Which function has the same graph as x + y= 11?
2 answers:
Answer:
<h2>B. f(x) = -x + 11 </h2>Step-by-step explanation:
The choices for this question are
A. f(x) = -y + 11
B. f(x) = -x + 11
C. f(x) = x − 11
D. f(x) = y − 11
First of all, we need to know that<em> f(x) </em>expresses the same variable than <em>y, </em>basically <em>y=f(x).</em>
Being said that, B and C are the viable choices, because the other ones don't make sense because they don't include the independent variable <em>x.</em>
One way to find the right answer is by taking the given expression and solving for <em>y:</em>
Therefore, the right choice is B. They have the same graph, because they have the same linear function.

Make a set of the DVD's sold:
In month 1, Aaron sold 20 DVDs. There is no data for month 0.
There is a constant increase of 30 DVDs every month. We can make an equation out of this to fit this data set:
a represents the DVDs made.
We need to subtract 10 in this equation, as the starting point is 20, and the increase of 30 is different from the increase from n = 0 to n = 1.
We are looking for the amount of DVDs Aaron sold on the 13th month. Plug 13 into the equation:
The predicted number of DVDs Aaron will sell on the 13th month is 380.
