Question

Explain why x = 5 makes 4x − 1 ≤ 19 true but not 4x − 1 < 19

Answer 1

Answer:

4x-1<_ 19

Step-by-step explanation:

this is so because when we solve both left hand side of both equations we get 19 as the answer. In first equation the sign given is less than or equal to which means tht the lhs is less or equal to rhs

in second eq. lhs is only less than rhs.

so in first eq. 19is less or equal to 19 so it's true. but in the second eq. 19is less than 19..but actually 19is equal to 19, so the second eq is not true.
