SOMEONE PLS ANSWER THIS QUESTION ITS HARD (the top is an example I don’t understand it)

see below

Step-by-step explanation:

1. 39

2.96

3.85

4.56.

Here's how to do it. so assuming you know one digit multiplication you would want to do something like this

17

x 5

you would start by multiplying 7x5 since those are the first two numbers, then you would get 35, you would carry the 3 to the other side and put the 5 below like this.

3

17

x 5

5

Then after that you would multiply 5x1 since those are the next two numbers and since anything multiplied by a 1 is the same number it would be 5 still, since we have a 3 left over we would add it to the 5 and get 8. Then adding that to the bottom you would get 86.

17

x 5

85

the answer is (4,3)

since the rule for r0, 90º is (-y,x) and it was already applied to form the image, all you have to do is reverse the answer using this formula.

because linear equations are a lot simpler than quadratics equations, and linear equations formula is a lot easier to memorize. that's why i think they're harder.
