Answer is <span>C. 9x-2y=-40
hope that helps
because y = 9/2x +20 then 2y = 9x + 40 so 9x -2y = -40
</span>

means you shade the part above the line, and

means you shade the part under the line.
If it has an equal bar under it, like this:

, then you also shade the line, by making it solid instead of dotting it.

Answer:
Step-by-step explanation:
a) (a + b)² = (a + b) * (a +b)
(a + b)³ = (a + b) * (a +b) * (a +b)
a²- b² = (a +b) (a - b)
Here (a + b) is common in all the three expressions
HCF = (a + b)
b) (x - 1) = (x - 1)
x² - 1 = (x - 1) * (x + 1)
(x³ - 1) = (x - 1) (x² + x + 1)
HCF = (x -1)
