Answer: Choice C. 
==========================================================
Explanation:
The boundary line is a solid line and it's horizontal. Every point on the boundary line has y coordinate -1. So y = -1 is the equation of the boundary line. We can write it as y = 0x-1.
The shading is above the boundary line, so the inequality is
Any point (x,y) in the shaded region has y coordinate that is y = -1 or greater.
For example, the point (0,2) in the shaded region has y coordinate y = 2, and it satisfies the inequality because 
is a true statement.
Note: the boundary line is solid, so any point on the boundary line is part of the shaded solution set. This is due to the "or equal to" as part of the inequality sign.
X is the number
30(x²)=8x
minus 8 both sides
30x²-8x=0
factor out 30x
30x(x-8/30)=0
set each to zero
30x=0
x=0, nope, we said x can't be 0
x-8/30=0
x=8/30
x=4/15
the number is 4/15
Answer: There are five "digits": 0,1, 2, 3, 4
Step-by-step explanation: The base is five. There are five "digits": 0,1, 2, 3, 4 . Positions correspond to integer powers of five, starting with power 0 at the rightmost digit, and increasing right to left. The digit placed at a position shows how many times that power of five is included in the number.
For Right angled triangle area
A=ab/2
(2x-2)(4x+2)/2
(8x^2+4x-8x-4)/2
(8x^2-4x-4)/2 take common term 2
2(4x^2-2x-2)/2
So A=4x^2-2x-2
