Answer:
8
Step-by-step explanation:
Create an expression to model the situation. One can do this by simply rewriting the written expression in terms of numbers and variables. Use the variable (x) to represent the unknown value.
Simplify this expression,
Use inverse operations to solve for (x),
If f = {(4, 2), (6, 1), (8, 4), (10, 2), (12, 5)}, what is the range
UNO [17]
Answer:
Range = {2,1,4,5}
Step-by-step explanation:
When a function is given in the form if a relation. i.e. ordered pairs.
When the function is given in the form of ordered pairs then the set of first elements i.e. x-coordinates of all ordered pairs forms domain while the set of second elements i.e. y-coordinate of all ordered pair is called range.
So in the given function:
Range = {2,1,4,5}
The repeating values are only written once..
Answer:
Step-by-step explanation:
The equation of a circle is 
where 
is the center of the circle and 
is the radius of the circle.
Given that 
and it passes 
, their distance between each other must the radius of the circle, so we can use the distance formula to find the radius:
Therefore, if the length of the radius is 
units, then 
, making the final equation of the circle
