Answer:
Correct graph is C
Step-by-step explanation:
Given two inequalities are:
1.
2.
Step1 : Remove the inequalities
1.
2.
Step2 : Finding intersection points of equations
By solving linear equation
Replacing value of x in any equations
we get,
Therefore, Point of intersection is (-0.5,2.5)
Step3: Test of origin (0,0)
Here, If inequalities holds true for origin then, shades the graph towards the origin.
For equation 1.
True, Shade graph towards origin.
For equation 2.
True, Shade graph towards origin.
Thus, Correct graph is C
C
a ratio of 5 : 5 simplifies to 1 : 1, which basically means we require the midpoint of the line segment
using the midpoint formula
M = [ (0 + 20 ),
(15 + 0)] = (10, 7.5 )
