Answer: 83
Step-by-step explanation:
(88+92+87+x)/4 = 90
(277+x)/4 = 90
x+ 277 = 360
x = 83
 
        
                    
             
        
        
        
H ( x ) = - 6 + x
m = 1 ( the slope )
b = - 6 ( y - intercept )
x - intercept: 
0 = - 6 + x
x = 6 
The graph is going through Quadrants:  I, II and IV.
Answer:
B ) Quadrant II, because the slope is positive and y-intercept is negative.
        
                    
             
        
        
        
<span>3. Two isosceles right triangles
Every square has 4 right angles, so each triangle will have one right triangle, which makes the triangles, right triangles. 
They are isosceles because all sides of the square are the same, though the diagonal is not.
Hope this helps :)
