Answer:

Here's what I get

Step-by-step explanation:

I plotted the triangles in the diagram below.

Part A

The scale factor for dilation is ½, because every coordinate has been halved.

P (8, 0) ⟶ P' (4, 0)

Q (6, 2) ⟶ Q' (3, 1)

R (-2, -4) ⟶ R' (-1, -2)

Part B

When you reflect a point (x, y) about the y-axis, the y-coordinate remains the same, but the x-coordinate gets the opposite sign. Thus,

P' (4,0) ⟶ P" (-4,0)

Q' (3,-1) ⟶ Q" (-3,-1)

R' (-1,-2) ⟶ R" (1,-2)

∆P"Q"R" has coordinates P" (-4,0), Q" (-3,-1), R"(1,-2).

Part C

∆PQR and ∆ P"Q"R" are not congruent, because corresponding sides are not equal.

What is the measure of SVT?

velikii [3]

Answer:

C) 27

Step-by-step explanation:

180-(90+63)

180-153= 27

The angle of QVR seems to be a 90 degree angle which is where I got the 90 from then I added it to the 63 and subtracted 180 since QVT is a straight angle the degree would be 180. Therefore, you add 90 and 63 then subtract 180 to get 27 degrees.

Proportional linear relationships can be represented in how many different forms

Alla [95]

Linear relationships can be represented in several different ways: a graph, an equation, or a list of points. ... We can then graph the line to find the y-intercept, and use the slope and y-intercept to write an equation of the line.
