-3 < x + 2 ≤ 7
Graph. Isolate the x. Subtract 2 from both sides (for both equations):
-3 < x + 2
-3 (-2) < x + 2 (-2)
-5 < x
x + 2 ≤ 7
x + 2 (-2) ≤ 7 (-2)
x ≤ 5
Note that it looks like:
-5 < x ≤ 5
Graph. You're graph will look like the attached picture

Answer:
The cyclist's average speed is 13.43 
Explanation:
Speed is a quantity that expresses the relationship between the space traveled by an object and the time used for it. That is, speed is the magnitude that expresses the variation in position of an object and as a function of time, which would be the same as saying that it is the distance traveled by an object in the unit of time.
Average speed relates the change in position to the time taken to effect that change:
In this case:
- total distance traveled= 32 km + 15 km= 47 km
- total time= 3 hours that the cyclist travels + 30 minutes of rest = 3 hours + 0.5 hours (being 60 minutes equal to 1 hour, then 30 minutes equals 0.5 hours) = 3.5 hours
Replacing:
and solving, you get:
speed= 13.43

Answer:
Benjamin
Explanation:
In the first mission to go and look for food during the time of famine, the ten sons of Jacob went and found their brother serving in Egypt. They were given conditions that in case they were to go back, they should come back with their brother Benjamin. However, when Jacob was told by Judah that they should go with Benjamin back to Egypt, he was reluctant at first to let him also go. This account is found in Genesis chapter 43
Explanation:
When a bullet is fired from a rifle, the actual firing makes a distinctive sound, but people at a distance may hear a second because the bullet creates a shock wave , a little sonic boom( speed of this sonic boom is greater than the speed of sound). It is this sound only that is heard by the people at a distance from the gun.
