Answer:
y = -0.25*x + 2
Step-by-step explanation:
y = a*x + b
is perpendicular to the line 4x+y=3 -> a = -1/4 = -0.25
y = -0.25*x + b
b = y + 0.25*x = -3 + 0.25*4 = -2
-2
15x+6=6x-12
15x-6x=-12-6
9x=-18
x=-2
0.3
3
The factor (x - 8) has 1 zero at x = 8
The factor (x + 3)² has a zero at x = - 3 of multiplicity 2
In total there are 3 zeros
