<h3>
Answer: Bottom left corner (southwest corner)</h3>
The left endpoint is x = 4, but we don't include this endpoint because of the open hole. We use a parenthesis to indicate "don't include the endpoint"
The right endpoint is positive infinity. We always use a parenthesis with either infinity since we cannot reach infinity
The interval from 4 to infinity is written as which is like saying 
Y+1=[m(the slope)](x+2), y=mx+2m-1, it is impossible to get the answer without the graph.
Answer:
x + 12 = 4 * (x - 15) --> x = 24

Answer:
41.0501 ft²
Step-by-step explanation:
Area of a Sector (Radians): A = 1/2r²∅
We are given <em>r</em> and ∅, so simply plug it into the formula:
A = 1/2(5.6)²(5π/6)
A = 1/2(31.36)(5π/6)
A = 15.68(5π/6)
A = 41.0501 ft²
