(a). 8x + y = 20, where (b). y = x2 - 2x + 4
So where y is in equation (a), substitute in the value of y in (b).
8x + (x2 - 2x + 4) = 20
8x + (4) = 20
Get rid of the 4 on both sides (since what you do to one side, you must do to the other)
8x + 4 - 4 = 20 - 4
8x = 16
Get rid of the 8 to leave x on its own
8x ÷ 8 = 16 ÷ 8
x = 2
So now that you have x, find y but substituting in the value you just found (2) into one of the starting equations.
8x + y = 20 where x is 2.
8(2) + y = 20
16 + y = 20
Minus 16 from both sides
y = 20 - 16 = 4
So x is 2 and y is 4
1/3 of the dimensions means to divide the dimensions by 3. This is to figure out what 1/3 of the dimensions are.
Our length is 6, and our width is 9.
Let's divide our length first.
6/3 = 2.
Our length with 1/3 of it's original dimensions is 2.
Let's divide our width now.
9/3 = 3.
Our width with 1/3 of it's original dimensions is 3.
Our dimensions are 2 by 3.
Your answer is A.) 2 in. by 3 in.
I hope this helps!

-1/4 is less then 1/2 because -1/4 is negative and 1/2 is positive and also -1/4 is 25% and 1/2 is 50%
