Answer:
   y < -1/4x -1
Step-by-step explanation:
The boundary line appears to go through the points (-4, 0) and (0, -1). This tells you it has a "rise" of -1 for a "run" of 4. The slope is ...
   m = rise/run = -1/4
The y-intercept (b) is the point where the y-axis is crossed. The slope-intercept equation of the boundary line is ...
   y = mx + b
   y = -1/4x -1
__
The boundary line is dashed, so is not included in the solution set. The shading is below the line, so all y-values less than (but not equal to) the boundary line are in the solution set:
   y < -1/4x -1
 
        
             
        
        
        
<span>A. cos(x) = cos(-x)  [correct, since cos(x) is an even function]
B. Since the cosine function is even, reflection over the x-axis [y-axis] does not change the graph.  [false]
C. cos(x) = -cos(x)   [ false]
D. The cosine function is odd [even], so it is symmetrical across the origin.   [false]</span>
        
                    
             
        
        
        
This is how you work it out:
u + xy
Plug in your numbers that you know:
20 + 9 * 8
20 + 72
92
        
                    
             
        
        
        
D.) <span>A picnic table is on sale for 40 percent off. The original price of the picnic table is x, $144.10
It is on sale for 40% so, new amount will be 60%, and x is the sale price, so in order to calculate original price, you have to multiply them
Hope this helps!</span>
        
             
        
        
        
The area of a rectangle can be calculated by the product of its length and the width. Here we are given the area and the length so we can simply calculate for width. The perimeter is the sum of all the side lengths of the shape. We calculate as follows:
Area = lxw
1/6 = 1.5w
w = 1/9
Perimeter = 2l + 2w
Perimeter = 5/9
Hope this answers the question. Have a nice day.
