Hapa kuna hatua za kutafuta usawa tatu zinazokidhi eneo R:

Swali la 16: Unda usawa tatu zinazokidhi eneo R lililopewa.

Tutapata mlinganyo wa kila mstari (L1,L2,L3L_1, L_2, L_3) kisha tutabainisha ishara sahihi ya usawa kulingana na eneo R.

  1. Tafuta usawa kwa mstari L1L_1.

    Mstari L1L_1 unapita kwenye pointi (0,3)(0, 3) na (3,4)(3, 4).

    • Mteremko m1=4−33−0=13m_1 = \frac{4-3}{3-0} = \frac{1}{3}.
    • Y-intercept ni c1=3c_1 = 3.
    • Mlinganyo wa mstari ni y=13x+3y = \frac{1}{3}x + 3.
    • Eneo R liko juu ya mstari L1L_1. Ili kuthibitisha, chagua sehemu ndani ya R, kwa mfano (0,4)(0, 4): 4≥13(0)+3⇒4≥34 \ge \frac{1}{3}(0) + 3 \Rightarrow 4 \ge 3, ambayo ni kweli.
    • Kwa hivyo, usawa ni y≥13x+3y \ge \frac{1}{3}x + 3.
    • Kuzidisha kwa 3 ili kuondoa sehemu: 3y≥x+93y \ge x + 9.
    • Kupanga upya: x−3y≤−9x - 3y \le -9.
  2. Tafuta usawa kwa mstari L2L_2.

    Mstari L2L_2 unapita kwenye pointi (0,−1)(0, -1) na (2,1)(2, 1).

    • Mteremko m2=1−(−1)2−0=22=1m_2 = \frac{1 - (-1)}{2 - 0} = \frac{2}{2} = 1.
    • Y-intercept ni c2=−1c_2 = -1.
    • Mlinganyo wa mstari ni y=x−1y = x - 1.
    • Eneo R liko juu ya mstari L2L_2. Ili kuthibitisha, chagua sehemu ndani ya R, kwa mfano (0,4)(0, 4): 4≥0−1⇒4≥−14 \ge 0 - 1 \Rightarrow 4 \ge -1, ambayo ni kweli.
    • Kwa hivyo, usawa ni y≥x−1y \ge x - 1.
    • Kupanga upya: x−y≤1x - y \le 1.
  3. Tafuta usawa kwa mstari L3L_3.

    Mstari L3L_3 unapita kwenye pointi (0,5)(0, 5) na (5,3)(5, 3).

    • Mteremko m3=3−55−0=−25m_3 = \frac{3-5}{5-0} = \frac{-2}{5}.
    • Y-intercept ni c3=5c_3 = 5.
    • Mlinganyo wa mstari ni y=−25x+5y = -\frac{2}{5}x + 5.
    • Eneo R liko chini ya mstari L3L_3. Ili kuthibitisha, chagua sehemu ndani ya R, kwa mfano (0,4)(0, 4): 4≤−25(0)+5⇒4≤54 \le -\frac{2}{5}(0) + 5 \Rightarrow 4 \le 5, ambayo ni kweli.
    • Kwa hivyo, usawa ni y≤−25x+5y \le -\frac{2}{5}x + 5.
    • Kuzidisha kwa 5 ili kuondoa sehemu: 5y≤−2x+255y \le -2x + 25.
    • Kupanga upya: 2x+5y≤252x + 5y \le 25.

    Usawa tatu zinazokidhi eneo R ni:

    x−3y≤−9\boxed{x - 3y \le -9} x−y≤1\boxed{x - y \le 1} 2x+5y≤25\boxed{2x + 5y \le 25}
