Answer:
x = 2
y = 6
Step-by-step explanation:
y= 6x - 6
-3x- 3y= -24
to find the value of x:
- 3x - 3 (6x - 6)= -24
- 3x - 18x + 18= -24
-21x + 18 = -24
-21x= -42
<u>x = 2</u>
Now, to find the value of y:
(substitute x into the equation)
y = 6 x - 6
y = 6 (2) - 6
y = 12 - 6
<u>y = 6</u>
Answer: Y and Y'' are congruent after the translation, but not after the dilation.
Step-by-step explanation:
We know that we generally prefer rigid transformations if want to create congruent images.
There are three basic kinds of rigid transformations:
1) rotation 2) reflection 3) translation
So, they all create congruent images.
But a dilation does not create congruent images because it creates an image of similar same shape as the original but not the same size.
Given : Triangle XYZ is translated and then dilated by a scale factor of 4 centered at the origin.
Then, the correct option is "Y and Y'' are congruent after the translation, but not after the dilation."
Answer:
a series of numbers or quantities in geometric progression.
Step-by-step explanation:
If a sample consists of 1900 scores from sample no. 476th will be above the first quartile.
<h3>What are mean, median, and mode?</h3>
The three main methods for identifying the average value of a set of integers are mean, median, and mode.
Adding the numbers together and dividing the result by the total number of numbers in the list yields the arithmetic mean.
The middle value in a list that is arranged from smallest to greatest is called the median.
The value that appears the most frequently on the list is the mode.
Given a sample consisting of 1900 scores.
∴ The no. of samples that would be above quartile is the next sample from (1/4)th of 1900 which is,
= (1/4)×1900 + 1.
= 475 + 1.
= 476.
So from sample no. 476th will be above the first quartile.
