The only point outside of the line is (2, 0)
In order to find if a point is outside, inside or on the line, you simply have to put the number into the equation. If the result is both sides are equal, then it is on the line. If the left side is bigger than the right side, then it is outside of the line. If the right side is bigger than the left, then it is inside of the line. So lets plug in and see where (2, 0) falls.
(x - 2)^2 + (y + 3)^2 = 4
(2 - 2)^2 + (0 + 3)^2 = 4
0^2 + 3^2 = 4
0 + 9 = 4
9 = 4
Since the left side is bigger than the right, we know it is outside of the line.
Answer:
30
Step-by-step explanation:
Substitute X with 7 since X=7 so 2(7+8). Follow order of operations and 7+8=15 and the multiply 15 by 2 to get your final answer 30.
Answer:
82 degrees
Step-by-step explanation:
It took 3 hours for it to go from 78 to 72.
Which is a rate of -2 degrees per hour
We want to know what the temperature was two hours before it was 78 degrees so we'd do 78 - (-2) which is 82
