17. \( \alpha+4=\beta-1=\gamma-3=\varphi+6 \) болса, онда \( \alpha, \beta, \gamma, \varphi \) натурал сандарының кайсысы ен үлкен болады? A) \( \alpha \) B \( \gamma \) C) \( \beta \) D) анықталмайды E) \( \varphi \)

18. \( \begin{aligned} y & =x-5 \\ y & =-2 x-5\end{aligned} \)

D) A student claimed that the largest integer of \( k \) for which the graph \( y=2 x^{2}-3 x+k-1 \) meets the \( x \)-axis is 2 . Verify this statement.

Risolvi le seques \( \frac{-x^{2}+7 x-12}{2 x^{2}-7 x+3} \geqslant 0 \)

Find the slope and the \( y \)-intercept of the graph of the equation. \[ 8 x+9 y=36 \] slope \( y \)-intercept \( \quad(x, y)=(\square) \)

3.1.2 The number pattern is quadratic and \( T_{4}=2+5 y \). 3.2 In a linear number pattern, the \( 19^{\text {th }} \) term is 40 and the \( 7^{\text {th }} \) term is 16 . Thus, determine the first two terms.
