Answer:
Inequality to represent given data is y ≥ 5.
No, y = 4 is not a solution, since 4 is not a value that falls within the domain of the solutions for the inequality.
Step-by-step explanation:
Enter an inequality that represents the phrase the sum of 1 and y is greater than or equal to 6. The inequality is y = 4 a solution.
i) therefore y + 1 ≥ 6
ii) therefore y ≥ 5
iii) No, y = 4 is not a solution, since 4 is not a value that falls within the domain of the solutions for the inequality.
Answer:
3, 6, 4, 5
Step-by-step explanation:
First of all we have to multiply 2 by 2x and -9 and we obtain
4x -18 ≤ 6
now we have to move -18 on the right side of the minor or equal and change its sign
4x ≤ 6 + 18
now we have to added up 6 and 18
4x ≤ 24
At least we have to divide the the two members by 4
x ≤ 6
We have to find the numbers ≤ 6
so the answer is : 3, 6, 4, 5
