Answer:
y=-1/3x +29/3
Step-by-step explanation
We know that the line perpendicular to a slope of 3 is it's opposite reciprocal. So the slope is -1/3. Substitute -5 as X and 8 as Y so you get:
8= -5/3x +b.
B= 29/3
That's your answer.
 
        
             
        
        
        
28 divided by 4= 7
7-3=4
answer: 4 notebooks left.
        
                    
             
        
        
        
4500  = 4.5 * 10^3
57 = 5.7 * 10^1
730 = 7.3 * 10^2
0.007 = 7 * 10^-3
300.25  = 3.0025 * 10^2
56,325.2 = 5.63252 * 10^4
        
                    
             
        
        
        
Set up trig ratio using tangent. 
Tan theta = opp/adj
Tan theta = 500/800
Tan^-1 (500/800) = 32 degrees
        
             
        
        
        
Answer:
the y coordinate is 5
Step-by-step explanation:
In the figure attached, the  directed line segment is shown.
J is located at (-3, 1) and K is located at (-8, 11) 
run: x2 -x1 = -8 - (-3) = -5
rise: y2 - y1 = 11 - 1 = 10
Taking J as reference, the coordinate of the point that divides the  directed line segment from J to k into a ratio of 2:3 is:
c = 2/(2+3) = 0.4
(x1 + c*run, y1 + c*rise)
(-3 + 0.4*-5, 1+0.4*10)
(-5, 5)
