So, two other algebraic expressions based on this situation are:


Assuming the left is minutes and the right is distance, Mario runs 1 mile in 7 minutes
(a) y=x/7
(b) the rate of change is 7
(c) if he ran for 70 minutes then his distance is 10 miles.
*for (c) just plug in the number given. Replace it with x and divide it by 7.*
Answer:
The square root of this is 80047
Step-by-step explanation:
This is an example of empirical probability, although it gives the same ratio as a theoretical probability, because we based the result on our experiment
Answer:
y = -2x + 7 and y = x - 2
Step-by-step explanation:
2x + y = 7
y = -2x +7
x - y = 2
-y = -x +2
y = x - 2
