Answer:

b. A year and a half

Step-by-step explanation:

First, we can find the total cost

1512+263=1775

Next, we can divide by 50 in order to find out how many months it will take for the panel to pay for itself.

\frac{1775}{50} =35.5 months

This is very close to 36 months, which is <u>A year and a half</u>.

Which expressions are equivalent to 16? Select each correct expression
photoshop1234 [79]

Answer: Choose 2 to the 4th power, 4 to the 2nd power, and 16 to the power of 1

Step-by-step explanation:

When working with exponents, whatever number is the corner of another number, multiply it by itself. For instance, if you have 2 to the 4th power, multiply 2x2x2x2 which is 16. Also there is 4 to the 2nd power which is 4x4 which is also 16. Lastly you have 16 to the power of 1 and anything multiplied by 1 stays the same.

Answer:

A) (3,-8); Reflection

Step-by-step explanation:

The question kind of gave you a hint. Look at how the coordinate point is arranged...

(-y,-x)

That means all positive become negatives and all negatives become positives. This gives you the coordinate of (3,-8).  

As for reflection or rotation, the image's coordinates FLIPPED, like how images do in a mirror's reflection.

This means the answer would be A) (3,-8); Reflection.
