Bicycle has 2 wheels and 2 pedals
tricycle has 3 wheels and 2 pedals
EQ 1 : 2b + 2t = 170 pedals
EQ 2: 2b +3t = 206 wheels
subtract EQ 1 from EQ 2
2b +3t = 206 - 2b + 2t = 170 = t=36
there were 36 tricycles
36 x 2 = 72 pedals
170 pedals - 72 = 98 pedals left
98/2 = 49 bicycles
36 Tricycles and 49 bicycles
Y=2/x. this equation has degree -1 whereas linear functions have degree 1
y=6x²-7 is nonlinear as it is degree 2
1. Felicia is 2 years old (2 cubed is 8)
2. If you take 288 times 3 and divide it by 4= 216
And 216 is a perfect cube
