I think you have to multiply across.
Answer:
x>=-1, B
Step-by-step explanation:
1. distribute 2 to get 7+x <= 2x+6+2
2. simplify to get 7+x <= 2x+8
3. subtract 7 on both sides to get x<=2x+1
4. subtract x on both sides to get 0 <= x+1
5. subtract 1 on both sides to get x >= -1
B fits this description
Answer:
After about 12 months both Caitlyn and Santos will have the same balance of 150 dollars in their bank account.
Step-by-step explanation:
Caitlyn's saving: -5x+210
Santos' saving: 5x+90
To know when the total amount in their bank account is the same you would need to make these linear equations equal to one another.
-5x+210 = 5x+90
(Add 5x on both sides)
210=10x+90
(Subtract 90 from both sides)
120=10x
(Simplify)
x=12
After about 12 months their total savings should be the same. To check what their balance will be plug the x value of 12 into both of these equations. This should give 150 as your answer for both equations.
Y=-7x-5
9=-7(-2)-5
9=14-5
9=9
