It is shown that he goes down in a slower time than he does going up.
You'll calculate the amount it was decreased by :
15% is also 15/100
15/100 * 42000
The two 0's in 100 cut 2 of the 0's in 42000 making it :
15/1 * 420
15* 420 = 6300
So, 6300 is the amount that the price is decreased by, but the question says the price of the PC (personal computer) after the decrease has happened not the price it decreased by :
So,
42000 - 6300 = 35700.
Well, I don’t necessarily remember how to sketch a plane. However, I can help get you started by defining some words they use and hopefully you will be able to do this on your own!
So this plane is made up of three points, names E, D and B. (Edit: This plane may be made up of four points, because of point A.)
E and B are collinear with A. This basically means that they all are on the same line.
D is a vertex. This basically means that it is a dot that these two lines called rays will shoot out of it. I will attach a picture of a vertex.
CD and FD are called rays. See those little lines above them? I’ll be sure to attached another image so that you know what I’m taking about. Anyway, that means they are rays. Rays are like never ending lines; they start at a point and the line will go on for infinity.
(Edit: where did the point f come from? I really wish you would have attached the full picture...)
Whelp, that’s all I’ve got! Good luck!!
(Edit: looks like I can only attach one picture...I’ll comment the other.)
Answer:
Letter c
Step-by-step explanation:
You are distributing the 7 to each term in the parentheses.
7(8x) is 56 x
Here is the tricky part. You can think of it a couple of ways:
7(-4y) = -28y a positive times a negative is a negative.
or 7(4y) = 28 , but then remember that you are subtracting so it will become -28
7(6) = 56
56x - 28y +42
