Answer: (x - 5)^2 + (y - 7)^2 = 50
Step-by-step explanation:
The general equation for a circle is (x - a)^2 + (y - b)^2 = r^2 where (a, b) is the centre
Use Pythagoras to find r^2
r^2 = (5 - -2)^2 + (7 - 8)^2
= 7^2 + (-1)^2
= 50
So the circle is (x - 5)^2 + (y - 7)^2 = 50
Answer:
3(-x+2)(x+2)
Step-by-step explanation:
1.-3x^2+12
2.-3x^2+2^2x3
3.3(- 3x^2/3 +2^2 x3/3)
4.3(-x+2)(x+2)
The median of the following data values is 100
7. (1,2),(0,-1)
slope = (-1 - 2) / (0 - 1) = -3/-1 = 3 <==
8. (-1,0),(1,-1)
slope = (-1 - 0) / (1 - (-1) = -1 / 2 <==
Answer:
2.) (5 - 5)x
Step-by-step explanation:
1. Multiply (5-5) with x
2. Answer is 5x - 5x, so this is not equivalent
