Answer:
is the inequality to find the Domain of f(x)
Step-by-step explanation:
When we have a function where the variable "x" is inside a square root, we find its Domain by looking for all those values x for which the function is defined for the root, which means all the x-values that make the expression inside the root larger than or equal to zero, avoiding the values smaller for which the square root is not defined.
Therefore, in this case , for

we ask for the x-values that verify:

where we have isolated x on one side of the equal sign.
This would be the definition of the Domain of the function.
Answer:
The relation has an undefined slope if the graph line is just vertical.
4 sweets = 28p
1 sweet = 7p
7 sweets = 7 x 7 = 49p
Answer:
6
Step-by-step explanation:
Given information:
Interior angle of a polygon cannot be more that 180°.
One interior angle = 
Other interior angles are = 
Let n be the number of sides of the polygon.
Sum of interior angles is


Combine like terms.
.... (1)
If a polygon have n sides then the sum of interior angles is

.... (2)
Equating (1) and (2) we get
Isolate variable terms.
Divide both sides by 52.
Therefore the number of sides of the polygon is 6.
