3x^2 + 3y^2 = 75
Dividing through by 3 we get
x^2 + y^2 = 25
The center is at (0,0) answer
So basically what you need here first is to find the disciple and reverse it, then you will have your answer.
Answer:
(x-6) (2x+1)
Step-by-step explanation:
1) move everything over to the left side, so subtract 11x and 6.
2x^2 -11x - 6 = 0
2)multiply 2(a term) with -6 (c term)
x^2 -11x -12
3) factor and find what multiples to -12 and adds up to -11. in this case its -12 and positive 1
(x-12) (x+1)
4) divide -12 and 1 by the original a term (2)
(x-6) (x+1/2)
5) move the denominator of 2 over to the x.
(x-6) (2x+1)
Answer:
-7.2
Step-by-step explanation:
Since -3.2 is the first number, this will be the starting point in the number line.
Since we are subtracting, we are going to go 4 units to the left.
-3.2 - 4 = -7.2
Best of Luck!
