four times a number x is at least -12
an inequality is ?
the solution is ?

Answer:

-16

Step-by-step explanation:

im just taking a guess.

x+4>-12

  -4   -4

---------------

4's cancel out and -12+-4=-16

Again this is just a guess.

The inequality is 4x ≥ -12 and the solution of this inequality is x ≥ -3.

Inequalities are the expressions having two sides connected with inequality symbols. Inequality symbols are <, >, ≤, ≥ and ≠. They may contain one or more variables and constants.

Inequalities which consist of one or more variables with the highest degree of the variables being 1 is called Linear inequalities.

Given that four times a number is at least -12.

Thus the inequality says that 4 multiplied with a number x, which is 4x has values -12 or greater than -12.

So the inequality is 4x ≥ -12.

Solving this,

4x ≥ -12

Dividing both sides by 4, we get,

4x/4 ≥ -12/4

x ≥ -3

Hence the inequality is 4x ≥ -12 and the solution is x ≥ -3.
