The rate of change in an equation can usually be found with what number is being multiplied with X or whatever variable you have. So in this equation it shows that a ride's cost goes up the more miles (X) you need to go, the number being multiplied would be 2.50 so for each mile you need to go it increases by $2.50. There is a small note though, since you need to subtract 3 from whatever your X is, that means that there is a minimum of 3 miles you need to go for an uber ride to be valid. Regardless, the rate does not change, just has a different minimum.
So the rate of change would be $2.50 per mile
The square has 4 sides of the same measure.
If square SQUA has a side measuring 25 mm, it means side QU measures the same.
Also, if quadrilateral AQER is a square two, then its diagonals bisect each other, then QU is equal to UR.
Thus, QR measures:

The answer is 50 mm
2.8x10^-5 ; 2.8x10^-3 ; 2.8 ; 2.8x10^2 ; 2.8x10^4
Answer:
?=9
Step-by-step explanation:
We have a special right triangle, the 45-45-90 triangle.
In a 45-45-90 triangle, the side lengths are x, and the hypotenuse is x√2.
Since we know that the side length is 9, this means that:

The ? is 9.
