Answer:

The number of red fish are 9

Step-by-step explanation:

X = number red fish

Y = number orange fish

then,

X + Y = 30

Y = 12 + X

then replacing Y

X + (12 + X) = 30

2X = 18

X = 9

Answer:

x-intercept(s): (-2, 0), (6, 0)

y-intercept(s): (0, -6)

Step-by-step explanation:

An x-intercept represents the point(s) at which the parabola intersects the x axis. A parabola can have 0, 1, or 2 x-intercepts.

A y-intercept represents the point at which the parabola intersects the y axis. A parabola always has exactly 1 y-intercept.

Hope it helps :) and let me know if you're still confused.
