Answer:
[-2,7] is the solution of inequality .
Step-by-step explanation:
Given : inequality 2 | 5 - 2x | - 3 ≤ 15
To find: solution of inequality.
Solution : We have given that 2 | 5 - 2x | - 3 ≤ 15
.
On adding 3 both sides:
2 | 5 - 2x | - 3+3 ≤ 15
+3
2 | 5 - 2x | ≤ 18.
ON dividing both side by 2 and simplify
| 5 - 2x | ≤ 9.
On applying absolute rule, if | u | ≤ a,a> then -a ≤ u≤ a
-9≤5 - 2x ≤ 9.
5 - 2x ≤ 9 , 5 - 2x ≤ -9.
- 2x ≤ 9-5
- 2x ≤ 4
On dividing by -2
x ≥ -2.
For 5 - 2x ≤ -9.
- 2x ≤ -9-5
- 2x ≤ -14
On dividing by -2
x ≤ 7
Therefore , [-2,7] is the solution of inequality .
Your answer is B) 12y = 4
You can find this by first rearranging the equation x + 3y = -2 to the form ‘x =‘:
x = -2 - 3y.
Then you can substitute this into the second equation, 2x - 6y = -8, and expand and solve:
2(-2 - 3y) - 6y = -8
-4 - 6y - 6y = -8
-12y = -4
Now because we know that -12y = -4, this is equivalent to 12y = 4, which is option B.
I hope this helps! Let me know if you have any questions :)
