The first one is correct! cuz the sides opposite the angles are 8 > 6 which is true
Answer:
Correct choice is A
Step-by-step explanation:
The line divides the coordinate plane into two semiplanes (top and bottom).
The inequality represents the region of all points (x,y) (including line ) which coordinates satisfy the inequality Actually, this region is top semiplane (red region).
The inequality represents the region of all points (x,y) (including line ) which coordinates satisfy the inequality This region is exactly bottom semiplane (blue region).
These two semiplanes intersect by line
All another options contain some inequalities that do not include the line
-7c+9=c+1 (subtract c on both sides)
-8c+9=1 (subtract 9 on both sides)
-8c=-8 (divide by -8 on both sides to get c by its self)
c=1
your answer is 1.
