Reflection across y=x is a special case transformation

$(x,y) \rightarrow (y,x)$

The original triangle has vertices A(-5,1), B(-4,3), C(-2,1), D(-3,-1) so the transformed triangle has vertices

A'(1,-5), B'(3,-4), C'(1,-2), D'(-1,-3)

Choice A'(1,-5)

Cooper is studying two fractions that are both less than 1. The first fraction has a denominator of 4 and rounds to 1. The secon

MrRa [10]

Answer: The answer is $\dfrac{1}{2}.$

Step-by-step explanation: Given that Cooper is studying two fractions and both are less than 1. The first fraction has a denominator of 4 and rounds to 1.

So, let the first fraction be

$F-f=\dfrac{3}{4}=0.75,$

and surely it will rounds to 1.

Also, the second fraction has a denominator of 6 and the same numerator as the first fraction.

Therefore, the second fraction will be

$F_s=\dfrac{3}{6}=\dfrac{1}{2}.$

Thus, the second fraction will be closest to $\dfrac{1}{2}.$

What is (-2) (3 4/7)

bulgar [2K]

The correct answer is $-7\frac{1}{7}$ .

In order to find this, we need to multiply the -2 by both parts of the second term and then simplify.

-2* 3 = -6

-2 * $\frac{4}{7} = \frac{-8}{7} or -1\frac{1}{7}$

Now we need to combine the two

-6 + $-1\frac{1}{7} = -7\frac{1}{7}$

There are 100 tiles in a word game, and 2 of the tiles are blank. Kiera draws 6 tiles, and none of them are blank.

Kay [80]

Answer:

$\frac{1}{47}$ or around 2%

Step-by-step explanation:

So we need to see how many tiles are left.

100 - 6 = 94

So we have 94 tiles. 2 of them are blank, so the chance of one being blank is:

2 / 94 which is $\frac{1}{47}$

And that is our answer! Hopefully this helps, have a nice day :D
