y = -1
6x - 4 = -10
6x = -6 then x = -1
Answer:
B
Step-by-step explanation:
The zeros of the quadratic occur at x = 0 and x = 6
Thus the factors are x and x - 6
Let's say the tv was 100$ . Reduced by 20% means the tv is now 100 - 20 = 80% of the original price.
0.8(100) = 80$
Reduced again; by 10% means that it is now 100-10 = 90% of the 80$
0.9(80) = 72$
sale price ÷ original price
72$ / 100$ = 0.72 which is 72% of the original price. Which is a mark down of:
100 - 72 = 28%
The new price is 28% lower than the original price.
