I think this may be multiplication so 5 times 10 equls50
Multiply top equation by -2, then add equations so b drops out....solve for a...plug in a to get b
domain of the problem is -5 and the range is 4
Step-by-step explanation:
a < (a + b)/2 < b
Solve the first inequality.
a < (a + b)/2
2a < a + b
a < b
Solve the second inequality.
(a + b)/2 < b
a + b < 2b
a < b
Both inequalities are true. Therefore, a < (a + b)/2 < b.
Yes your correct but thats not a question
