No it is not a function because an x value is used twice. in order for it to be a function, no x’s can be used twice/repeated.
hope this helps (:
replace x with 5.75 feet
y = 12(5.75)
12 * 5.75 = 69
the desk is 69 inches long
Solution
34x-12=12
or, 34x=12+12
or, 34x=36
or, x=36÷34
OR, x=1.05 is your answer
