Answer:
(x² -1) + y² = 9
Step-by-step explanation:
diameter=6 so radius means 6/2=3 (thus,radius²=3²=9)
centre (1 and midpoint of diameter is at y=0, so 1,0)
Answer:
x=3, y=-2. (3, -2).
Step-by-step explanation:
4x+2y=8
5x+3y=9
---------------
simplify 4x+2y=8 into 2x+y=4
-----------------
2x+y=4
5x+3y=9
----------------
y=4-2x
5x+3(4-2x)=9
5x+12-6x=9
-x=9-12
-x=-3
x=3
2(3)+y=4
6+y=4
y=4-6
y=-2
Answer: 2, 9, 14, 17, 19
Step-by-step explanation:
A box plot uses the values: minimum, maximum, median, first quartile and third quartile.
First sort the data from lowest to highest.
2,8,9,11,14,15,17,19,20
Thus, the minimum, or Data Point 1 is 2.
Then find the median.
8,9,11,14,15,17,19
9,11,14,15,17
11,14,15
14
Thus, the median, or Data Point 3 is 14.
For the 1st and 3rd quartile, simply, ignoring the median, find the median of the first and second half of the data.
8,9,11
9
Thus, the first quartile, or Data Point 2 is 9.
15,17,19
17.
Thus, the third quartile, or Data Point 4 is 17.
The maximum of the data, or Data Point 5 is 19.

Answer:
m= -5/4
Step-by-step explanation:
Slope can be translated to "rise over run". You go down 5 spaces and then move over 4 spaces.
