Math Problem Statement

What are the solutions of -9/8a + 1 < 6?

Solution

The problem in the image asks: "What are the solutions of 98a+1<6-\frac{9}{8}a + 1 < 6?" with multiple choices provided for the possible solution ranges of aa.

Let's solve this inequality:

  1. Start with the inequality: 98a+1<6-\frac{9}{8}a + 1 < 6

  2. Subtract 1 from both sides to isolate the term with aa: 98a<5-\frac{9}{8}a < 5

  3. Multiply both sides of the inequality by 89-\frac{8}{9} to solve for aa, remembering to reverse the inequality sign when multiplying by a negative number: a>8×59=409a > -\frac{8 \times 5}{9} = -\frac{40}{9}

Thus, the solution is: a>409or approximatelya>4.44a > -\frac{40}{9} \quad \text{or approximately} \quad a > -4.44

Looking at the answer choices:

  • The correct inequality is closest to H. a>63a > -63, though it seems the answer choices are off by magnitude.
