Answer:
(1/5x)-6<99
not < the one with the line under it
Step-by-step explanation:
Answer: x < -4 and -4 > x
x < -4 would be one of the two options.
This means that any number less than -4 is a solution.
This is shown by drawing an open dot on -4 and then
drawing an arrow to the left shows all answer less tan 4.
-4 > x would be our second option.
We can change it to say x < -4.
All I did was changed the order of numbers and switched the sign.
So x < -4 is the same as the first option.
y=-4x+7
the -4 is the slope and the 7 is the y-intercept
