The distance between any 2 points P(a,b) and
Q(c,d) in the coordinate plane, is given by the formula:<span>

Using this formula we calculate the distances |PA|, |PB|, |PC|, |PD| and |PE| and compare to 5.





Answer: B and D
Answer: C. (0, -3)
Step-by-step explanation:
You don't even need to find the function, just mentally graph every point in the options on the graph.
- If it land in the white area, it's not a solution.
- If it land in the blue area or on the line, it's a solution.
<em>The line is not dotted, showing that the inequality is probably either ≥ or ≤, so points on the line do count as solution.</em>
The answer is 35/10 and 6/10
Answer:
The lodge is 21 feet tall.
Step-by-step explanation:
Ski Lodge:
object/shadow
x/3
Ski Pole:
object/shadow
3.5/0.5
Solve for x:
x/3 = 3.5/0.5
0.5x = 10.5
x = 21
You can find any ordered pair in which the y coordinate is 4 times the x coordinate.
For example, an ordered pair could be (2,8) or (5,20)
