sin30 =  \frac{o}{h}  \\ sin30 =  \frac{5}{x}  \\ x =  \frac{5}{0.5}  \\ x = 10

{10}^{2}  +  {10}^{2}   =  {y}^{2}  \\ 100 + 100 =  {y}^{2}  \\ 200 =  {y}^{2}  \\  \sqrt{200}  = y \\ 14.14 = y\\

What is the solution to the inequality? -2/3(2x - 1/2) ≤ 1/5x - 1 Express your answer in interval notation.
almond37 [142]

ANSWER


-\frac{2}{3}(2x-\frac{1}{2})\le \frac{1}{5}x-1


Multiply through by LCM of 15


(15) \times -\frac{2}{3}(2x-\frac{1}{2})\le 15(\frac{1}{5}x-1)





-10(2x-\frac{1}{2})\le 3x-15



Expand brackets to obtain,



-20x+5\le 3x-15



Group like terms



15+5\le 20x+3x




20\le 23x


\frac{20}{23}\le x




x\ge \frac{20}{23}


In interval form it is written as


[\frac{20}{23}, \infty)
