Answer:
200
Step-by-step explanation:
170% of x = 680
Set up an equation:
170/100 • x/1 = 680
1.7 • x = 680
1.7x = 680
x = 400
50% of 400
1/2 • 400 = 200

Answer:
The value of given function for x = - 3 is 9
Step-by-step explanation:
Given as :
The y is the function of x is as
f( x ) = x²
So, For any value of x , the value of f( x ) should change
If, x = - 3
So, f ( - 3 ) = ( - 3 )²
Or, f ( - 3 ) = ( - 3 ) × ( - 3 )
i.e f ( - 3 ) = ( - × - ) ( 3 × 3 )
Or, f ( - 3 ) = ( + ) ( 9 )
∴ f ( - 3 ) = 9
So, The value of function f ( - 3 ) = 9
Hence , The value of given function for x = - 3 is 9 Answer
