Answer:
No
Step-by-step explanation:
Substitute the coordinates of the point into the left side of the inequality, evaluate and compare.
4(- 4) + 5(2) = - 16 + 10 = - 6 > - 7
Thus (- 4, 2 ) is not a solution
 
        
             
        
        
        
3x+5y=16 is linear equation........
        
             
        
        
        
A ray is a line that has a begining point, but no end point
 a ray is 1 dimentional, it only goes one direction, left and right
a plane is 2 dimentional and extends indefinitely
it goes left and right and up and down
think of it like this
you have a piece of paper with no height
you draw a line starting at a point on the paper and it goes infinitely in the other direction
the paper is a plane, the line on it that has a starting point is the ray
 
        
                    
             
        
        
        
Answer:
1
Step-by-step explanation:
If there is nothing by the (x) in the equation there is always an invisible 1 next to it. The full equation is f(x)= 1x+3. The answer is 1. Hope that helps! 
 
        
                    
             
        
        
        
C = 2r in terms of r is
C/2 = r
The answer is C/2 = r
