Answer:
see below
Step-by-step explanation:
(7y +9 )(7y +9 ) or (7y+9)^2 you ALMOST had it...just missed the parentheses !
12x-3-3x=5-(x-8)
9x-3=5-(x-8)
9x-3=5-x+ 8
9x-3=13-x
9x=16- x
10x=16
X= 8/5
Answer:
Option C. x=-3
Step-by-step explanation:
we have
----> inequality A
solve for x
subtract 60 both sides
![-15x\leq 105-60](https://tex.z-dn.net/?f=-15x%5Cleq%20105-60)
![-15x\leq 45](https://tex.z-dn.net/?f=-15x%5Cleq%2045)
Divide by -15 both sides
Remember that when you multiply or divide both sides of an inequality by a negative number, you must reverse the inequality symbol
![x\geq -3](https://tex.z-dn.net/?f=x%5Cgeq%20-3)
The solution of the inequality A is the interval [-3,∞)
we have
----> inequality B
Solve for x
subtract 11 both sides
![14x\leq -31-11](https://tex.z-dn.net/?f=14x%5Cleq%20-31-11)
![14x\leq -42](https://tex.z-dn.net/?f=14x%5Cleq%20-42)
Divide by 14 both sides
![x\leq -3](https://tex.z-dn.net/?f=x%5Cleq%20-3)
The solution of the inequality B is the interval (-∞,-3]
The solution of the system is
(-∞,-3] ∩ [-3,∞) =-3
therefore
The solution is x=-3
