Question

помогите пожалуйста дам 20ббалов

Answer 1

$1.y = - 2x + 3$

$y + 2x = 3$

$2x + y = 3$

____________________

$2.y = \frac{1}{2} x - 4$

$y - \frac{1}{2} x = - 4$

$2y - x = - 8$

$- x + 2y = - 8$

$x - 2y = 8$

____________________

$3.y = - 5$

$y + 5 = - 5 + 5$

$y + 5 = 0$

____________________

$4.x = 5$

$x - 5 = 5 - 5$

$x - 5 = 0$

____________________

$5.y = - 0.25x$

$y + 0.25x = 0$

$100y + 25x = 0$

$4y + x = 0$

$x + 4y = 0$

____________________

$6.y = |x|$

$0 = |x|$

$|x| = 0$

$x = 0$

____________________

$7.y = - | \frac{4}{x} |$

$0 = - | \frac{4}{x} |$

$0= - | \frac{4}{x} | .x = 0$

$0 = - \frac{ |4| }{ |x| }$

$0 = - \frac{4}{ |x| }$

$- \frac{4}{ |x| } = 0$

$\frac{4}{ |x| } = 0$

$4 = 0$
