2x – 3 > -4x + 2<br> What is the solution to the inequality

bagirrra123 [75]

Answer:

$x>\frac{5}{6}$

Step-by-step explanation:

$2x-3>-4x+2$

Add 3 to both sides

$2x-3+3>-4x+2+3$

Simplify

$2x>-4x+5$

Add $4x$ to both sides

$2x+4x>-4x+5+4x$

Simplify

$6x>5$

Divide both sides by 6

$\frac{6x}{6} >\frac{5}{6}$

Simplify

$x>\frac{5}{6}$

Consider this quadratic equation. 2x2 − 1 = 3x + 4 Which equation correctly applies the quadratic formula?

Mariulka [41]

Answer:

$\frac{-(-3)+-\sqrt{(-3)^2-4(2)(-5)}}{2(2)}$

Step-by-step explanation:

Quadratic formula: $\frac{-b+-\sqrt{b^2-4ac} }{2a}$

$2x^2-1=3x+4\\\\2x^2-3x-5=0\\\\\\frac{-(-3)+-\sqrt{(-3)^2-4(2)(-5)}}{2(2)} \\\frac{3+-\sqrt{9+40} }{4}$

$x = \frac{3+-7}{4}$

Hope this helps and God bless!
