Question

Write an inequality - 4 mutilplied by a number is less than or equal to - 16

Answer 1

start by giving the number a variable

number = x

now continue by writing the left part of the inequality multiplying by -4

`-4\cdot x`

remember that when writing <,> , they are always pointing to the smaller one.

Continue by completing the right side

`-4\cdot x\leq16`

Simplify by dividing by -4 on each side

`\begin{gathered} -4\cdot x\leq16 \\ -(4)/(-4)\cdot x\leq(16)/(-4) \\ x\leq-4 \end{gathered}`

answer:

In order to fulfill the inequality x must be less than or equal to -4-
