I don’t understand this and I did take notes on this on the computer but I still don’t understand it.

Serggg [28]

Answer:

I'[−3, −2], Q'[2, 0], ?'[0, 1], E'[−3, −1]

Step-by-step explanation:

The line of reflection is at y = −2, so looking at the line and where the coordinates of the shape are, you will have this:

I[−3, −2] → I'[−3, −2] (on the line, so it remains the same)

Q[2, −4] → Q'[2, 0]

?[0, −5] → ?'[0, 1]

E[−3, −3] → E'[−3, −1]

I am joyous to assist you anytime.

Without actually carrying out the steps of multiplication, determine whether the product of 15.1 and 0.9 will be larger or small

yan [13]

Answer: Smaller

Step-by-step explanation: The product of 15.1 and 0.9 will be smaller than 15.1. This is because 0.9 is smaller than 1 and since 15.1 * 1 is 15.1, we know that anything smaller than 1 will result in the product of it and 15.1 being smaller.
