The system of inequalities can model Gabrielle’s situation is;
x + 2y ≤ 20
x + 2y ≤ 203x + 2y ≤ 21
<h3>Inequality</h3>
It follows from the task content, that the inequalities which can be used to model Gabrielle's situation be determined.
By setting variables as follows;
- batches of brownies = x
- batches of cookies = y
Brownie:
Sugar = 1 cup
Eggs = 2
Cookie:
Sugar = 3 cups
Eggs = 2
x + 2y ≤ 20
x + 2y ≤ 203x + 2y ≤ 21

The the parabola opens upward it has a minimum and if it opens downward then it has a maximum :)
The expansion of the expression is 
<h3>How to expand the expression</h3>
Given the expression;
-2/20 (1 - 2x + 2)
= 
× (1 -2x +2 )
Open up the bracket by multiply with -2, we have
= 
Collect like terms in the numerator
=
Thus, the expression of the expression is

Draw six dots then a plus sign then draw seven dots and the count them and put an equal sign and however many dots. Doe the same with the other numbers
This is what it is asking. There can be also other numbers above. These are just the basic numbers for tenths.
