Answer:

Shira: x = 8

Samuel: m = 0

Step-by-step explanation:

Shira's mistake was that she subtracted 2 from both sides instead of adding to on both sides.

Correct Solving:

2x - 2 = 14

Add 2 to both sides;

2x = 16

Divide both sides by 2;

x = 8

Samuel's mistake was that when he distributed -2 to 8m and 8 he put the wrong sign for -2 * 8.

Correct Solving:

-2(8m + 8) = -16

Distribute;

-16m - 16 = -16

Add 16 to both sides;

-16m = 0

Divide both sides by -16;

m = 0

The diagram represents a dilation with a center at P. If the scale factor of e dilation is K, which statement about the diagram

boyakko [2]

Answer:

C is correct. If the scale factor is greater than 1, the image is an enlargement. The segment UT could be an enlargement of the segment ST.

Step-by-step explanation:

A. If > 1, then the image of could be .

B. If 0 < < 1, then the image of could be . ( If the scale factor is between 0 and 1, the image is a reduction )

C. If > 1, then the image of could be .

D.If = 2, then the image of is itself.

A is not correct. If the scale factor is between 0 and 1, the image is a reduction.

B is not correct. If the scale factor is between 0 and 1, the image is a reduction.

C is correct. If the scale factor is greater than 1, the image is an enlargement.

D is not correct. If the scale factor is 1, the figure and the image are congruent.

Which statements can be used to prove that ABC and A’B’C are congruent?

Nadusha1986 [10]

Answer:

O A.

Step-by-step explanation:

Option A identifies two angles (sufficient for similarity) and one side, sufficient (with similarity) for congruence. The applicable congruence theorem is AAS.

Option B identifies two sides and the angle not between them. The two triangles will be congruent in that case only if the angle is opposite the longest side, which is not true in general.

Option C same deal as Option A.

Option D identifies three congruent angles, which will prove the triangles similar, but not necessarily congruent.
