- Simplify the algebraic expressions in Problems 1–14 by combining similar terms. 5x - 2 - 7x + 4 - x - 1arrow_forwardIn Problems 55–74, solve each equation in the complex number systemarrow_forwardSimplify the algebraic expressions in Problems 1–14 by combining similar terms. 4n - 9n - narrow_forward
- In Problems 49–54, perform the indicated operations, and express your answer in the form a + biarrow_forwardIn Problems 37–44, expressions that occur in calculus are given. Reduce each expression to lowest terms.arrow_forwardIn Problems 1–8, find the exact value of each expression. Do not use a calculator.arrow_forward
- Subtract 1.2a“ – 0.7a from the sum of 0.6 a4 + 1.5a and 0.4 a4 - 1.1a First, we will translate the words of the problem into mathematical symbols. Then we will perform the indicated operations. The words of the problem contain the key phrases subtract from and sum. Since 1.2a4 – 0.7a is to be subtracted from the sum, the order must be reversed when we translate to mathematical symbols. Subtract 1.2a4 0.7a from the sum of 0.6a + 1.5a and 0.4a4 1.1a. [(0.6 a4 + 1.5a) + (0.4 at – 1.1a) ] - (1.2a* – 0.7a) Use brackets [ ] to enclose the sum. Next, we remove the grouping symbols to obtain 0.6 a4 + 1.5a + 0.4 at – 1.1a -1.2a4 + 0.7a Change the sign of each term within (1.2a4 - 0.7a) and drop the parentheses. at+ a Combine like terms. %D Subtract -0.6q? – 0.6q from the sum of 0.1q? - 0.6q and 0.3q² + 0.1q.arrow_forwardIn Problems 49–60, solve each inequality algebraically.arrow_forwardShow that the equation x4+yt = 100 has no solution when each of x and y is a positive integer.arrow_forward
