Your gym membership costs $33 per monthafter an initial membership fee. you paid a total of $228 after 6 months
Maru [420]
1. let x be the number of months paid. 2. let 33x be the dollar value of the cost paid after x months (no initial fee yet) 3. let 33*5=165 be the cost paid on monthly basis for 5 months . But the total cost is $225 dollers after 5 months. the implies that the membership fee is 225 -165=dollers. 4. let TC be the total cost. 5. then the total cost TC=33x+60. 6. after 10 months , total cost TC= 33*10+60=330+60=390dollers.

Which description compares the vertical asymptote(s) of Function A and Function B correctly?
r-ruslan [8.4K]
Function A:  f(x)=\frac{1}{x}+4.  Vertical asymptotes are in the form x=, and they are a vertical line that the function approaches but never hits.  They can be easily found by looking for values of <em>x</em> that can not be graphed.  In this case, <em>x</em> cannot equal 0, as we cannot divide by 0.  Therefore <em>x</em>=0 is a vertical asymptote for this function.  The horizontal asymptote is in the form <em>y</em>=, and is a horizontal line that the function approaches but never hits.  It can be found by finding the limit of the function.  In this case, as <em>x</em> increases, 1/<em>x</em> gets closer and closer to 0.  As that part of the function gets closer to 0, the overall function gets closer to 0+4 or 4.  Thus y=4 would be the horizontal asymptote for function A.
Function B:  From the graph we can see that the function approaches the line x=2 but never hits.  This is the vertical asymptote.  We can also see from the graph that the function approaches the line x=1 but never hits.  This is the horizontal asymptote.

Which is an equation of the line that passes through the points (-1,9) and (4, 24)?
choli [55]

Answer:

y = 3x + 12

Step-by-step explanation:

Slope (m) = 24-9/4-(-1)

= 25/5

= 3

Using point (-1 , 9)

y - y1 = m (x - x1)

y - 9 = 3 (x - -1)

y - 9 = 3 (x + 1)

y - 9 = 3x + 3

y = 3x + 3 + 9

y = 3x + 12

luke says you can always add and you can always multiply to join groups. is he correct? why or why not
Nataly_w [17]
He is incorrect because you can multiply unlike terms like y and x and you'll get xy but you can't add unlike terms like 13x+16y is the simplest it can be.
