Hello!
To solve for x, we just multiply both sides by 20.
x≤ -4/5(20)
x≤-16
Therefore, our answer is 
I hope this helps!
Hey there! I'm happy to help!
A step function is a function that looks like stairs when you graph it. Normally the end of one line will be graphed as an open circle (less or greater than, not equal to) while the other end would be a closed circle. This allows for a new line of the function to start directly above it without it not being a function (an input cannot have two outputs)
The function f(x)=4 is just a horizontal line as it has a slope of 0 (there is no x on the right side of the equation), so this doesn't resemble a step function.
Have a wonderful day and keep learning! :D

<span>Two cylinders are shown. One is 216in^3 and one is 343in^3. Divide the smaller number (216) by the larger number (343). The answer is .629. That means that the smaller figure is approximately 63% the size of the larger figure.</span>
