For this case what we have to take into account is the following variable:
x = represent the unknown number
We now write the following inequality:
"four times the sum of number and 15 is at least 20"
4 (x + 15)> = 20
We clear the value of x:
(x + 15)> = 20/4
(x + 15)> = 5
x> = 5 - 15
x> = - 10
The solution set is:
[-10, inf)
Answer:
all possible values for X are:
[-10, inf)
There you go ^-^ Your intersection point is at (-3, 4). Good luck :3
7.5 kilometers because half of 30 mins is 15 mins so that mean in 15 mins he can run 2.5 kilometers. So once you add 2.5 to 5 that makes 7.5
