Answer:
(-12, 5), (12, -5)
Step-by-step explanation:
Reflection across the origin is the transformation ...
(x, y) ⇒ (-x, -y)
Look for coordinates that are the opposites of their counterparts. You will find the appropriate answer choice is ...
(-12, 5), (12, -5)
The radius becomes the side length of six isosceles triangles. Assuming each triangle is equilateral, the height of each triangle is 4*(sqrt3).
The total area is 6 times .5*4(4sqrt3)=41.56121938 or 42 square feet
Answer:
$45
Step-by-step explanation:
In order to create a multiplication equation, we would need to use a single variable that represents the amount that each friend will pay. This can be represented by the variable x. We multiply this variable by the number of friends which should equal the total of the TV with the tax included. Like so...
$210 + $15 = 5x
Now that we have the equation we can go ahead and solve it by adding the total and the tax, and then dividing both sides by 5 in order to isolate x.
$210 + $15 = 5x
$225 = 5x
$45 = x
Finally, we can see that each friend will pay the same amount which is $45
