Answer:
If 78 is their grand total, then those 3 consecutive even numbers have to be 24, 26 & 28
Answer:
Hey I don't I can graph it but I can give you the points.
Step-by-step explanation:
Table
-0.5 1
-2.5 4.1
0.42 -.84
Just try your best to estimate where it is supposed to be on a graph.
the answer i got was 5% , because all you have to do is perform a proportion . you put $400 which is what avery made over the total money of the sale which is $8,000 . then you put n the variable over 100 so you can find the percentage of her commission . now you have to cross multiply , so you would multiply $400 and 100 . & $8,000 with the variable n . in the end you'll get 400*100= 40,000 and 8,000n= 8,000n . now you would divide 40,000 by 8,000 to get rid of the 8,000 off the variable . so 40,000/8,000= 5 . so the percentage of her sale is actually hers is only 5% .
Let's take a look at the <em>relationship</em> between x and y in this function. When we look at the first non-zero pair, (-1, 1), we can see that, in the transition from x to y, our x value was had to have been multiplied by -1. For now, we could tentatively say that y = -x. Unfortunately, the next pair, (-4, 2), debunks this hypothesis pretty quickly, as 2 ≠ -(-4). We'll need to reexamine the relationship between x and y here.
One patter that we can be fairly confident in is that multiplication by -1; the sign is flipped from negative to positive when we go from x to y in each case, so we can hold onto that component of the function. Something else is happening before that sign flip, though, and we'll need to look into that by seeing how else the numbers are connected.
Ignoring the negative signs for a moment, let's take a look at the pairs (1,1) and (4, 2). We can transform 1 to 1 pretty easily; we simply multiply or divide it by 1. From 4 to 2, we can either divide it by 2 or multiply it by 1/2. Let's thing in terms of division for now. We know that
1/1 = 1 (obviously)
4/2 = 2
We might have something here! It looks like the number we divide by and the number we obtain are the same, so let's explore this further. Multiplying both sides by those denominators, we find:
1 = 1²
4 = 2²
Almost there! To finally find the relationship, we just square root both sides to get:
√1 = 1
√4 = 2
So that was the function we'd been looking for - a square root! Putting that together with what we said about changing the sign at the beginning, we have:
y =√(-x)
To verify this, we just need to plug in a few pairs, and we find that indeed:
1 = √-(-1) = √1 = 1
2 = √-(-4) = √4 = 2
