<span>2(30)+2x=860
This is because the 4 sides of the rectangle add up to the perimeter.
The unknown side is x, and there are two of those, and there are also two sides of 30.
They all add up to the perimeter.
So:
2(30) + 2x = 860</span>

Answer:

Step-by-step explanation:
The straight line passes through (0,1) and (2,-2).
Equation of a straight line passing through two points (x1,y1) and (x2,y2)
is given by:



Everything to the left of the line is shaded.
We have to visualize the graph:the straight line has a positive y-intercept and a negative slope.The graph is given in the attachment below.
From the figure we can see origin lies on the shaded region.Hence (0,0) should satisfy the inequality.
LHS=y=0
RHS=
LHS<RHS as 0<1
Hence , the inequality is:
