What are the domain and range of f(x)=-37

balandron [24]

Answer: Domain: All real numbers. Range: y=-37

Step-by-step explanation: The function of f(x)=-37 is a horizontal line that goes from negative infinity to positive infinity. The domain can be any number since there is no limit on what the x value can be. The range will always be y=-37 because no matter what x will equal, y will always be equal to -37 in the function of f(x)=-37.

The local newspaper has letters to the editor from 70 people. If this number represents 5% of all of the newspaper's readers, h

Alex Ar [27]

Answer:

This shows us that there are 1400 readers.

Step-by-step explanation:

To work this out you would first need to find how many times 5% goes into 100%, You can do this by dividing 100 by 5, this gives you 20. This is because the whole amount is equivalent to 100%.

To work out the total number of readers you would multiply 70 by 20, this gives you 1400. This is because we know that 70 is equivalent to 5% and that 5% goes into 100% 20. So by multiplying 70 by 20 we are working out the total (100%), and that this shows us there are 1400 readers.

1) Divide 100 by 5.

$100/5=20$
