Which of the following equations do not represent a proportional relationship? y = 4/3x y = 2x - 1 y = x y = 1.4x

Answers

Answer:

y = 2x - 1

Step-by-step explanation:

y = 2x - 1 wouldn't be a proportional relationship. You can tell because any equation with addition or subtraction is not going to be proportional.

Answer:

y=2x-1

Step-by-step explanation:

notice how the second option, y=2x-1 is the only option that has a constant. All other options only have a coefficient on the x term. This makes it perfectly proportional by the factor of the coefficient.

The answer would be 1 13/24

You want to do

But you have to have the same denominators so you (x) 1/8 by 3 and 2/3 by 8 to get

8 16/24
7 3/24

Then you just subtract 16 and 3 to get 13 and subtract 8 and 7 to get 1 so the answer would be 1 13/24

So start out with -5 then subtract -2 you get -3 then subtract 12-3 and get nine. That’s your answer 9. Hope this helps.
Since the slope is equal to -5 you can already get the beginning of the equation being y=mx+b; M=-5, now to find b you need to plug in your numbers: 12=-5(-2)+b then you get 12=10+b. subtract the 10 to find that b=2 then plug in all the numbers to find the answer y=-5x+2

Answer:

   

Step-by-step explanation:

Nico and Lorena used different methods to determine the product of three fractions.

Nico’s Method
Lorena’s Method
(2) (one-sixth) (Negative four-fifths) = (StartFraction 2 over 1 EndFraction) (one-sixth) (negative four-fifths) = StartFraction (2) (1) (negative 4) over (1) (6) (5) EndFraction = Negative StartFraction 8 over 30 EndFraction = Negative StartFraction 4 over 15 EndFraction
(2) (one-sixth) (Negative four-fifths) = (StartFraction 2 over 1 EndFraction) (one-sixth) (negative four-fifths) = StartFraction (2) (1) (negative 4) over (1) (6) (5) EndFraction = Negative StartFraction 8 over Negative 30 EndFraction = StartFraction 4 over 15 EndFraction

Whose solution is correct and why?
Nico is correct because he knew that Negative four-fifths = StartFraction negative 4 over negative 5 EndFraction.
Nico is correct because he knew that Negative four-fifths = StartFraction negative 4 over 5 EndFraction.
Lorena is correct because she knew that Negative four-fifths = StartFraction negative 4 over 5 EndFraction
