It depends on the data type. if you want to show an increase or decrease in something, you want a LINE GRAPH. if you want to show the difference between more than one variable, i would use a BAR GRAPH.

Answer:
n = 5
Step-by-step explanation:
Coordinate of P = (n,3)
R is on y-axis & the y-coordinate of P & R are equal. So coordinate of R = (3,0)
Coordinate of Q = (n,-2)
Using distance formula,
Distance between P & Q = 


Distance between P & R = 


But in question it is given that distance between P & Q is equal to the distance between P & R. So,

 
        
             
        
        
        
When b=0
f(x)=ax^2+c
test each
A. with x^2-1, A is false
B. with -x^2-1, B is false
C. cannot find contradiction
D. the axis is actually x=0, 0 is nithere positive nor negative, false
answer is C
        
                    
             
        
        
        
Answer:
Rotation of 90° (CounterClockwise)	(x, y)	(-y, x)
Rotation of 180° (Both Clockwise and Counterclockwise)	(x, y)	(-x, -y)
Rotation of 270° (Clockwise)	(x, y)	(-y, x)
Rotation of 270° (CounterClockwise)

Answer:
35 degrees
Step-by-step explanation:
The sum of all angles in a triangle equals to 180
To find angle z, just subtract 55 and 90 from 180
180-55-90= 35
Angle z = 35 degrees
