it could be C if it was 5 units to the `left` not right

Ohhh
Mehek14
  • Mehek14
but it's going to be D

Yeah I guess :P

I used point B (-3,-1) 5 units to the right (2,-1) rotation 180 rule (-x,-y) B'(-2,1)
Mehek14
  • Mehek14
and that matches the graph so D is correct

the angles with the same number of curves are corresponding

Which set of transformations has been performed on triangle PQR to form triangle P'Q'R'? Dilation by a scale factor of fraction 1 over 2 followed by reflection about the x-axis Dilation by a scale factor of 2 followed by reflection about the x-axis Dilation by a scale factor of fraction 1 over 2 followed by reflection about the y-axis Dilation by a scale factor of 2 followed by reflection about the y-axis https://gyazo.com/98150d5056ac2a00f3ca3873833050b9
Mehek14
  • Mehek14
dilation is 1/2 because the new image became smaller
Mehek14
  • Mehek14
and it was reflected over the x axis
Mehek14
  • Mehek14
so A

I really dont get this o-o there's no numbers ;-;
anonymous
  • anonymous
Maybe A?
Mehek14
  • Mehek14
not similar im not sure about this question
Mehek14
  • Mehek14
i would probably go with D but im not 100% sure

*o* TWO QUESTIONS LEFT YESSSS

A student writes an incorrect step while checking if the sum of the measures of the two remote interior angles of triangle ABC below is equal to the measure of the exterior angle. Step 1: m∠x + m∠y + m∠z = 90 degrees (sum of adjacent angles) Step 2: m∠w + m∠z = 180 degrees (supplementary angles) Step 3: Therefore, m∠x + m∠y + m∠z = m∠w + m∠z Step 4: So, m∠x + m∠y = m∠w In which step did the student first make a mistake and how can it be corrected? Step 1; it should be m∠x + m∠y + m∠z = 180 degrees (sum of angles of a triangle) Step 1; it should be m∠x + m∠y + m∠z = 180 degrees (corresponding angles) Step 2; it should be m∠w + m∠z = 90 degrees (supplementary angles) Step 2; it should be m∠w + m∠z = 90 degrees (adjacent angles) https://gyazo.com/8fc7189cdfc7287eba30b124d157165a
