Answer:
y = 1x + 5
Step-by-step explanation:
Because you pay $5 for the cup once, and to refill it, you have to pay $1 as how many times as you want.
So, put 2 hours into minutes. You get 120. Now, seeing how you have 20 song requests, and each one takes 3.5 minutes, multiply those two values. Now you have 70. After doing that, just subtract 70 from 120 and get 50.
tada
answer is 50
Standard form of a circle" (x-h)²+(y-k)²=r², (h,k) being the center, r being the radius.
in this case, h=-2, k=6, (x+2)²+(y-6)²=r²
use the point (-2,10) to find r: (-2+2)²+(10-6)²=r², r=4
so the equation of the circle is: (x+2)²+(y-6)²=4²
8x - 2y = -8
-5x + 2y = -1
3x = -9
x = -3
