Since the problem is 2x^2-5xy-y^3 we first have to plug in what the x and y stands for, once you do that your problem should look like this:
2(-3)^2- 5(-3)(-2)- (-2)^3
Now take the parentheses away and when you do that your signs change.
2x3^2-5x(-3)x(-2)-(-2)^3
do it again with -5x(-3)x(-2)
2x3^2-30-(-2)^3
now do this with (-2)^3
2x3^2-30-(-8)
Now evaluate the power
3^2 becomes 9
2x9-30-(-8)
then change -(-8) to a positive since two negatives make a positive
2x9-30+8
Now multiply the numbers 2x9
18-30+8
Then do 18-30 which equals -12 then add 8
Now you are left with your answer:
<u>-4</u>

Answer:
Domain:
[-5,-2) U (-2,3.5) U (3.5,5]
Range:
[-3 0) U (0,5]
It is not a function because x = 1 has two different outputs (3 & 5)
Answer:
There are 6 equilateral triangles
you get an isosceles triangle
the height of the equilateral triangle is 4
this is all I have so far :)
The point where the lines intersect is the point that satisfies both equations.
It is (1, 5), selection C.
