Hello! Please help. <br> "Find the error &amp; explain why it is wrong."
mixas84 [53]

Answer: Step E

Step-by-step explanation:

The error is in the last step. In Step D, we see that we're supposed to subtract the second part from the first part. We also see we have the terms 2x-8 in the numerator on the right. Since we're subtracting, the expression should actually be -2x +8. 3 -2x +8 should be -2x +11 which is not the numerator in Step E so the last step is wrong.

Translate Δ A B C 6 units horizontally. How are the values in the ordered pairs affected by the translation?
snow_tiger [21]

Answer:

The x-coordinates are translated 6 units to the left or right while the y-coordinates are not affected.

Step-by-step explanation:

The given triangle has vertices at A(-4,1), B(-2,1) and C(-2,4)

The transformation rule for a horizontal translation by k units is

(x,y)\to (x\pm k,y)

In this case we have k=6

A(-4,1)\to A'(-4\pm6,1)

B(-2,1)\to B'(-2\pm6,1)

C(-2,4)\to C'(-2\pm6,4)

Therefore the x-coordinates are translated 6 units to the left or right while the y-coordinates are not affected.
