Answer:

The firston one is a scale factor of two and the second one is a scale factor of three.

Step-by-step explanation:

You just look at the coordinates. (1,1):(2,2) and (4,0):(8,0) and then for the second one (-1,0):(-3,0) and (3,2):(9,6).

1x2=2

4x2=8

-1x3=-3

3x3=9

2x3=6

What inequality is shown in the graph? Please help and thanks in advance!

konstantin123 [22]

Greater than because the line is dashed and the shaded region is in the positive or less negative numbers area. Greater than or equal would be the same but with a solid line.

Triangle ABC has vertices at A(−3, 4), B(4, −2), C(8, 3). The triangle is translated 4 units down and 3 units left. Which rule r

Option C: $(x, y) \rightarrow(x-3, y-4) ; (5,-1)$ is the coordinates of C after translation.

Explanation:

The triangle ABC has vertices at A(−3, 4), B(4, −2), C(8, 3).

Also, given that the triangle is translated 4 units down and 3 units left.

We need to determine the coordinates of the vertex C after translation.

The triangle is shifted 4 units down means subtracting 4 units from the y - coordinate of the graph.

Thus, it can be written as $y-4$

Also, the triangle is shifted 3 units left means subtracting 3 units from the x - coordinate of the graph.

Thus, it can be written as $x-3$

Thus, the translation is given by

$(x, y) \rightarrow(x-3, y-4)$

The vertices of C after translation can be determined by

$(8, 3) \rightarrow(8-3, 3-4)\implies (5,-1)$

Thus, $(x, y) \rightarrow(x-3, y-4) ; (5,-1)$ is the coordinates of C after translation.

Hence, Option C is the correct answer.

ΔEFG ~ ΔLMN. Find the similarity ratio of ΔEFG to ΔLMN.

Basile [38]

Answer:

Step-by-step explanation:

Since the triangles are similar then the ratios of corresponding sides are equal, that is

$\frac{FG}{MN}$ = $\frac{4}{2}$ = $\frac{2}{1}$

Thus the ratio of Δ EFG to Δ LMN = 2 : 1 → C
