x + x-5 + x +23 = 180
combine like terms:
3x +18 = 180
subtract 18 from each side:
3x = 162
divide both sides by 3
x = 162 / 3 = 54
Angle x = 54 degrees
Angle x-5 = 54-5 = 49 degrees
Angle x +23 = 54 +23 = 77 degrees

simplify
Answer: the domain is negative infinity to positive infinity
Step-by-step explanation:
the graph covers all x values
3x+4y=5
2x+3y=
-2(3x+4y)=5(-2)
3(2x+3y)=4(3)
-6x-8y=(-10)
6x+9y=12
Add the equations
-6x-8y=(-10)
+ 6x+9y=12
-----------------
0x+y=2
y=2
Substitue y into an equation
6x+9(2)=12
6x+18=12
6x=-6
x = -1
y = 2
