3x + 9 + x + 9
= 5x + 18
The perimeter of the triangle can be expressed as 5x + 18.
Answer:
c
Step-by-step explanation:
first, find the area of the rectangle thing,
A = lw
14 x 8
112
but, there is a semicircle in it so you need to subtract that from it:
A = πr^2/2
A = π(4)^2/2
A = π16/2
A = 8π
A ≈ 25.132741228718346
then subtract that area from the area of the rectangle:
112 - 25.132741228718346
86.867258771281654
or about 89.9
