Uh... what is Vivoedge? I don't have one as you can probably tell by my question.

Reflection across the y-axis is exactly like relfection across the x-axis except in this one you change the x point

(x,y) -> (-x,y).

Mathematically, reflection across the x-axis means a point (x,y) undergoes a change to the y point, (x,-y).

Examples:

Point α is (4,6), find the relfection across the x-axis of Point α... 

The reflection of Point α across the x-axis is (4,-6)

Point γ is (-420, -1337), find the reflection across the x-axis of Point γ... 

The reflection of Point γ across the x-axis is (-420, 1337)

Just by looking at the info here I can assume that black and white prints faster but let's have some solid proof for that.

So the table you are given represents the number of minutes (x) it takes to print out color pages (y):

COLOR

The equation y = 33x represents how many minutes (x) it takes to print an amount of pages (y), it's best to make an (x,y) table out of this so you can compare it to the other table in order to see which produces pages at a faster rate (Use the same x values as to get an accurate difference of rate):

BLACK AND WHITE

As you can probably tell printing pages in balck and white is faster than printing color. Using the data here I think you're good on forumlating a reason.

Just input into a calculator dude...

I don't think you can necessarily put in equations into a handheld calculator, some specialized calculators on the web may help but other than that I can't say much.

My good sir Mr. Guest I believe I can help you with this situation.

You are given:

\(\sqrt{200}+\sqrt{18}\)

You have to find muliples of 200 and 18, separate them and try to find perfect squares like so:

\(\sqrt{4* 2 * 25} + \sqrt{9 * 2}\)

4, 25, and 9 can go on the outside of the square root giving you:

\(2*5\sqrt{2} + 3\sqrt{2}\)

I'm sure you can simplify.

For a table you can just plot the points and graph them out, if the line is straight that means it's linear. If it curves in any shape or form (not straight) then it's non-linear.

For equations it's all about the LEADING TERM (Or the term with the highest power) if the leading term is just an x or y without any powers attached to them then you've got yourself a linear equation. However if the leading term has a power associated with itself then it's going to be non-linear.

Here are some examples:

(x - 2) = y     LINEAR

x^2 + 6 = 4y    NON-LINEAR

(x + 6)^3 = y    NON- LINEAR

9001x (ITS OVER 9000) + 420y = 1   LINEAR

Hope this helped. 

33 1/3% ≈ 33.3333333333333% ≈ 1/3

Now to reitterate your question, it's asking what is 1/3 of 15. I'm sure you can handle this.

For this kind of problem, I recomend you write the function out. I'll demonsrate for you:

Since she earns $35 that's a constant (meaning no variable goes with it) and $8 for every item that she sells (let the # items equal x since $8 is the coeffecient of the # of items she sells). y of course will be her total earnings. Using this information you should obtain the equation:

$35 + $8x = y

Now use the "coordinates" to plug in solutions for x and y.

Hope I helped you understand the concept. c:
