Answer: The student is <u>not</u> correct
To reflect over the y axis, you use this rule
The x coordinate swaps in sign (from positive to negative, or vice versa) while the y coordinate stays the same.
So for a point like A(1,1), it should move to A ' (-1, 1) and not (-2,1) like the diagram shows.
B(3,1) should move to B ' (-3, 1)
C(1,4) should move to C ' (-1, 4)
It appears that the student applied a reflection over the y axis, and then they shifted the triangle 1 unit to the left.
Answer:
A' coordinate : ( - 18 , - 14 )
Step-by-step explanation:
since it is translated left, we will minus it from the x coordinate
-6 - 12 = -18

Answer: X = 24
Step-by-step explanation:
Move all terms to the left:
(3x + 10) - (2x - 9) - 43 = 0
Get rid of all the parenthesis:
3x + 10 - 2x - 9 - 43 = 0
Add all the numbers and all variable:
x-24 = 0
Move all terms containing x to the left and all other terms to the right:
x = 24
Answer:
200
Step-by-step explanation:
18 × 10 = 180
20 × 1 = 20
180 + 20 = 200
