Answer:
g(6) = 12
Step-by-step explanation:
g(x) = 1/2x + 9
To find g(6), replace x with 6 in the expression and evaluate it.
g(6) = 1/2 * 6 + 9
g(6) = 3 + 9
g(6) = 12
Okay so the first one is 3 dollars each..because if you subtract 9 from 21 you will be left with 12 dollars so if he spent the money on FOUR tickets it would be 3 because 3 times 4 is 12 :)
The simplified area function in terms of y for a rectangle is 
<u>Solution:</u>
Given that length of each side of a square = y
Need to determine area of rectangle whose length is twice the length of the square and width is 2 units longer that the side length of square
Length of rectangle = twice of side length of square = 
Width of rectangle = 2 + side length of square = 2 + y = y + 2

On substituting length and width in formula for area, we get

Hence function
is represents area of required rectangle.
