My assignmend is telling me to use the display command to display the phrase "The first random variable is" and the x value (calculated earlier in the script) on the same line. The result should be:
The first random variable is 4
Not:
The first random variable is
4
Heres the code (don't worry about the y value)
x=ceil(5*rand(1));
y=floor(99*rand(1));
disp("The first number is ")
disp(x)

Homework I assume.
You have to do it with one disp() statement, because disp() automatically adds a newline after the output

Or use fprintf() like I show in my Answer below.

Use fprintf():
fprintf('The first random variable is %d.\n', x);

See Append Text to Strings before you try my code.
>> "abc"+"def"
ans =
"abcdef"
>>
and your example
>> x = 17;
>> disp( "The first number is " + num2str(x) )
The first number is 17
it's even possible to add the numerical x to the string.
>> disp("The first number is " + x )
The first number is 17
The doc on plus, + Addition says
If one input is a string array, then the other input can be a numeric, logical, character, string, or cell array.
>> "true is displayed as "+true
ans =
"true is displayed as true"

Would this be considered a character array or string? I need to output text without using either...
disp("The original number was "+integer+" and the flipped number is "+flipped)

Text is either a character array, if single quotes were used to build it, or a string, if double quotes were used to build it.
Why do you need to output text without using either a character array or string? That seems really really weird. Regardless, you can't, since text has to be either one or the other. It can't be "neither".

If the point is that the output must not have the quotation marks, then disp() should work for that purpose.
But I suspect that the restriction is hinting that you should be using fprintf.

This image is from the assignment. Yeah, it seems weird to me too. But I also may not be understanding what it means fully.
