Between the median and the number before it and everything in front of it is the lower quartile
Step-by-step explanation:
-4.5x -2y = -12.5 -------(1)
3.25x -y = -0.75 --------(2)
From (2) we can make y the subject of the relation
y = 0.75+3.25x -------(3)
Input 0.75+3.25x into y in (1)
-4.5x -2(0.75+3.25x) = -12.5
-4.5x -1.5- 6.5x = -12.5
-4.5x -6.5x -1.5 = -12.5
-11x = -12.5 +1.5
-11x = -11
x = 11/11
x = 1
If x = 1,substitute 1 into x in (3)
y = 0.75+3.25x
y = 0.75 +3.25(1)
y = 0.75 +3.25
y = 4
x = 1,y = 4
Answer:
Refer the attached figure.
Step-by-step explanation:
Given : System of equation 
To find : Which graph represents the solution to the given system?
Solution :
Equation 
plotted with a red line passing through (-1,0) and(0,4).
Equation 
plotted with a blue line passing through (0,-3) and(0.75,0).
As their slopes are equal i.e. m=4.
So, the equation of lines are parallel.
There is no solution of the equations.
Refer the attached figure of the equations.
Answer:
56m
Step-by-step explanation:
X + 8 = 0.5
Take away 8 from both sides:
x = 0.5 - 8
x = -7.5
Answer: x = -7.5
