The unit rate is another way of saying speed, so we divide the distance over the time. We can pick on any row
If we pick row 1, then, speed = distance/time = 90/2 = 45
Row 2 says the same thing: 135/3 = 45
So does row 3: 225/5 = 45
and so on
Because the speed is 45 mph, the unit rate is 45 miles in one hour. The term "unit" implies how much distance can be covered in one unit of time, in this case 1 hour.
You have the correct answer. Nice work.
In this relation we have two ordered pairs:
( 5, 7 ) and ( 5, 8 )
For x = 5 : f ( x ) = 7 and also for x = 5, f ( x ) = 8. This is not possible for a function.
Answer:
b ) No. The relation is not a function.
Hello,
Degre 5==> even number of imaginary roots and odd number of reals.
Real roots must be a divisor of 7.

Answer: The answer would be a line that is not as steep and a reflection in the line y = x.
If the a value in the equation is greater than 1, we will have a line that is steeper than the line y = x.
Now, we we take the inverse of the line, it will have a slope that is lower than y = x.
The graphs will be reflected in the line y = x.
Try graphing y = 3x and 3y = x.
