Answer:

D(5,-8)

Step-by-step explanation:

The given point is (-3,-2)

When we reflect in the line y=k, we use the rule (x, 2k-y)

This implies that:

(-3, - 2)\to (-3, 2*-5--2)

(-3, - 2)\to (-3,  - 8)

When we reflect in the line x=k, we use the rule

(x,y)\to (2k-x,y)

Now we have x=1

This implies that:

( - 3, - 8)\to (2 \times 1- - 3, - 8)

( - 3, - 8)\to (5, - 8)

satela [25.4K]

A toy cost 0.85p in January.

Step-by-step explanation:

Mark down in January = 15%

Let,

Mark down in January = 15% of price in December

Mark down in January = \frac{15}{100}*p

Mark down in January = 0.15p

Price of toy in January = Price in December - Mark down

Price of toy in January = p - 0.15p = 0.85p

A toy cost 0.85p in January.
