Answer:
The solution to the inequality 5.25 – b ≥ 6.5 is:
b ≤ -1.25
i.e. in interval form it is: (-∞,-1.25]
Step-by-step explanation:
We are given a inequality with a equality sign in terms of single variable b as follows:
5.25 – b ≥ 6.5
on subtracting both side by 5.25 we get:
-b ≥ 6.5-5.25
⇒ -b ≥ 1.25
on multiplying both side by -1 we get:
b ≤ -1.25 or in interval form it is: (-∞,-1.25]
( As we know that on multiplying by a negative number the sign of the inequality get interchanged )
