C: Rotation of 90 degrees.
Answer:
See below
Step-by-step explanation:
<h3>Part A</h3>
Gas in liquid state at
- 40° F < t < 140° F
<h3>Part B</h3>
The graph is the line segment from the point -40 to 140 on the number line, with both points open circles and shaded in between those 2 points
Solution set is all numbers greater that -40 and smaller than 140.
<h3>Part C</h3>
-49° F is smaller than -40° F, so the gas would freeze
The answer is distribute property
A = (2 , 8 )
B = ( 7 , -5 )
therefore, midpoint of AB
( x1 + x2/2 , y1 + y2/2 )
→ ( 2 + 7/2 , 8 + (-5)/2 )
→ 9/2 , 3/2
→ 4.5 , 1.5
<em>so,</em><em> </em><em>option </em><em>B </em><em>is </em><em>correct</em>

Answer:
1. 10 : 24 = 5 : 12 = 20 : 48 = 40 : 96
2. 2 : 3 : 5 = 4 : 6 : 10 = 8 : 12 : 20
