At a store, a hat has a regular price of x dollars. During sale, the price of the hat

MariettaO [177]

Answer:

x - 0.2x

Since the price of the hat is labelled = x,

The percentage discount on the hat price = 20%,

Thus, the discount = 20% of the price marked

= Twenty percent of x

=0.2 x =0.2 x

Therefore, the hat's new price = Marked price - Discount

= x- 0.2 = x

The binomial (y − 2) is a factor of y2 − 10y + 16. What is the other factor? (y − 5) (y + 5) (y − 8) (y + 8)

Nikitich [7]

Y2 - 10y + 16
( y - 2)( y - 8 )

y • y = y2
-2 + ( -8 ) = -10
-2 • -8 = 6

= y2 - 10y + 16

to clarify your other factor is ( y - 8 )
