The vertices of a triangle are P(−3, −4), Q(3, 4), and R(−6, −3). Name the vertices of Rx = 0 (PQR).
Katyanochek1 [597]
The correct answer is <span>A) P'(3, −4), Q'(−3, 4), R'(6, −3)</span>

Rx = 0 indicates a reflection over the y-axis. 

The rule for such a transformation is:
(x, y) --> (-x, y)
which means that the x-coordinate changes sign and the y-coordinate stays the same.

Therefore:
P<span>(-3, -4) --> P'(3, -4)
Q(3, 4) --> Q'(-3, 4)
R(-6, -3)</span> --> R'(6, -3)

These points are those in option A).

What is the slope of the line that passes through the points (-4,-2) and (-4,-22)? Write your answer in simplest form.​
Anuta_ua [19.1K]

Answer:

20x  - 4 = 0

Step-by-step explanation:

\frac{y - y1 }{y2 - y1}  =  \frac{x - x1}{x2 - x1}  \\ x1 =  - 4 \\ y1 =  - 2 \\ x2 =  - 4 \\ y2 =  - 22

x2 =  - 4 \\ y2 =  - 22

What is :190% times $20,000
denis23 [38]

In this question, we would be multiplying.

In this case, you would multiply 20000 by 1.9, since 1.9 is the decimal form of 190%.

Solve:

20000 · 1.9 = 38,000‬

Answer:

38,000‬

URGENT! PLEASE HELP!
valina [46]

If your teacher is asking "which of the following can be used to prove the triangles congruent?" then I agree with your statement that it's "none of the above". We simply don't have enough information to determine if the triangles are congruent or not. If we wanted to use SAS, then we'd have to know if EB = BD was true. If we wanted ASA, then we'd have to know that A = C. If we wanted AAS, then we'd have to know that E = D.


In short, you have the correct answer. Nice work.
