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)
-10,-3,-1 is your answer. So the first one
Answer:
$2.50
Step-by-step explanation:
x/5 = 1/2
x is equal to 1 because it is half of the total and 1 is half of 2.
5 is equal to 2 because it is the whole amount and 2 is also the whole amount.
If you then solve for x by doing
5(1) = 5
5/2 = 2.5
You get 2.5 or $2.50.
Answer:
$0.20*x + 55$
Step-by-step explanation:
x - is the number of text messages
Since x the number of text messages it means that to get the amount of money a person will spend will be: $0.20 * x
And to get the final equation we will just need to add $0.20 + x to $55 =
$0.20 * x + $55
