Answer:
a) no
b) yes
c) yes
d) no
Step-by-step explanation:
Angle LJM is complementary to KJL, so is ...
angle LJM = 90° -42° = 48°
Angle NJP is marked as congruent to angle PJQ, so is also 48°.
__
a) ∠KJL = 42° ≠ 48° = ∠LJM . . . . NO
b) ∠MJP = 46°+48° = 48° +46° = ∠PJR . . . . YES
c) ∠LJP = 48° +46° +48° = 48° +48° +46° = ∠NJR . . . . YES
d) ∠MJK = 90° ≠ 48° +46° = ∠PJR . . . . NO

Answer:
The correct answer is the first option: (5, -2) (3, 1) (-4, 2)
Step-by-step explanation:
Given the following systems of linear inequalities:
y ≥ -1/2x and y < 1/2x + 1:
Plugging in the values of (5, -2) (3, 1) (-4, 2) into the given systems of linear inequalities provides a true statement:
y ≥ -1/2x:
(5, -2): y ≥ -1/2x
-2 ≥ -1/2(5)
-2 ≥ -2.5 True statement.
(5, -2): y < 1/2x + 1
-2 < 1/2(5) + 1
-2 < 3.5 True statement.
(3, 1): y ≥ -1/2x
3 ≥ -1/2( 1 )
3 ≥ -1/2 True statement.
(3, 1): y < 1/2x + 1
1 < 1/2(3) + 1
1 < 2.5 True statement.
(-4, 2): y ≥ -1/2x
2 ≥ -1/2(-4)
2 ≥ 2 True statement.
(-4, 2): y < 1/2x + 1
2 < 1/2(-4) + 1
2 < -1 True statement.
Therefore, (5, -2) (3, 1) (-4, 2) are the solutions to the systems of linear inequalities.
