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 A) P'(3, −4), Q'(−3, 4), R'(6, −3)

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(-3, -4) --> P'(3, -4)
Q(3, 4) --> Q'(-3, 4)
R(-6, -3) --> R'(6, -3)

These points are those in option A).

Choose two angles that are each separately alternate exterior angles with 412.

Alborosie

Answer:

∠2 and ∠5

Step-by-step explanation:

we know that

Alternate Exterior Angles are a pair of angles on the outer side of each of those two lines but on opposite sides of the transversal

In this problem

∠12 and ∠2 are alternate exterior angles

∠12 and ∠5 are alternate exterior angles

therefore

∠2 and ∠5 are each separately alternate exterior angles with ∠12

I don’t know how you do 17.1 divided by 0.9.

andreyandreev [35.5K]

The answer is 19

work :

1-multiply the numbers by a submultiple of 10 to remove the decimal points.
$17.1 \times 10 = 171 \\ \\ 0.9 \times 10 = 9$

2-

now do the division :
$171 \div 9 = 19$

so the answer is 19

note: there is no need to get it back to decimal number unless you multiply just one of the numbers or multiply the numbers with different submultiples of 10

good luck

You are taking a multiple-choice test that has eight questions. each of the questions has three answer choices, with one correct

sukhopar [10]

Alright, so there are three answers. Start with 3, and for each question you answer, you can select three more, so it's 3*3 for two questions and so on, resulting in 3^8= 6561

This is assuming you mean how many ways can you answer the test, not the question
