Answer:
15 ; 4 ; 10 ; 6 ; same ; 2.5
Step-by-step explanation:
1) 15 because the initial height is a constant, so it can‘t be multiply for a variable
2) 4. The x represent the weeks and the growing of the plant depends on the weeks
3) 10 because the initial height is a constant
4) 6. The x represent the weeks and the growing of the plant depends on the weeks
5) same
6) we have to solve the equation
- add at the two members -6x
4x + 15 -6x = 6x + 10 -6x
-2x + 15 = 10
- add at the two members -15
-2x + 15 - 15 = 10 - 15
-2x = -5
- divide the two members by -2
x = 5/2
x = 2,5
