determine the composition of transformation that would map figure ABCD to figure A"B"C"D". 1. the transformation that would map vertex B to B' isa: a transformation down and rightb: a rotation of 90° about Bc: a rotation of 360° about B
Answers
Answer:
b: a rotation of 90° about B
Explanation:
A transformation down and right of the figure look like this:
Where the figure is just translated, so the orientation of the figure is the same.
In the same way, a rotation of 360° doesn't change the figure, because it is equivalent to make a full turn of the figure.
Finally, a rotation of 90° about B looks like this:
Where each segment of the initial figure forms an angle of 90° with its corresponding segment of the reflected figure. For example, BA is perpendicular to B'A'
Therefore, the answer is b: a rotation of 90° about B.

What is the y-intercept of the trend line, to the nearest hundredth?
Answers
The y-intercept of the trend line is equal to -23.08.
How to determine the y-intercept of the trend line?In order to determine a linear equation of the trend line that models the data points contained in the table, we would have to use an Excel regression calculator (scatter plot).
In this scenario, the teams’ number of runs would be plotted on the x-axis of the scatter plot while the teams’ number of wins would be plotted on the y-axis of the scatter plot.
On the Excel worksheet, you should right click on any data point on the scatter plot, select format trend line, and then tick the box to display an equation for the trend line on the scatter plot.
From the scatter plot (see attachment) which models the relationship between data points in the table, a linear equation of the trend line is given by:
y = 0.15x - 23.08
In conclusion, a standard linear equation is given by:
y = mx + c
Where:
m represents the slope i.e 0.15.x and y are the points.c represents the y-intercept i.e -23.08.Read more on scatter plot here: brainly.com/question/28605735

The sum of six consecutive integers is -9. What are the integers?
Answers
Therefore the six consecutive integers are -4,-3,-2,-1,0,1 .
What is consecutive integer ?
Integers that follow one another are referred to as consecutive integers. They proceed in a certain order or sequence. For instance, a sequence of natural numbers are all integers. In mathematics, the term "consecutive" refers to an uninterrupted chain of events or a continuous progression, such as when integers follow one another in a sequence where each succeeding number is one more than the one before it. The mean and median are both identical in a collection of successive integers (or in numbers). x + 1 and x + 2 are two consecutive integers if x is an integer.
Here sum of six consecutive integer is -9.
Let us take the 6 consecutive numbers are,
=> x,x+1, x+2, x+3,x+4, x+5
Now sum is -9. Then ,
=> x+x+1+x+2+x+3+x+4+x+5 =-9
=> 6x + 15 = -9
=> 6x = -9-15
=> 6x = -24
=> x = -24/6
=> x= -4
Then 6 integers are ,
=> -4,-3,-2,-1,0,1
Therefore the six consecutive integers are -4,-3,-2,-1,0,1 .

From the problem, we have an expression :
[tex](50k^3+10k^2-35k-7)\div(5k-4)[/tex]The divisor is (5k - 4)
Step 1 :
Divide the 1st term by the first term of the divisor.

Step 2 :
Multiply the result to the divisor :

Subtract the result from the polynomial :
[tex](50k^3+10k^2-35k-7)-(50k^3-40k^2)=50k^2-35k-7[/tex]Now we have the polynomial :

Which equation represents a line which is perpendicular to the line y - 6x = -3? Submit Answer Oy= 6x +3 Oy= 1/6x +4 O y= - 1/6x + 8 O y = -6x + 2
Answers
When we have two perpendicular lines their slopes are opposite and inverse.
In this case, we have the equation of the line:
y-6x= -3
Let's solve for y and arrange this equation to make it look like the general form of a linear equation: y=mx+b, where m is the slope of the line.
y-6x= -3
y-6x+6x= -3+6x
y= 6x-3
As we can see, the number that is multiplying the x variable in our equation is 6, the slope of this line is 6.
As mentioned, a perpendicular line to the line y= 6x-3 would have a slope opposite and inverse, then the slope of the line perpendicular to the first line (m2) would be:
[tex]m2=-\frac{1}{6}[/tex]from the options that we have, we can see that the only line that has a slope of -1/6 is the line y= -1/6+8, so that is the right option.

Explanation
The question wants us to solve the simultaneous equation
4y - 3x = -16
8x - 4y = 24
Adding the two equations, we have,
4y - 3x + 8x - 4y = -16 + 24
5x = 8
Divide both sides by 5
(5x/5) = (8/5)
x = 1.6
If x = 1.6,
8 (1.6) - 4y = 24
12.8 - 4y = 24
-4y = 24 - 12.8
-4y = 11.2
y = -2.8
Hope this Helps!!!
