The point ( -2,-1) satisfies which of the following inequalities?

Second Option

Step-by-step explanation:

Substitute the point in each of the given inequalities and verify if the inequality is met.

If the inequality is fulfilled then the point belongs to the region

For

-7 is not greater than zero. the inequality is not met

For

9 is greater than zero. So the point belongs to inequality

For

-2 is not greater than zero. the inequality is not met

For

-10 is not greater than zero. the inequality is not met

a4 - 3a2 - 1

step-by-step explanation:

step   1   :

equation at the end of step   1   :

  ((a4) -   3a2) -   1

step   2   :

trying to factor by splitting the middle term

2.1     factoring   a4-3a2-1  

the first term is,   a4   its coefficient is   1 .

the middle term is,   -3a2   its coefficient is   -3 .

the last term, "the constant", is   -1  

e

step-by-step explanation:

an equation by definition has to have two or more variables (x and 2 in this case)
