Given point doesn't satisfy the inequality

Step-by-step explanation:

In order to check, if an inequality is satisfied by the point or not the point is put in the inequality

Given inequality is:

5x-2y+1>0

Putting the point (-2,-1) in the inequality

5(-2)-2(-1)+1>0\\-10+3+1>0\\-10+4>0\\-6>0

As -6 cannot be greater than zero,

So,

To add 20.4 + 3.75 + 4.25, Crystal first added 3.75 and 4.25. Which property did Crystal use to add mentally?
evablogger [386]

Answer:

Associative Property of Addition

Step-by-step explanation:

From the list of given options, option A correctly answers the question and this is because

a + b + c = a + (b + c) --- (1)

or

a + b + c = (a + b) + c --- (2)

<em>The above illustrations only apply to Associative Property of Addition</em>

In Crystal's case:

20.4 + 3.75 + 4.25 = 20.4 + (3.75 + 4.25)

This can be compared to (1) above

Hence;

<em>Option A answers the question</em>
