Hello,
A cubic polynomial with -2,1,2 as roots is
f(x)=k*(x+2)(x+1)*(x-2)=k(x²-4)(x+1)=k(x^3+x²-4x-4)
Looking the answers ==>k=1
==>Answer A
The first inequality is
(2/3)x - 3 ≥ y
or
y ≤ (2/3)x - 3 (1)
The second inequality is
y + (2/3)x < 4
or
y < 4 - (2/3)x (2)
A graph of the two inequalities indicates the solution as a shaded region in the figure below.
Answer:
112/17.92 = x, y = 112 + x
Step-by-step explanation:
You have to get x first, then plug in to next equation.
Answer:
The answer is

Step-by-step explanation:
By using Pythagoras low
Then we can find that

Answer:
(3x + 4)° + 50° = 90° (complement angle)
3x° + 4°+ 50° = 90°
3x° +54° = 90°
3x° = 90°- 54°
x° = 36°/3
x° = 12°
