Explanation / Answer

1) -1/2 <=-1/4 x - 5 < 2

this is linear inequality

2) 2x^2 - 6x = 5

theis is quadratic equation

3) 50x^3 - 25x^2 - 2x + 1 = 0

this is a polynomial equation

4) -5x ( x - 3)^2 / ( 2+x) <= 0

this is a rational inequality

5) 4th root ( m + 4) - 5 = -2

this is a radical equation

6) -5 < y and -3y + 4 >= 7

this is a compound inequality

7) | 5t - 4| + 2 = 7

this is a absolute value equation

8) absolute value equation

9) quadratic equation

10) rational equation
