Answer:
The value of x for the expression is 2
Step-by-step explanation:
Given algebraic expression as :
(4 + 6 x ) =
x +
( x + 9 )
Now, solving the given expression
Or,
× 4 +
× 6 x =
x +
x +
× 9
Or,
+
× x =
x +
x +
or, 2 + 3 × x =
+
+ 6
or, 2 + 3 × x =
+ 6
or, 2 + 3 × x =
+ 6
Or, 2 + 3 × x = x + 6
or, 3 x - x = 6 - 2
Or, 2 x = 4
∴ x = ![\frac{4}{2}](https://tex.z-dn.net/?f=%5Cfrac%7B4%7D%7B2%7D)
I.e x = 2
Hence The value of x for the expression is 2 Answer
Answer:
![\boxed{\sf Option \ 3}](https://tex.z-dn.net/?f=%5Cboxed%7B%5Csf%20Option%20%5C%203%7D)
Step-by-step explanation:
When x is -2, F(x) is undefined.
When x is -1, F(x) is -3.
If we see the third option,
![F(x)=\sqrt{x+1} -3](https://tex.z-dn.net/?f=F%28x%29%3D%5Csqrt%7Bx%2B1%7D%20-3)
When x is -2, we get the square root of -1, which is undefined.
When x is -1, we get the square root of 0, which is just 0, 0-3 is -3.
