Answer:
Additive inverse
Step-by-step explanation:
Every real number has an additive inverse, i.e., for every real number x, there exists a real number y such that
![x+y=0](https://tex.z-dn.net/?f=x%2By%3D0)
Obviously, y is simply -x.
So, in this case, we can see that 3 and -3 are additive inverse, because they give 0 when summed.
Answer:
4,050 cubic feet
Step-by-step explanation:
The figure is made up of a square pyramid and cube
Therefore:
Volume of the figure = volume of the square pyramid + volume of the cube
✔️Volume of the square pyramid = ⅓*a²h
a = 15 ft
h = 9 ft
Volume of square pyramid = ⅓*15²*9 = 675 ft³
✔️Volume of the cube = s³
s = 15 ft
Volume of the cube = 15³ = 3,375 ft³
✔️Volume of the figure = 675 + 3,375 = 4,050 cubic feet
|2x + 1| < = 5
-5 < = 2x + 1 < = 5 ...subtract 1
-5 - 1 < = 2x + 1 - 1 < = 5 - 1
-6 < = 2x < = 4 ....divide by 2
-6/2 < = (2/2)x < = 4/2
-3 < = x < = 2
