What is the percent of change from 10 to 5?

NNADVOKAT [17]

Answer:

50% decrease

Step-by-step explanation:

$\dfrac{(V_2-V_1)}{|V_1|} \times 100$

$= \dfrac{(5 - 10)}{|10|} \times 100$

$= \dfrac{-5}{10} \times 100$

$= -0.5 \times 100$

$= -50\% \; \text{change}$

$= 50\% \; \text{decrease}$

Rotate angle ABC 90 degrees clockwise about the origin and then reflect over the x-axis

Lady_Fox [76]

Rotation and reflection are instances of transformation

See attachment for the new position of $\triangle ABC$

From the question, we have:

$A = (-1,1)$

$C = (-2,4)$

The rule of 90 degrees clockwise rotation is:

$(x,y) \to (y,-x)$

Using the above transformation, the new points would be

$A' = (1,1)$

$B' =(3,3)$

$C' = (4,2)$

The next transformation is reflection over the x-axis

The rule of this transformation is:

$(x,y) \to (x,-y)$

So, the new points would be:

$A" = (1,-1)$

$B" = (3,-3)$

$C" = (4,-2)$

See attachment for the new points
