<u>Answer:</u>
- The x coordinate is known as <u>abscissa</u><u> </u><u>(</u><u>B)</u>
 
<u>Step-by-step</u><u> Explanation</u><u>:</u>
In a Cartesian plane, we learn many such terms which represent a point, or a line, or cooridnates of some points etc
Such terms are:
- Origin (Intersection of x axis and y-axis.)
 - x - axis (Horizontal line)
 - y - axis (Vertical line)
 - abscisaa (x -coordinate)
 - ordinate (y - coordinate)
 
 
        
             
        
        
        
Answer:
-2x + 8
Step-by-step explanation:
8 is y intercept. 2 units down and one to the right. -2/1 so -2
 
        
                    
             
        
        
        
Answer:
V ≈ 2011 cm³
Step-by-step explanation:
The volume (V) of a cylinder is calculated as
V = area of base × perpendicular height
V = πr²h ( r is the radius and h the height )
Here r = 8 and h = 10, thus
V = π × 8² × 10
   = π × 64 × 10 = 640π ≈ 2011 cm³ ( to nearest whole number )
 
        
             
        
        
        
2√72 / √8 ± √2
If the denominator is √8 + √2,
2√72 / √8 + √2
= 2√(2*2*2*3*3) / √(2*2*2) + √2
= 2*2*3√2 / 2√2 + √2
= 12√2 / 3√2
= 4
