y + 5 is equal to or greater than 7
Is y less than or greater than 12?
Please check, and help correct.
y+5 >= 7
subtract 5 from both sides:
y >= 2
so, y could be less than 12 or greater than 12
for example,
y=3
y+5 = 10 >= 7
y=20
y+5 = 25 >= 7
what the heck is the answer then?
To check whether y is less than or greater than 12, we first need to solve the inequality y + 5 ≥ 7.
Subtract 5 from both sides of the inequality to isolate y:
y + 5 - 5 ≥ 7 - 5
y ≥ 2
So, y is greater than or equal to 2.
To determine whether y is less than or greater than 12, we compare y to 12 using the information we obtained: y ≥ 2.
Since y is greater than or equal to 2, it is also greater than or equal to any number less than 2. Therefore, y is both less than and greater than 12.
In mathematical terms, we can write:
y < 12 and y ≥ 2
