ANSWER
D. As the x-values increase, the y-values would decrease
EXPLANATION
The given function is
The slope of this function is
Since the slope is negative, there is a negative or an inverse relationship between x and y.
As the values of x increases, the values of y decreases.
Also, as the values of x decreases, the values of y increases.
The first option is not true because as x is becoming bigger and bigger negatively, y will become positive.
For instance, when
This implies that,
Options B is obviously not true because the function has a negative relationship between x and y.
Option C is also false because, x can be positive since it is the independent variable.
See graph
Therefore, the correct answer is option D.

Answer:
The depth of the reflector is 700 feet.
Step-by-step explanation:
The cross section of a parabolic reflector is just a parabola (see the figure below). Because it has a vertical axis of symmetry and its vertex is at (0,0) the equation of the parabola is:
With p the distance to the focus (p=6ft), the equation for our particular case is:
Note that because the reflector extends 5.5 feet to either side of the vertex, the extreme sides of the parabola are on the curve so they satisfy our parabola equation (3). Let’s concentrate on the right extreme of our parabola with x-position 5.5 ft using this number on (3) equation we can find the respective y-position
and that correspond to the depth of the parabolic reflector.
Answer:
Part A: x= number of shifts he works at the theater y= number of dog-walking jobs.
Part B: The only terms are 85x and 15y.
Part C: 15y
Step-by-step explanation:
Part A: The variables are the xy reasoning to this is due to them being the replacements of the numbers which aren't known.
Part B: The terms are pieces of the expression which are together.
Part C: It is the one used above for the dogs " $15 for every dog-walking job."
