The ordered pairs that are located 8 units away from the point (2, 1) are; (-6,1), (10,1), (2,-7) and (2,9)
<h3>Ordered pairs and Distance.</h3>
The ordered pairs which can be 8 units away from the point, (2, 1) are pairs in which case, either x or y coordinates or both are 8 units from the given pair of coordinates (2,1).
Hence, the following pair of coordinates have x or y coordinates which are 8 units away from the x or y coordinates of the given pair of coordinates.

Answer:
x ≈ 1091.63
Step-by-step explanation:
Using the rule of logarithms
x = n ⇔ x =
note that ln x is to the base e
Given
ln(x + 5) = 7, then
x + 5 = ( subtract 5 from both sides )
x = - 5 ≈ 1091.63 ( nearest hundredth )
How you do this is using the formula speed = distance/time. So this is 100/5 which is 20 meters a second. Using the conversion factor (can google "20 meters per second is how many mile") 20 meters a second = 44.7 miles per hour.
In conclusion, the answer you're looking for is D. 44.7 miles per hour.
Fourteen hours. The equation is 5x+20=90. Solve for X.
