Answer:
The graph of given inequality is shown below
Step-by-step explanation:
The given inequality is
We need to find the graph of this inequality.
The related equation of the given inequality is
Table of values is
x y
0 4
-5 2
-10 0
Plot these ordered pairs on a coordinate plane and connect them by a dotted line.
The related line is a dotted line and shaded region lies above the line because the sign of inequality is <.

Answer:
lw + × π ×
⇒ Answer D is correct
Step-by-step explanation:
First, let us find the area of the semi-circle.
Area = × π × r²
<u>Given that,</u>
diameter of the semi-circle is ⇒ <em>l</em>
∴ radius ⇒ <em>l / 2</em>
<u>Let us find it now.</u>
Area = × π × r²
Area = × π ×
<u> </u>
Secondly, let us find the area of the rectangle.
Area = length × width
<u>Given that,</u>
length ⇒ <em>l</em>
width ⇒ w
<u>Let us find it now.</u>
Area = length × width
Area = l ×w
Area = lw
<u> </u>
And now let us <u>find the total area.</u>
Total area = Area of the rectangle + Area of the semi - circle
Tota area = lw + × π ×
Now plug the x value into 9x + 2
Hope that helps!
