Answer:
(C) Annie did not make a mistake
Step-by-step explanation:
To isolate the variable k in the equation 
, we'd have to subtract 7.5 from both sides so we just had k on one side.
This is exactly what Annie did, and therefore, her answer is correct.

A computer drawing program generally has more steps compared to using a compass and straightedge, although not by much. In a computer drawing program, you can erase an error within a click of a button, compared to having to manually perfect and erase your work when using a compass and straightedge. Also, you immediately have access to an online drawing program as long as you have Internet connection and a computer compared to having to go out and buy a new compass and straightedge. Other than that, they're generally the same despite being different mediums.
Hope this helps!

Answer:
z = 30; obtuse isosceles triangle
Step-by-step explanation:
4z + z + 30 = 180
5z + 30 = 180
5z (+ 30 - 30) = 180 - 30
5z = 150
5z/5 = 150/5
z = 30
Since z = 30, and 30 = 30, two angles are congruent to each other and there is only one obtuse angle. Therefore, this is an obtuse isosceles triangle.
Answer:
It does not represent a function because a vertical line will cross the graph at more than one point.
Step-by-step explanation:
The answer is self-explanatory.
A function maps a value of x to <em>only one</em> value of y. This graph shows two (2) values of y for most values of x in the domain of the relation.
