Answer:
Sam's thinking was incorrect.
On number first we have to move 10 units from 0 in positive direction after that negative sign means move in left direction.
But we have 2 negative signs so we need to move 6 units more on positive or right direct as shown below.
Step-by-step explanation:

Answer:
(- 1, - 1 )
Step-by-step explanation:
Since the dilatation is centred at the origin, then multiply the coordinates of the original point by the scale factor, that is
(- 3, - 3 ) → (
× - 3, × - 3 ) → (- 1, - 1 )
We notice that the upper trapezoid is symmetric to the lower one & the line of symmetry should be a horizontal line (mirror line) where any point of the upper vertices should be at equal distance (perpendicular) with the related vertices of the lower one from this horizontal line:
Note that QQ" =4 units, Hence the line of symmetry is the perpendicular to QQ' at 2 units
Answer:
2, 6, and 7
Step-by-step explanation:
3n is by itself because theres no other numbers that have the letter n.
6m and -11m are like terms bcs they both have the letter m (variable)
-3 and -18 are both like terms bcs they are both just numbers (or constants whatever)
so you would choose options 2, 6, and 7! hope this helps! :)
