A solution to a equation is when the variable is substituted fully. That makes the equation true.
Okay. So, the line shaded would have to be left to 2, because it's less than 2. In that case, A and C are eliminated, because they shade to the right, not left. B and D do this, but wait. The dotted line has to represent the less than, because the one that's fully filled in would mean less than or equal to. B would make sense, because the line is dotted and that makes an inequality symbol of less than, not less than or equal to. The answer is B.
Note: When the sign is < or >, the line on the graph is dotted. If the sign is <= or >=, then the line on the graph is solid.
Answer:
-18F + 6g The exact value
AB is half AC therefore BC is 10 ft
Use Pythagorean theorem.
(8)^2 + (10)^2 = c^2. Square the left side
164 = c^2. Take the square root of both sides
√(164) = c
EC = √(164).
