Answer:
They want you to put it into an expression so that it could be expressed. So, 8 more than n would be 8+n.
Hope This Helps!!! :D
The function that has a range limited to only negative numbers is Square Root.
<h3>Can one has the range of a function to be negative?</h3>
The function of this kind is known to be a kind of radical function that is said to have even index e.g. a square root. and thus, this radicand is one that can have a negative value for some or for the values of x.
Note therefore, that The function that has a range limited to only negative numbers is Square Root and thus it is correct.

Answer:
20
Step-by-step explanation:
3x+50 = 6x-10( opposite angles are equal)
3x = 60
x = 20
Using a calculator, inserting the values of x and y, the correlation coefficient for the given data-set is of -0.9422.
<h3>How to find the correlation coefficient of a data-set?</h3>
Using a calculator, the correlation coefficient is found inserting the ordered pairs (x,y) in the calculator.
In this problem, we have that:
- The values of x are: 0.5, 1, 1.5, 2, 2.5, 3, 3.5, 4, 4.5, 5.
- The values of y are: 112.5, 110.875, 106.8, 100.275, 91.3, 79.875, 70.083, 59.83, 30.65, 0.
Hence, using a calculator, the correlation coefficient is of -0.9422.
