Answer:
y = 2.09x2 + 0.33x + 3.06
Step-by-step explanation:
You can draw the area bounded by the unequality

in following way:
1. Draw a dashed line

with a slope

(a dashed, because all points from this line, for example when x=0, y=-2 do not belong to the area);
2. Define which part (under the line or over the line) is suitable by substituting values. For example, when x=0 and y=0 you obtain that

is a right unequality, that means that the point (0,0) is a solution and belongs to the area;
3. Shade that part of the plane to which point (0,0) belongs, you receive the area over the line (see image).
From the done steps you can see that only fourth statement is true.
Answer:

Answer:
An expression that represents how much money gary will have left over after the purchase = (10x + 7) - 2y
Step-by-step explanation:
The number of dollars owned by Gary = 10 x + 7
Gary decides to buy two pairs of jeans.
Let the cost of one pair of jeans be y
Cost of two pairs of jeans be represented as 2 y.
An expression that represents how much money gary will have left over after the purchase = (10 x + 7) - 2 y
