Question

the value of -5x +6 is____ when x is 4

Answer 1

on questions like these, the problem tells you that x=4

what you should do is plug in the 4 where x is in the equation, since x is equivalent to 4

Ex: -5(4)=6

Does that make sense? @msbass ?

Answer 2

so it becomes -5 x 4 +6?

Answer 3

thats right :) and then you would solve using order of operations

Answer 4

26?

Answer 5

No, its negative, one positive and one negative = negative so its -20 + 6

Answer 6

well..think about it this way… what is -5 * 4?

Answer 7

-14

Answer 8

as @tHe_FiZiCx99 has just explained… -5*4=20… so -14 is correct

Answer 9

so if the x is -4 it becomes a positive?

Answer 10

yeah :)

Answer 13

They either both have to be positive or both negative to be positive,

One positive and a negative = negative
positive and positive = positive
negative and a negative = positive
