Okay so this took some time but
you need 1 more cup.
in each cookie there is 1/9th of a cup so to make 45 cookies you need 1 more cup. WE COULD BE COMPLETELY WRONG
C.
6 is a constant, so we know that y is greater than or equal to 6.
x is just a variable, but it has to be positive, so it could be anything greater than or equal to 0.
Total flour = white flour + wheat flour, therefore y = x + 6.
-4x-8>-20
+8 +8
-4x>-12
Divide by 4 on both sides
x<3
Should be A.
Hope this helps.
Put your points in a graphing calculator and it will show you the answer
