Answer:
B
Step-by-step explanation:
Sarah's house is not shown in graph
They are similar because they share the same point, therefore they also have the same angle measure at that point. They are congruent because if the AA Similarity Theorem
Answer:
y=1/3x
Step-by-step explanation:
I'm assuming that the "linear parent function" is
. If so:
A. is true.
In fact, the slope of a line written in the form
is
, and the line
is given by 
C. is true.
Since the origin is the point
, if we compute the function at
, we want
. This is quite trivial since 
D. is true.
The domain is affected by denominators (they can be zero), even roots (they don't accept negative inputs) and logarithms (they don't accept non-positive inputs). Since this function has none of these three, the domain is all real numbers.
B. is FALSE.
The range of a function is the set of numbers obtained as output, for all possible inputs. Since, in this case, the input and the output are the same thing, if you give a negative input, you will receive the same negative output. So, the range doesn't consist only of positive numbers.
Answer: -11
Step-by-step explanation:
For this problem, it is important to look at the domains next to the function. In this problem there is a function for when x < 1 and when x ≥ 1. 3 is greater than 1, so we will use the second equation.
From there, plug in 3 for x and solve.
-2x - 5
-2(3) - 5
-6 - 5
-11
