a. CPCTC is your answer

CPCTC means that "Congruent Parts of a Congruent Triangle(s) are Congruent"

If ΔBRM ≅ ΔKYZ (given), then every part inside the triangle is ≅ with the corresponding side.
So, for example Line BR will be ≅  with Line KY, etc

hope this helps

In 2007, there were more than 8.14 million cars for sale. The number of cars then decreased by 23% per year. Write an exponentia
tatuchka [14]

Answer:

In 2013 there were approximately 2.2 million cars for sale.

Step-by-step explanation:

Since the number of cars is decreasing by 23% per year, it is a decay model. This types of decay can be expressed in the following expression:

cars(x) = cars(2007)*(1 - 0.23)^{x - 2007}

Where x is the year, cars(2007) is the number of cars in 2007. Applying this data we have:

cars(x) = 8.14*(0.77)^{x - 2007}

If we want to know the number of cars in 2013, we need to apply that value to x and solve the expression.

cars(2013) = 8.14*(0.77)^{2013 - 2007}\\cars(2013) = 8.14*(0.77)^{5} = 2.20332

In 2013 there were approximately 2.2 million cars for sale.

Is 12.89 irrational
STatiana [176]

No.  It's the ratio of  1,289  to  100 .

Also, it can be written as a fraction with whole numbers
on top and bottom, like this:    1289 / 100 .

Also, it can be written down on paper completely, using
digits and a decimal point or fraction bar.  (You did that.)

Any one of these three facts makes it a rational number.

The decimal expansion of all rationals will be
aleksklad [387]

Answer:

I'm pretty sure they either terminate after so many digits (end) or repeat a certain pattern of numbers.

Step-by-step explanation:

The first will look like this: 432.2340

The second would look like this: 324.234234234... ("234" would keep repeating over and over and over. And can be any sequence of #'s)

The point ( -3, 15 ) undergoes a translation of 9 units right and 10 units down. What are 5he coordinates of the new point.​
Ipatiy [6.2K]

A point is set up like (x,y)

Since horizontal movement is movement in the x-axis, the x part of the point would change.

Since horizontal changes appear as the opposite inside the parentheses, 9 units right would be -9

-3-9= -12

A change up or down is a change in the y-axis. So, 10 units down would be 15-10=5

So, the new point is (-12,5)
