Answer:

y = 1.6x - 2

Step-by-step explanation:

2.4x - 1.5y = 3

→2.4x - 1.5y + -2.4x = 3 + -2.4x ( first add -2.4x on both sides) = -1.5y = -2.4x + 3

→ $\frac{-1.5}{-1.5}$ = $\frac{-2,4x + 3}{-1.5}$ ( divide both sides by egative 1.5)

→ y = 1.6x -2 or -2 + 1.6

Solve This Using The Quadratic Formula: 3x^2+9x-6=0

aivan3 [116]

<h3>Therefore either $x = \frac{-3+\sqrt{17}}{2}$ or, $x = \frac{-3-\sqrt{17}}{2}$ </h3>

Step-by-step explanation:

$3x^2 +9x -6=0$ $x = \frac{-b\pm\sqrt{b^2- 4ac} }{2a}$

$\Leftrightarrow x = \frac{-9\pm\sqrt{9^2- 4.3(-6)} }{2.3}$ here a = 3 ,b = 9 and c= -6

$\Leftrightarrow x = \frac{-9\pm\sqrt{153} }{6}$

$\Leftrightarrow x = \frac{3(-3\pm\sqrt{17}) }{6}$

$\Leftrightarrow x = \frac{-3\pm\sqrt{17}}{2}$

Therefore either $x = \frac{-3+\sqrt{17}}{2}$ or, $x = \frac{-3-\sqrt{17}}{2}$
