PERIOD: All Periods

2. What is the solution to the linear inequality for \(x\)?

\(-3(x - 6)\)

>

\(2x - 2\)

From NYS Regents Examination • August 2023, Problem #10

Step 1: Distribute & write terms in the boxes and circles: -3(x - 6) = -3x + 18

Circle Team (Move Right • Change Sign!)

X-BOX

\(-3x\)

CIRCLE

\(+18\)

>

X-Box Team (Move Left • Change Sign!)

X-BOX

\(2x\)

CIRCLE

\(-2\)

> "Cross the line... change the sign!" >

+ MOVED X-BOX

\(-2x\)

>

+ MOVED CIRCLE

\(-18\)

Combined X-Box:

\(-5x\)

>

Combined Circle:

\(-20\)

!

Final Step: Divide by Negative Coefficient!

Divide both sides by the coefficient! Because you divide by a NEGATIVE NUMBER: YOU MUST FLIP THE INEQUALITY SYMBOL FROM > TO < ! Work: \(\frac{-5x}{-5} < \frac{-20}{-5} \implies x < 4\)

Final Solution: \(x\)

<

\(4\)

NUMBER OF SOLUTIONS: Exactly One ✓ Infinitely Many (\(x < 4\))

SELECT THE MATCHING REGENTS CHOICE: Choice (2) is correct

(1) \(x > 4\)

✓ (2) \(x < 4\)

(3) \(x > -16\)

(4) \(x < -16\)

NUMBER LINE PLOT:

✓ Open Circle at \(4\) (Shaded Ray Left)

-2 0 2 4 6 8

TI-Nspire Check • Test a Value in the Shaded Ray!

1. Store a test solution: 0 → x • 2. Type: -3(x - 6) > 2x - 2 → ENTER → "true"!

Paso Final: ¡Divide entre el Coeficiente Negativo!

Divide ambos lados entre ¡el coeficiente! Porque divides entre un NÚMERO NEGATIVO: ¡DEBES INVERTIR EL SÍMBOLO DE DESIGUALDAD DE > A < !

Solución Final: \(x\)

NÚMERO DE SOLUCIONES: Exactamente Una Infinitas Soluciones (\(x < 4\))

SELECCIONA LA OPCIÓN CORRESPONDIENTE DE REGENTS: Encierra en un círculo una opción

(1) \(x > 4\)

(2) \(x < 4\)

(3) \(x > -16\)

(4) \(x < -16\)
