Answer 1

Answer is 6.5.


the equation that they gave you was
y = 3x - 1

below that they said that x = 2.5


what u would do is put the 2.5 where the x was bc that’s the x’s value. and what 3x means is basically 3 times x. what ever x is u multiply by 3. so since x is 2.5 u times it by 3.

3 • 2.5 = 7.5.

and then finish the rest of the equation which is to subtract 1.

7.5 - 1 = 6.5

hope this helped
