A triangle has sides with lengths of 8 millimeters, 15 millimeters, and 17 millimeters. Is it a right triangle?

i believe the answer is b

step-by-step explanation:

$20 bought 16 songs

so:

2 songs would cost 2 * $1.25

3 songs would cost 3 * $1.25

songs would cost x * $1.25

since renata started with $20, then her balance (y) after buying x songs would be:

y = 20 - 1.25*x

well we can use $ left as the y axis and the amount songs purchased as the x axis.   first we are going to divide 20 by 16 to get 1.25 which means that each song is $1.25. *which means after 16 songs on the x axis the lone should be at the bottom at point (0, 0).*   your equation is y=20-1.25x if you need more information just let me know : )
