- A whole number that can be divided evenly by numbers other than 1 or itself. Example: 9 can be divided evenly by 3 (as well as 1 and 9), so 9 is acomposite number. But 7 cannot be divided evenly (except by 1 and 7), so is NOT a composite number (it is a prime number).

Reflect D(3,3) E(0,5) and F(-2,2) on the x axis and then lable them D' E' and F'

Crank

Answer: D' is at (-3, 3). E' is at (0,5). F' is at (2,2).

Step-by-step explanation: D gets reflected, so y used to be 3 so you flip it and it turns into -3. E is already on the x-axis so I don’t think it can be reflected over the x-axis. F’s y-axis is -2 so when it gets reflected, it turns into 2.
