Step-by-step explanation:
It is because for every x value there is a y and the x value does not repeat to any y values.
Answer:
ok and what else there is 80 percent left
Step-by-step explanation:
Answer:6x*4
Step-by-step explanation:
(12-6)x(16-12)
6x*4
a = 4, b = -21, c = -18
to keep from getting "mixed up", evaluate the discriminant first ...
b<sup>2</sup> - 4ac = (-21)<sup>2</sup> - 4(4)(-18) = 729
sqrt(729) = 27
x = (21 +/- 27)/8
x = -3/4, x = 6
since the discriminant is a perfect square, the original quadratic will factor ...
4x<sup>2</sup> - 21x - 18 = 0
(4x + 3)(x - 6) = 0
x = -3/4, x = 6
