Hello!
Since the lines on are not dotted then the symbols have to be less than or equal to / greater than or equal to
If y was greater than or equal to x then we would have a line that goes through point (0, 0) and has the region above it shaded
This is what happens in the picture so we know that the answer is C
The answer is C
Hope this helps!

Step-by-step explanation:
Answer:
-x^8+10x^3-7x^2+7x+15
Step-by-step explanation:
-7x+10x^3-7x^2-x^8+15
Standard form is from highest power to lowest power of x
-x^8+10x^3-7x^2+7x+15
Answer:
A.
Step-by-step explanation:
5x^2 – 15x – 20
= 5(x^2 – 3x – 4)
= 5(x^2 – 4x + x – 4)
= 5{x(x - 4) +1(x - 4)}
= 5(x-4)(x+1)
