Step-by-step explanation:
115 = 5x + 15
115 - 15 = 5x
100 = 5x
20 = x
Okay, so the first thing we have to do is take 6ft and convert it into inches so we get the equation (6x12)+6 6 times 12 is 72 so that gives us 72in plus 6 which is 78 and with that answer we take 78in and divide it by 6.17 which is 12.18. She has a long arm measuring i while feet and 18 inches lol
No because a right triangle always has a right angle
You can easily test this if you know that (6, -10) corresponds to (X, Y). Knowing this, you can:
X = 6
Y = -10
you put this into your equation:
-10 = 3*6 - 8
calculate it:
-10 = 18 - 8
-10 = 10
This is not true of course, -10 is not equal to 10. Therefore, (6, -10) is not a solution of y = 3x-8 :)
