Since |1-4x|>7 it can also be 1-4x<-7
so you get 1-4x>7 then get the x by its self -4x>7 then you make the x positive. multiply by -1 so you switch the sign 4x<7 divid by 4 and you get x<7/4 now you go on to the other equation 1-4x<-7 you get the x by itself and get -4x<-8 and multiply by -1 to get a positive number so you swith the sign 4x>8 so you didid by 4 and get x>2 so you get an interval notation of (-infinity,7/4) u (2,+infinity)
the |5x-1|<1 interval notation is (-2/5 ,0)
That isnt even a question is a mathematical statement
X is 0.1 because 0.1 x is 40 you move the decimal and make it a four because of multiplication
Distance = rate * time, so d = rt
therefore r = d/t
r = 0.5mi/0.75hr = 0.67 mi/hr
Answer:
$39.2
Step-by-step explanation:
The sale price will be 20% of $49 subtracted from $49
That’s
20% /100% x $49
0.2 x $49
$9.8
Sale price = $49 - $9.8
= $39.2
The sale price is $39.2
