1 x3 + 8x3 = 9 x3
.6x = 22
x = 36 2/3
.55 ( 36 2/3) =121/6
Hmmmmmm..... is this perhaps 64 feet or something else ?
Since tigers and giraffes have the same number of feet and heads g = t
62 feet = 2k + 4 ( 2g )
22 heads = k + g + g = 22 = k + 2g <===== multiply by -2 and add to top equation to get
18 = 4 g
Integers x-1 x x+1
(x+1)(x-1) =3x + 17
x^2 -1 -17-3x = 0
x^2 -3x - 18 = 0
(x-6)(x+3) x = 6 or -3 5 6 7 ( or -4 -3 -2 <==== negative integers solution)
y coordinate is - 1/2
a+b = 485
a-b = 303 add the two equations
2a = 788
a = 394 tons now you can calc b
f(a) = a^2-2a = 8
0 = a^2 -2a-8
0 = (a-4)(a+2) a = +4 or -2
7x^2 + x - 5 = 0 ab = -5/7
