We are given: \(h + 9.7 = -9.7\)
Subtract 9.7 from both sides: \(h + 9.7 = -9.7-9.7\)
Let a and b be positive numbers such that \(a < b\). State whether the absolute value equation has no solution, two negative solutions, two positive solutions, or one positive and one negative solution.
\(|x − b| = -a\)
two negative solutions
two positive solutions
one positive and one negative solution
Let a, b and c be a real numbers such that \(a>0, b<0\) and \(c<0\). Find the sign of each expression.
Express the number in terms of i.
