Answer:

A‘‘ (1,6)

Step-by-step explanation:

after a reflection about a horizontal line the x coordinates remain the same

the middle point of the segment AA’ lies on the line so it has y = -1

so we have

(y+y’)/2 = -1

y’ = -2 -y

y‘ = -2 -2 = -4

so A‘ (1,-4)

we can use the same reasoning to find the reflection about y = 1

x‘ = x

(y + y’)/2 = 1

y‘ = 2+4

y’ = 6

A‘‘(1,6)

Alexxandr [17]
<span>STEP 1: Stick a "y" in for the "f(x)" guy:STEP 2: Switch the x and y. ( because every (x, y) has a (y, x) partner! ):STEP 3: Solve for y:<span>STEP 4: Stick in the inverse notation, continue. 1 2 3.
these are the steps and that is not correct </span></span>

What is the cost of operating a 3.00-w electric clock for a year if the cost of electricity is $0.0900 per kw · h ?
brilliants [131]
We must take into account the following change of units:
 1kw = 1000w&#10;&#10;1 year = 365 days&#10;&#10;1 day = 24 hours
 Applying the change of units we have that the electric consumption for 1 year is given by:
 (3) * (1/1000) * (365) * (24) = 26.28 kw * h&#10;
 Then, the total cost is given by:
 (26.28) * (0.0900) = 2.3652&#10;
 Answer:
 
the cost of operating a 3.00-w electric clock for a year is:
