Given:
baked: 6 <span>cookies and 4 brownies
can bake 25 more either </span><span>cookies or brownies
</span><span>Let x represent the number of more cookies that Midge can bake
Let y represent the number of more brownies that Midge can bake.
cookies = 6 + x
brownies = 4 + y
(6 + x) + (4 +y) </span>≤ 25
10 + x + y ≤ 25
x + y ≤ 25 - 10
x + y ≤<span> 15
y </span>≤ <span>15 - x
</span><span>The following graphs best represents the relationship between x and y is:

Answer:
The complex number belongs to the third quadrant of the complex plane.
Step-by-step explanation:
Let be . In the complex plane, if
(real component) and

belongs to the third quadrant of the complex plane.
Let the average profit or loss in year 2006 be x millions,
The average profit for the 8-year period, is the total sum of the profits (or losses) of each year, divided by 8:
so we have:
x=8-10.45=-2.45
Answer: the loss in 2006, was 2.45 million dollars
