Inequalities help us to compare two unequal expressions. The value of x must be less than -19/13.
<h3>What are inequalities?</h3>
Inequalities help us to compare two unequal expressions. Also, it helps us to compare the non-equal expressions so that an equation can be formed. It is mostly denoted by the symbol <, >, ≤, and ≥.
The given inequalities can be simplified as,
1.)
−9x+2>18
−9x>18-2
−9x>16
x < -16/9
Thus, the value of x must be less than -16/9.
2.)
13x+15≤−4
13x ≤ -19
x ≤ -19/13
Thus, the value of x must be less than -19/13.
For the given condition −9x+2>18 OR 13x+15≤−4, the value of x must follow any one of the inequality. Hence, the value of x must be less than -19/13.

Since x can be any value as long as the denominator equals 0 (it doesn't matter if it's positive or negative), we have to figure out when x^2=0, which is when x=0. Therefore, the domain is (-inf, 0) U (0, inf)
So
x- quarters
y - dimes
z- nickels
The system of equations would be
x+10=y
z+5=x
x+y+z= 4.75
