The solution of a+b>−4 is a>−9. What is the value of b?

When the solution of , then the value of b is 5

Given :

the solution of  inequality  

We need to find the value of b

Subtract b on both sides and solve for 'a'

we know that the solution is a>-9

Lets equation both the solutions

Add 4 on both sides

So, the value of 'b' is 5

b=5

Step-by-step explanation:

hello :

a+b>−4 means :  a+b-b>−4 -b

a>−4 -b    so : -4-b = -9  

multiply by : -1   : 4+b=9

4+b-4 = 9-4

b=5

the answer is a) y= 2 csc [0.5 (x+pi/2)]-1
