When you are solving problems for distance, speed and time, you will find it helpful to use diagrams and/or charts to organize the information and help you solve the problem. You will also apply the formula that solves distance, speed/rate and time which is distance = speed/rate times time:
<span>d = rt</span>
Find the diameter of circle using pythagoras
d = √(Δx² + Δy²)
d = √((7-1)² + (-6-2)²)
d = √(6² + (-8)²)
d = √100
d = 10
The diameter is 10
Find the circumference
c = π × d
c = 3.14 × 10
c = 31.4
x = unknown number (that is a solution/makes the inequality true)
When the inequality sign is </> (less than/greater than), the dot is an open circle.
When the inequality sign is ≤/≥ (less than or equal to/greater than or equal to), the dot is a closed circle.
14.) The line has an open circle on -8, and a closed circle on 11.
-8 < x ≤ 11 [x is any number greater than -8 and less than or equal to 11]
15.) The line has a closed circle on -14 and 5.
-14 ≤ x ≤ 5 [x is any number greater than or equal to -14 and less than or equal to 5]

Answer:
D
Step-by-step explanation:
Multiplying the inequality by 2 will eliminate the fraction and give you ...
x ≤ 36
The "or equal to" part of the symbol means the end dot will be solid. The "less than" part of the symbol means the graph is shaded to the left of the end dot, which is at x=36. This description matches the graph shown below.
