Answer:
53
Step-by-step explanation:
If x = 9 and y = 3, then we have to find the value of [tex]|1 - 2x| + 4y^{2}[/tex].
The problem is simple and we have to put the values of x and y in the expression.
Let, [tex]A = |1 - 2x| + 4y^{2}[/tex].
⇒ A = [tex]|1 - 2(9)| + 4(3)^{2}[/tex]
⇒ A = [tex]|1 - 18| + 4\times (9)[/tex]
⇒ A = [tex]|- 17| + 36[/tex]
[Here, we must define the function |x|.
|x| = x for x ≥ 0 and |x| = - x for x < 0
Now, here x is less than zero and it is - 17.
So. |x| = - x = - ( -17) = 17 ]
⇒ A = 17 + 36
⇒ A = 53 (Answer)
