Answer:
2±√13
Step-by-step explanation:
9/x=x-4
x² -4x - 9=0
x² -4x +4- 13=0
(x -2)²=13
x-2= ±√13
x= 2±√13
Answer:
I think it is triangular prisim
It can't be simplified, because
4. -5+8
5. 14x
6. 3+6x
7. -1x +-2
8. X
9. 15x+5
Reverse the table and observe
- For 1 month cost is 50
- For 2 months the cost is 100
See the pairs are (1,50) and (2,100) and so on
We know domain is set of x values and range is set of y values.
As there is no extra cost and the cost is 50$ per month cost depends upon the month means months are independent and cost is dependent , months are x and cost will be y then
The equation is
So here domain is all months
- {1,2,3,4,5,6,7,8,9,10,11,12}
