Answer:
9x^2-9x-3
Step-by-step explanation:
3x*3x=9x^2
3x*-4=-12x
1*3x=3x
1*-4=-3
9x^2-12x+3x-3
9x^2-9x-3
Answer:
The area of the circle is 
Step-by-step explanation:
we know that
The area of a circle subtends a central angle of
radians
so
By proportion find the area of the circle

5 * 10 raise to power of - 4
Part A.
We could take, for example:

For x ≥ -3 we have vertical line (x-intercept = -3) and shaded region on the right side of the line.
For y ≥ 3 we have horizontal line (y-intercept = 3) and shaded region above that line.
Part B.
Simply, substitute x and y coordinates of D and E <span>to the system of inequalities from part A, and check if its is true, what we get.
</span>

so point D is a solution,

and point E is also a solution to <span>our system of inequalities.
</span>
Part C.
There are two ways we could do that. First is the same as in part B. We substitute x and y coordinates of each school and check if inequality is true or false:


So Timothy can attend schools C and F.
We can also draw a graph of that inequality (pic 2).
