Answer: y-axis

Step-by-step explanation:

The equation of the line of reflection is the perpendicular bisector of the segment that connects a point on the preimage and the corresponding point on the image.

For this, we'll consider A(-1, -1) and A'(1, -1).

The equation of this line is clearly y = -1, and its midpoint is (0, -1).

This means the line of reflection will be a vertical line passing through (0, -1), which is the line x = 0, or the y-axis

Hello there! :)

Answer:

\boxed{b>8}\checkmark

<h2><u><em>*****The answer should have a GREATER THAN SIGN AND POSITIVE TOO!*****</em></u></h2>

Step-by-step explanation:

Distributive property: a(b+c)=ab+ac

PEMDAS

Order of operations

Parenthesis

Exponent

Multiply

Divide

Add

Subtract

Left/Right

First, you add by 4 from both sides of an equation.

b-4+4>4+4

Then, you add numbers from left/right.

4+4=8

\boxed{b>8}, which is our final answer.

Hope this helps you!

Have a nice day! :)

:D

Assoli18 [71]

The guy ran at a speed of 8.07783 MPH

Here's how I got my answer:

1 km/hr. = 0.621371

So, if you do 0.621371 * 13 you will get your answer: 8.07783 MPH

If US=52, ST=30, UT=40, VW=27, and XW=36, find the perimeter of ΔVWX. Round your answer to the nearest tenth if necessary. Figur
Ierofanga [76]

Answer:

The perimeter is 109.8

Step-by-step explanation:

As we can see here, the angles of the triangles are congruent so we can say that both triangles are congruent

When two triangles are congruent, the ratio of their corresponding sides are equal

So we can get the scale factor here by looking at the sides facing each specific angle in both triangles

In the bigger triangle,

The side facing 34 degrees has a length of 30

In the smaller triangle,

The side facing 34 degree has a length of 27

So the scale factor to get the smaller from the bigger is 27/30 = 9/10 or 0.9

Likewise the side facing 51 degrees in the bigger is 40 while for the smaller, it is 36

So the ratio still stands at 36/40 = 9/10 or 0.9

In essence, the smaller triangle will have a perimeter that is 0.9 times that of the bigger

The perimeter of the bigger is simply the sum of the side lengths

We have this as;

(52 + 30 + 40) = 122

so that of the smaller would be;

122 * 0.9 = 109.8
