Solution Verification Fbd455
1. Let's verify the solution to the inequality $14x + 2 > 26x + 46$.
2. Start by subtracting $26x$ and $46$ from both sides:
$$14x + 2 - 26x - 46 > 0$$
which simplifies to
$$-12x - 44 > 0$$
3. Add $44$ to both sides:
$$-12x > 44$$
4. Divide both sides by $-12$. Remember, dividing by a negative number reverses the inequality:
$$x < -\frac{44}{12} = -\frac{11}{3} \approx -3.67$$
5. The original solution $x \leq 4$ is incorrect. The correct solution is $x < -\frac{11}{3}$.
6. For the taxi problem: Carissa has $25$ total, with a flat fee of $5$ and $2.50$ per km.
7. Subtract the flat fee:
$$25 - 5 = 20$$
8. Divide by the per km charge:
$$\frac{20}{2.5} = 8$$
9. So, Carissa can travel up to $8$ kilometers.
10. The algebraic expression for the taxi fare is:
$$5 + 2.5p$$
where $p$ is the distance in kilometers.
11. The solution and explanation for Khiara saving money is correct.
12. The linear pattern with equation $y = -2x + 14$ matches the table values and the calculation for $x = -10$ yielding $y = 34$ is correct.
13. The algebraic expressions and calculations for the coach bus company cost are correct.
14. Summary: The only incorrect part is the inequality solution; it should be $x < -\frac{11}{3}$, not $x \leq 4$. All other answers and explanations are correct.
