Answer:
22) 119
24) 15
Step-by-step explanation:
22) 61 + b = 180 <-- supplementary because on the same line
b = 119 <-- subtracted 61 from both sides
24) 87 + (6x + 3) = 180 <-- supplementary because on the same line
87 + 6x + 3 = 180 <-- take out parantheses
90 + 6x = 180 <-- add like terms
6x = 90 <-- subtracted 90 from both sides
x = 15 <-- solve for x by dividing 6 from both sides

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 ![2x+4y=3.](https://tex.z-dn.net/?f=2x%2B4y%3D3.)
All another options contain some inequalities that do not include the line ![2x+4y=3.](https://tex.z-dn.net/?f=2x%2B4y%3D3.)
