Can someone me with this question ?

When can u say there is no solution for a system of linear inequalities? explain your answer and show with a system and graph

The length of a rectangle is x times the square root of 100. the width is one-half y more than three-halves x. given that the area of the rectangle is 125 cm2, which equation could represent the rectangle in terms of x and y? a) 5xy − 15x = 125 b) 5xy + 15x = 125 c) 15x2 − 5xy = 125 d) 15x2 + 5xy = 125

What statement is true? 2x^2-9x+2=-1
