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

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

Answer:

Step-by-step explanation:

$\text{LHS}=\frac{1}{\sec \theta-\tan \theta}\\=\frac{\sec \theta+\tan \theta}{(\sec \theta-\tan \theta)(\sec \theta+\tan \theta)}\\=\frac{\sec \theta+\tan \theta}{\sec^{2} \theta-\tan^{2} \theta}\\=\frac{\sec \theta+\tan \theta}{1}\\=\sec \theta+\tan \theta\\=\text{RHS}$
