• Subtopic: Function notation and points \(f(x) = @ + 5\) — the expression appears incomplete or contains a typo, but it seems to involve a function with a constant or variable. The point of origin is given as (0, 6). The phrase "so entre n e g, a ce decílio até duncde" is unclear, possibly meaning "so between n and g, the decay until" — but the exact meaning is ambiguous due to transcription errors. • Subtopic: Calculating the slope Given points (1, 3), (5, ?), and (2, 3), the slope \(a\) is calculated as: \[ a = \frac{y_2 - y_1}{x_2 - x_1} = \frac{9 - 3}{2 - 0} = \frac{6}{2} = 3 \] The function is then expressed as: \[ f(n) = 3n + 5 \] • Subtopic: Parallel lines The functions are parallel if they have the same slope \(c\). For example, the sum of fractions: \[ \frac{7}{35} + \frac{12}{35} = \frac{21}{35} \] The value of \(y\) is calculated as: \[ y = 1 - \frac{21}{35} - \frac{21}{35} = 1 - \frac{42}{35} = 1 - \frac{6}{5} = \frac{5}{5} - \frac{6}{5} = -\frac{1}{5} \] (Note: The original expression had some inconsistencies; I adjusted the calculation for clarity.) • Subtopic: Inequalities and solving for \(x\) Given the inequality: \[ - \frac{7}{4} (x=1) \leq n - \fr...
