Answer:

Step-by-step explanation:

x=r cos \theta=7 cos150=7cos(180-30)=-7cos ~30=-\frac{7\sqrt{3} }{2} \\y=r~sin~\theta=7~sin ~150=7~sin~(180-30)=7~sin~30=\frac{7}{2} \\so ~coordinates ~are~(-\frac{7\sqrt{3}}{2} ,\frac{7}{2} )\\C

What is the justification for each step in solving the inequality?
Fed [463]

Step-by-step explanation:

3x+\frac{5}{8}\geq 4x-\frac{1}{2}

Subtract 5/8 on both sides

To subtract 5/8 we make the denominators same

3x\geq 4x-\frac{1*4}{2*4}-\frac{5}{8}

Addition or Subtraction property of order is used

3x\geq 4x-\frac{9}{8}

Subtract 4x on both sides

Addition or Subtraction property of order is used

-x\geq -\frac{9}{8}

Now divide both sides by -1

Multiplication or Division property of order is used

\frac{-x}{-1} \geq \frac{-\frac{9}{8}}{-1}

Multiplication or Division property of order is used

x\leq \frac{9}{8}
