Having trouble w graphing :(
1 answer:
6x/6=x>/= (=) 11/6
x=11/6 or about 1.8
the first important notation to remember when graphing inequalities is that the graph is going to face the way the inequality sign is pointing.
in this case, the sign is pointing right. now the second thing to remember is that an inequality sign with a line underneath it means that it is greater/equal to so the graph in which we fill will have be a closed circle
1) start the ray at ~1.8 and fill in the circle at the end of the ray then extend to its endpoint
that's all. you're graph now reads x is greater or equal to 11/6

Lets say that the two unknown integers are 
and 
.
We know the following things about and :
And, we want to find
.
To solve this, we'll use the expansion of the squared of the sum of any two inegers; this is expressed as:
So, given what we know about the unknown integers, the previous can be written as:
We can easily solve for:
The answer is 168.
Another approach to solve the problem is, from the two starting equations, compute the values of and , which are 12 and 14, and directly compute their product; however, the approach described is more elegant.
