Answer:
x^3-10x^2+x+120
Step-by-step explanation:
Assuming you mean roots -3, 5, 8
These happen when we have (x+3)(x-5)(x-8)=0
Expand this
(x^2-2x-15)(x-8)=0
=x^3-2x^2-15x-8x^2+16x+120
=x^3-10x^2+x+120
15% of R560 - 15% of R500
=> 0.15 × 560 – 0.15 × 500
=> 0.15 ( 560–500)
=> 0.15 × 60
=> Rs. 9

The answer is A because u can subtract the 3x to get 2y by itself then divide by 2 to completely get y by itself and it would be y=-3/2x - 9/2
Answer:
y = -3x
Explanation:
k = -3
y ¤ x......where ¤ represents the Greek alpha sign
y = k • x
y = -3 • x
y = -3x
