Answer:

x = 350

Step-by-step explanation:

x - starting amount

\frac{2}{7} x  = after transport

\frac{1}{5} (\frac{2}{7} x) = after sweets

\frac{1}{5} (\frac{2}{7} x) = 20

(\frac{2}{35} x) = 20

2x = 700

x = 350

sashaice [31]

Answer:

Set of all real numbers

Step-by-step explanation:

When we talk of domain, we mean the possible values of x that the equation can take without being undefined

So x-values that makes the equation defined are the domain of the graph

From the diagram, we can see that the graph extends from negative infinity to positive infinity

What this mean is that the possible values here come from the top right and extends to the left

So this means that the range of possible values are the set of all real numbers
