Answer:
7x-1
Step-by-step explanation:
14 + 7x - 15 = k
7x - 1 = k
Finding x,
14 + 7x - 15 = k
=> 14 + 7x = k + 15
=> 7x = k + 15 - 14
=> x = (k + 1)/7
So, 7 * (k+1)/7 - 1 = k
k + 1 - 1 = k
=> k = k
So the answer is true that 7x - 1
Let's see -
3,839 would be rounded UP to 4,000, since the 3 tells the 8,
"Hey, can I borrow a cup of sugar?" And the 8 says,
"Of course!"
Notice the 3 says "A cup of sugar", which is ONE.
If you add ONE to three, it makes 4. Then the rest of the numbers turn into zeros.
OR, you could go about it with a helpful rhyme:
5 or more, raise the score!
4 or less, let it rest!
This just shows you that if the number is bigger, round UP.
If the number is smaller than 4, round DOWN or keep it the same.
In this case, 8 is larger than 3, so we would round up to 4,000.

Answer:
Step-by-step explanation:
the difference is 56 because if you add and divide them by 3 and -2 you will get 56
Given:
Body length (meters) Mean Speed (meters/seconds) <span>4 0.89 </span>
4.5 0.83 4 0.76 6.5 0.94 5.5 0.94
The horizontal axis is the x-axis. The values reflected in this axis is the body length of the shark.
The vertical axis is the y-axis. The values reflected in this axis is the mean speed.
Graph your own scatter plot.
