Hey there! I'm happy to help!
We see that all of our y-values go negative and our x-values stay the same. It isn't a rotation because then our x-values will switch, but they haven't switched in our problem, so A and D are incorrect.
Reflecting over the line y=x is just reflecting over a diagonal line, and that will switch the x-value as well.
The correct answer is B. reflect over the x-axis. All of the x-values stay the same here, but the y-values are all on the other side of the x-axis, so they are all negative now, and this matches the change we see with our points.
Have a wonderful day and keep on learning! :D
Answer:
32
Step-by-step explanation:
a=bh
so if you have the area and base you can rewrite the formula as
The answer to your question is true
Answer:
c= ℝ
Step-by-step explanation:
8(c-9)=6(2c-12)-4c
Distribute left side.
8*c+8*-9=6(2c-12)-4c
8c-72=6(2c-12)-4c
Distribte right side.
8c-72=6*2c+6*-12-4c
8c-72=12c-72-4c
Combine like terms.
8c-72=8c-72
Since the two sides are exactly the same, this means that any number for c will satisfy the equation.
Therefore, c= ℝ (all real numbers)
