  1. Matematika 7 Linearna funkcija i jednadžba pravaca

  2. Odredi nul-točku linearnih funkcija i je li linearna funkcija rastuća ili padajuća. • f(x) = 7.2x - 15 • f(x) = -18.4x + 13.1 • f(x) = 5.4x - 5 • f(x) = 8.8x - 8 • f(x) = -15.6x + 18.8 • f(x) = -0.8x - 0.9 • f(x) = 8.6x + 8.6 Riješi zadatke!

  3. Odredikoeficijentsmjerazadanihpravaca. • 18x + 19y - 7 = 0 • 12x + y - 17.8 = 0 • 19x + 18y - 5 = 0 • x + 18y - 7 = 0 • x + 7y - 5 = 0 • 15x + 19y - 3 = 0 Riješi zadatke!

  4. Pronađi jednadžbu pravca koji je usporedan sa pravcem: • 1x + 14y - 19 = 0 i prolazi točkom T(-7, -7) • 14x + 10y - 11 = 0 i prolazi točkom T(-9, -5) • -0.8x - y = 17 i prolazi točkom T(-4, 6) • -11.6x - y = 5 i prolazi točkom T(-9, 3) • -8.7x + 13y + 9.4 = 0 i prolazi točkom T(3, -3) • -12.1x - y = 10 i prolazi točkom T(1, -8) • 0.3x - 18y - 2 = 0 i prolazi točkom T(-6, -9) Riješi zadatke!

  5. Odredi koordinate sjecišta pravaca: • 9.4x - 4y + 2 = 0 i -4x - 3y + -6 = 0 • y = -1x - 8.7 i y = 4x + 6.2 • 6.1x - 7y + 5 = 0 i -4x - 11y + -3 = 0 • y = -5x - 3.8 i y = 2x + 6.4 • y = -3x - 1.1 i y = 7x + 2 • y = -10x - 3 i y = -11x - 8 • 8.9x - 8y + 10 = 0 i -10x - 4y + -9 = 0 Riješi zadatke!
