For this case, we must find the equation of the line.
 The generic equation of the line is:
 y-yo = m (x-xo)

 The slope of the line is:
 m =  \frac{y2-y1}{x2-x1}
 Substituting values we have:
 m = \frac{15-12}{2-0}
 Rewriting:
 m = \frac{3}{2}
 m = 1.5
 We now choose an ordered pair:
 (xo, yo) = (0, 12)
 Substituting values we have:
 y-12 = 1.5 (x-0)
 Rewriting the equation:
 y= 1.5x+12
 For 20 visits, we evaluate the equation when x = 20.
 We have then:
 y= 1.5(20)+12
 y= 30+12
 y= 42
 Answer:
 
The discounted entrance fee is 1.5$. The total cost is 42$ after 20 visits

Total cost for a computer if pay 600 down and 35.00 a month for 12 months
Stella [2.4K]
First step you would have to do would be to times 35 by 12 to see how much you would have to pay for 12 months.

35 x 12 = 420

Then, as you said, you a down payment of 600 so then you'd add.

600 + 420 = 1,020.

So the total cost of the computer would be $1,020.

2 times what eqvals 49
Naddik [55]
So what you can do is take 49 and divide it by 2 cause times is multiplication so if you take 49 and divide that by 2 you would get 24.5. Now if you plug so like 24.5 · 2 would would get 49.

F(x) = 0.5x + 10

0.5x + 10 = 18.5
0.5x = 18.5 - 10
0.5x = 8.5
x = 8.5/0.5
