Answer:
x=25
the area of x squared is then 625
Step-by-step explanation:
3x +5 = 80
3x= 75
x=25
the area of x squared is then 625
Either mean or median, they are both 14 in this data set.
Answer:
Option b is correct
.
Step-by-step explanation:
Domain is the set of all possible values of x where function is defined.
Given the function:

To find the domain of the given function:
Exclude the values of x, for which function is not defined
Set denominator = 0

By zero product property;
and 
⇒x = 0 and 
⇒x = 0 and 
Therefore, the domain of the given function is:

Answer:
Option (1).
Step-by-step explanation:
In the figure attached,
Houses of three friends Jo, Boris and Carrie are located at the vertices of a triangle.
They want to meet at a place which equidistant from these vertices.
A point in a triangle which is equidistant from the vertices is its Circumcenter.
A circumcenter of a triangle is a point of intersection of perpendicular bisectors of its sides.
Therefore, the next step to find the meeting place should be,
Option (1). They should find the midpoint of the segments which connect their houses.
Answer:
- A: 9.03
- B: 2 years
- C: 2012, negative
Step-by-step explanation:
A. For x = 18, y ≈ 9.03 . . . . homicides per 100,000
__
B. The curve has a maximum at about x ≈ 2.003, about 2 years after 1990.
__
C. The model produces negative numbers for x > 22. It will not be valid after 2012.
