The correct answer is b) the function has an inverse because if passes the horizontal line test.
Answer:
Option C 
Step-by-step explanation:
we have

The compound inequality can be divided into two inequality
-----> inequality A
----> inequality B
Solve inequality A


Divide by -3 both sides
when you multiply or divide both sides of an inequality by a negative number, you must reverse the inequality symbol

Rewrite

The solution of the inequality A is the interval (-∞,-3]
Solve the inequality B


Divide by -3 both sides
when you multiply or divide both sides of an inequality by a negative number, you must reverse the inequality symbol

The solution of the inequality B is the interval [-6,∞)
The solution of the compound inequality is
[-6,∞) ∩ (-∞,-3]=(-6,-3]

Answer:
x=121
Step-by-step explanation:
√x+1-4=8
1) Combine alike terms:
√x-3=8
2) Add 3 to both sides:
√x=11
3) Cancel the <u>square root</u> by squaring both sides:
x=121
The container is a cube with side length of 8 cm. If the crystals are also cubes with side length of 1 cm, then 8 crystals will fit along one side of the container. Since all the sides are the same length on a cube, we can take the 8 crystals and cube it to find the total amount of crystals in the container.

= 8·8·8 = 512
Each crystal costs 5 cents, so multiply 512 crystals by $0.05.
0.05(512) = $25.60
