<span>Solve for d.
5+d>5−d                    Subtract 5 from both sides of this inequality:
                              
d>d                             There is no value for d that satisfies this inequality.
                                    No value can be greater than itself.

2p+3>2(p−3)          Multiply this out:    2p+3>2p-6
</span><span>                               Subtr 3 from both sides:  2p> 2p-9

           This is equivalent to 2p+9>2p.
            We could subtr. 2p from both sides:  0>-9.

            0> -9 is always true.  Thus, the given inequality has infinitely many solutions.

For the expression: ( a+b/b − a/a+b )÷( a+/a − b/a+b ) Find the domain. AND Prove that for all admissible values of a, the value
olya-2409 [2.1K]

Step-by-step explanation:

((a+b)/b − a/(a+b)) ÷ ((a+b)/a − b/(a+b))

To find the domain, remember that any denominators can't be 0.

b ≠ 0

a + b ≠ 0

a ≠ 0

(5/(a+1) − 3/(a−1) + 6/(a²−1)) × (a+1)/2

Distribute the a+1.

(5 − 3(a+1)/(a−1) + 6/(a−1)) / 2

Factor out 1/(a−1).

(5(a−1) − 3(a+1) + 6) / (2(a−1))

Simplify.

(5a − 5 − 3a − 3 + 6) / (2a−2)

(2a−2) / (2a−2)

How it is now is the answer. No common terms, can’t simplify, nothing. Just stays like that.
