Answer: Her score at the end of second stage = 30 points
Explanation:
Since we have given that
Danielle started with 10 points
Starting points = 10
In the first round ,
She lost = 20 points
( we will represent it as negative integer as she loses it) .
Now, her score becomes
In the second round,
She won = 20 points
(we will represent it as positive integer as she wins it ).
Now, her score becomes
Finally , her score becomes 30 points at the end of second round.
Answer:
y=1
Step-by-step explanation:
Start by plugging in -3 for x in the equation 2x+5y=-1 then solve for y.
2(-3)+5y=-1
-6+5y=-1 (add 6 to both sides)
5y=5 (divide both sides by 5)
y=1
It should be noted that a polygon is a flat two dimensional closed shape that has straight sides.
<h3>What is a polygon?</h3>
Your information is incomplete. Therefore, an overview of a polygon will be given.
A polygon simply means a plane figure which is described by a finite number of straight line segments that are connected in order to form a closed polygonal chain.
In this case, the length of a line segment can be measured by simply measuring the distance between the two endpoints.
It's simply the path between two points that has a definite length that can be measured.
Examples of polygon include triangles, quadrilateral, pentagon, etc.
