Eula needs to buy binders that cost $4 each and notebooks that cost $2 each. She has $20. The graph of the inequality 4x + 2y ≤
Zolol [24]
She has to buy both binders and notebooks. So, you have to take into account that she has to have both. The closest you can get to $20 while still getting notebooks, is to buy 4 binders. 4 times 4 equals 16. So, she can get 4 binders and 2 notebooks, because then, 2 times 2 equals 4 and 16 plus 4 equals 20.

Which inequality is used to find the domain<br>​
Igoryamba
<h3>Answer: Choice D.  5x-5 \ge 0</h3>

This is because we want to avoid having negative numbers under the square root. So we make the radicand to be 0 or larger.

The +1 at the end doesn't affect the domain.

Identify the postulate illustrated by the statement: Line ST connects pointS and point T
Archy [21]

We have two points known to be ( S ) and ( T ). A line connects two points.

The minimum number of points that are required to form a straight line in a cartesian coordinate system are ( two ).

The minimum number of points that are required to form a plane in a cartesian coordinate system are ( three ) which will form two vectors i.e it requires two lines formed with a common point.

Two planes always intersect at exactly one point with direction normal to the two plane normal vectors.

Hence, the only possible postulate that relates two points is the formation of a line between two points; hence, the correct postulate for the given statement is:

\text{\textcolor{#FF7968}{Through any two points there is exactly one line}}
