Answer:
(3(6)-1)/(2(6)+1)
Step-by-step explanation:
See attached image.
(x - 7)(y - 9)
x*(y - 9) - 7*(y - 9)
x*y - x*9 - 7*y -7*(-9)
xy - 9x - 7y + 63
That's the product.
Answer:
0.50
Step-by-step explanation:
Solution:
When a function f(x) is stretched vertically by a factor of an integer n, it implies that the new function g(x) is n times its old function.
Thus,

Given a square root function, we have
![f(x)=\sqrt[]{x}](https://tex.z-dn.net/?f=f%28x%29%3D%5Csqrt%5B%5D%7Bx%7D)
When the function is stretched by a factor of 6, let the new function be represented as G(x). This implies that
![\begin{gathered} G(x)=6\times f(x) \\ =6\times\sqrt[]{x} \\ \Rightarrow G(x)=6\sqrt[]{x} \end{gathered}](https://tex.z-dn.net/?f=%5Cbegin%7Bgathered%7D%20G%28x%29%3D6%5Ctimes%20f%28x%29%20%5C%5C%20%3D6%5Ctimes%5Csqrt%5B%5D%7Bx%7D%20%5C%5C%20%5CRightarrow%20G%28x%29%3D6%5Csqrt%5B%5D%7Bx%7D%20%5Cend%7Bgathered%7D)
Hence, the new function G(x) will be expressed as
![G(x)=6\sqrt[]{x}](https://tex.z-dn.net/?f=G%28x%29%3D6%5Csqrt%5B%5D%7Bx%7D)
The correct option is A.
