Solve the following systems of inequalities and select the correct graph:

2x − y < 4
x + y < −1

in each graph, the area for f(x) is shaded and labeled a, the area for g(x) is shaded and labeled b, and the area where they have shading in common is labeled ab.

Option 2 is correct

Step-by-step explanation:

The system of inequality,

2x - y < 4

x + y < -1

First we draw the graph of both line. So make table of each line

x  :    -1        0        1

y  :    -6     -4       -2

Test point (0,0)

0 - 0 < 4

 0 < 4

True (Shade towards origin)

x  :    -1        0        1

y  :    0        -1       -2

Test point (0,0)

0 + 0 < -1

     0 < -1

False (Shade away from origin)

Plot the points graph.

answer

a,b, and d

explanation

a reflection angle is more than

but less than;

an angle that measures

is a reflex angle.(true)

an angle that measures less than

is acute.(true)

provided we are considering angles greater or equal to zero.

an acute angle lies in the range.

an obtuse angle is less than 180° but more than 90°

an angle that measures 300° is obtuse (false)

an angle that measures 65° is an acute angle.(true)
