Which is not a correct way to represent the relation "the second number is 1 less than three times the first number"?
y = 1 - 3x
y = 3x + (-1)
y = -1 + 3x
y = 3x - 1

the first is not correct

y = 1 - 3x is not correct.

Step-by-step explanation:

One of the correct ways is 3x - 1.

First the number is multiplied by 3 then 1 is subtracted.

t = 3

step-by-step explanation:

answer: 5100 just subtract
