I don't know all 12, but I can tell you some.
1. Shade the side of the line that satisfies the inequality.
2. If the inequality sign has an "or equal to" line under it, make the line on the graph connected.
3. If the inequality sign does not have an "or equal to" line under it, make the line on the graph dashed.
4. Isolate y (or the variable that is being used), and keep it on the left side of the inequality.

Step-by-step explanation:
<u>Inscribed angle is half the intercepted arc measure.</u>
- m∠PQR = 1/2x
- x = 2m∠PQR
- x = 2(74°) = 148°

Answer:
28/5=x and y= -6/5
Step-by-step explanation:
solve by substitution
3x+4y=12
Rewrite equations:
2x+y=10;3x+4y=12
Step1: Solve 2x+y=10 for y:
2x+y=10
2x+y+−2x=10+−2x(Add -2x to both sides)
y=−2x+10
Step2: Substitute−2x+10 for y in 3x+4y=12:
3x+4y=12
3x+4(−2x+10)=12
−5x+40=12(Simplify both sides of the equation)
−5x+40+−40=12+−40(Add -40 to both sides)
−5x=−28
-5x/-5=-28/5
(Divide both sides by -5)
x= 28/5
Step3: Substitute
28/5 for x in "y=−2x+10":
y=−2x+10
y=−2(28/5)+10
y=-6/5(Simplify both sides of the equation)
Hope this helps!
