30 students only 8 students own only a cat.
Answer:
y - 6 = -7(x + 8)
Step-by-step explanation:
Slope: m = (y2-y1)/(x2-x1) = (6 - -1)/(-8 - -7) = (6 + 1)/(-8 + 7) = 7/-1 = -7
Point-slope form: y - 6 = -7(x - -8)
=> y - 6 = -7(x + 8)
Let x be the first number
Let y be the second number
x+y=61
x-y=37 --> x=37+y
(37+y)+y=61
37+2y=61
2y=61-37
2y=24
y=12
x+y=61
x+12=61
x=61-12
x=49
Therefore the numbers are 49 and 12
Hope I helped :)
The above situation is represented by the equation v = w.r, angular velocity (w) is a constant. Therefore, velocity is inversely proportional to the radius. ( I.e if r increases v decreases and vice versa)
