Answer:
OMG THANK YOU SO MUCH I NEEDED THIS SO MUCH FOR MY MATH TEST!!!!
Step-by-step explanation:
Assuming you're concerned with interest rate problems, r is generally involved in something like the formula ...
... i = prt
So, r will have the units of ...
... r = i/(pt) = (dollars)/(dollars·year) = 1/year
That is, r is <em>(some fraction) per year</em>.
_____
Often, the fraction is expressed as a percentage. The fraction will be unitless (as percentages are), leaving the units of r as year⁻¹.
Answer:
if you flipped one of the figures you will see that they are both the same shape and the same distance from the x and y axes.

it between B and c not really sure though
Answer:
Domain = 1 to 7
Range = 4 to 28
Step-by-step explanation:
Given that:
Number of wheels used is a function of number of cars manufactured.
Number of wheels present = 28
1 car uses 4 wheels
2 cars use 8 wheels.
3 car uses 12 wheels
and so on.
Let the function be of the form:
Domain of the function is the value of 
that can be given as valid input to the function.
Range of the function is the value of 
that can be output of the function.
Let be the number of cars manufactured.
Then value of is nothing but times 4.
We are given that maximum value of can be 28.
Therefore, maximum value of input can be 7.
Minimum number of wheels can be 4 to make a minimum of 1 car.
Therefore domain is 4 to 28 and range is 1 to 7.
