It seems some part of the text is missing, however, since we are talking about 'crests' I guess we are talking about waves.
In a wave, the distance between two consecutive crests corresponds to the wavelength of the wave. Therefore, the distance measured with the ruler is the wavelength of the wave.
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.
