Reflection across the y-axis on a coordinate plane.
What is the short definition of a coordinate plane?
Two number lines combine to produce the coordinate plane, a two-dimensional surface. The x-axis is a single horizontal number line. The y-axis is a vertical number line, which is the other number line. A place known as the origin is where the two axes collide. The coordinate plane allows us to graph points, lines, and more.
What is reflaction of coordinate plane?
Transformation is the process of making each point in a shape appear at the same distance on the other side of a specified line.
The term "line of reflection" refers to introspection with relation to that line. A line is crossed to flip the image.

You have to divide the 5 and 5x by 5 add your variables together in alpha order=1
The answer is 54 square units.
let the vertex in quadrant I be (x,y)
<span>then the vertex in quadratnt II is (-x,y) </span>
<span>base of the rectangle = 2x </span>
<span>height of the rectangle = y </span>
<span>Area = xy </span>
<span>= x(27 - x</span>²<span>) </span>
<span>= -x</span>³<span> + 27x </span>
<span>d(area)/dx = 3x</span>²<span> - 27 </span><span>= 0 for a maximum of area </span>
<span>3x</span>²<span> = 3 x 3</span>² = <span>27 </span>
<span>x</span>²<span> = 9 </span>
<span>x = ±3 </span>
<span>y = 27-9 = 18 </span>
So, the largest area = 3 x 18 = 54 square units
You could cross multiply I believe and see if they are equivalent. There is another way to do it. I’m not sure. I guess you could plug the numerator into a calculator and then divide by the denominator by both. You could then get decimals and see which is bigger.
Each cheeseburger is $4 and each cup of lemonade is $1.
So 1 cheeseburger and 2 cups of lemonade would cost $6.
