Answer:
Option (3)
Step-by-step explanation:
There are two inequalities graphed in the figure attached.
1). Solid line having shaded above the solid line (passing through origin) will be represented by the equation,

2). Another dotted line having shaded area below the line will be represented by the inequality,

Common shaded area of these inequalities will be the solution area.
All the ordered pairs lying in this area will be the answer.
In the given options,
Ordered pairs given in Option (3) lie in the common shaded area.
Answer:
Given the function:

The rule of reflection across the x-axis is given by:

Apply the reflection over the x-axis on the given function we have;

Multiply both sides by -1 we get;

or

Therefore, function represents a reflection f(x)=3/7(2)^x over the x-axis is, 
The value of 28 tens is 280 because a ten is literally 10 you only multiply 28*10= 280 So the value of 28 tens is 280.
