Im kind of confused on what to do at this point.
how to solve -5x + 8 less than or greater to x - 4
Tutors, please sign in to answer this question.
-5x+8 vs x-4
first, lets separate the 2 functions.
f(x) can be replaced by y
x= 1 y=-3
the equations intercept at 2,-2
f(x)= x-4 is the greater equation if the linear equation is above the other equations plotted lines.
Are you confident that you read/wrote the question properly? The phrase "...less than or greater to..." reminds me of something I might find in a line of computer code as some sort of Boolean operator, for example Pascal's 'not equal to' operator '<>'.
