Answer:
y = -9/11x - 28/11
Step-by-step explanation:
y2 - y1 / x2 - x1
4 - (-5) / -8 - 3
9/-11
= -9/11
y = -9/11x + b
4 = -9/11(-8) + b
4 = 72/11 + b
-28/11
A triangle is shown on the graph:
A coordinate plane is shown. A triangle has vertices at negative 6 comma 2, negative 5 comma 5, negative 2 comma 2.
What effect will a 90-degree clockwise rotation have on the triangle? Be sure to address how it could impact the angles, side lengths, and any congruency between the original pre-image and the image.
9514 1404 393
Answer:
the image is congruent with the original, angles and lengths are unchanged
Step-by-step explanation:
Translation, rotation, and reflection are known as "rigid transformations". Effectively, you can cut the figure from some rigid material, and move it according to any of these transformations without causing it to deform in any way.
All lengths and angles retain their measures when the figure is rotated about any point, through any angle. The rotated figure is congruent with the original.

Here, the triangle is defined in the second quadrant. Rotating it 90° clockwise will move it to the first quadrant. The transformation of coordinates is ...

Find the midpoint of the segment with the given endpoints.
(-10,- 6) and (-3,7)
Step-by-step explanation:
in essence, these 2 points are the Hypotenuse of a right-angled triangle. the legs are the coordinate differences between the 2 points creating the 3rd point of that triangle at (-10, 7) : the x coordinate of one point, and the y coordinate of the other.
now, we are looking for the midpoint. this midpoint cuts the original line/hypotenuse in half creating a scaling factor of 1/2.
when we create now a similar triangle based on that "half- Hypotenuse", we need to use the same scaling factor also on the legs (the coordinate differences).
so, when we cut the coordinate differences also in half, we get the coordinates for the midpoint on the main line.
xm, ym are the coordinates of the midpoint.
xm = (x1 + x2)/2 = (-10-3)/2 = -13/2 = -6.5
ym = (y1 + y2)/2 = (-6+7)/2 = 1/2 = 0.5
so, the midpoint is (-6.5, 0.5)
In a survey that James conducted of the students in his school, he determined that 3 out of 8 students chose basketball as their favorite sport. How many students choose basketball as their favorite sport if James surveys 240 students?
Answer:
90 students
Step-by-step explanation:
Let u be 1 unit.
8u = 240
u = 240÷8
= 30
3u = 30×3

Anna spends one- fifth of her monthly paycheck on books. If she spends $50 per month,what is her monthly paycheck
Answer:
$250
Step-by-step explanation:
Reverse division is multiplication. So one fifth of 50 is ?/5=50. Now reverse this to 50*5=?. This should come out to 250, because you can leave off the zero, and do 5*5, which equals 25, and add the zero back in you get 250. So your answer is $250.

The pattern of Jordan is that, she goes up by 1 , each time.
It is given that Jordan counts 53 ducks on a pond and then she counts 3 more by following a same pattern each time.
What is the pattern that she follows ?
What will be the value if we add 1 for 4 times.
The value will be 4.
The numbers Jordan counts are
50, 51 , 52 , 53 , 54 , 55 , 56 , 57 , 58 , 59, 60
If we check
51 - 50 = 1

.
60-59 = 1
and so on.
Every time we get a difference of 1 count.
Thus , the pattern followed by Jordan is that, she goes up by 1 , each time.

Which of the following does not represent a statistical question?
A. How tall are the students in my class?
B. How many hours per week do you practice sports?
C. How much do the students on the football team weigh?
Answer:
B
Step-by-step explanation:
Because "How Tall are the students in my class?" and "How much do the students oon the team weigh,?" can vary. If you ask a question about one person, it is not a statistical question because the answer cant vary.
An answer will vary with 2 or more things.
Hope I helped.
How many hours per week do you practice sports? does not represent a statistical question because it asks for a fixed quantity, i.e., the number of hours per week someone practices sports, which does not involve variability or differences among data.
What is Statistics?Statistics is the discipline that concerns the collection, organization, analysis, interpretation, and presentation of data.
A statistical question is a question that can be answered through data analysis and involves variability or differences among data.
It usually requires collecting data from a sample or population, organizing and summarizing the data, and drawing conclusions from the results.
How tall are the students in my class and How much do the students on the football team weigh represent statistical questions because they involve collecting data on a characteristic or variable of a population, such as height or weight.
These questions can be answered through data analysis and provide information on the variability or distribution of the characteristic in the population.
Hence, Option B does not represent a statistical question because it asks for a fixed quantity, i.e., the number of hours per week someone practices sports, which does not involve variability or differences among data.

Anna drives her car at a speed of = 70 kmph
To Find:
How much distance will she cover in 3 hours 30 minutes.
Solution:
We'll use here the formula of Speed,then plug the values which are given.
Speed = Distance/Time
Speed = 70 kmphDistance = 3 hr 3 mins = 7/2 hrs70 = D/7/2
7/2*70 = Distance

If sin x=0.96, find tan x
Step-by-step explanation:
sin x= P/H
sin x = 0.96 = 96/100 = 24/25.
Let the ratio of the sides be x.
B²=H²-P²
B²=(25x)²-(24x)²
B²=625x²-576x²
B²=49x²
B=√49x²
B= 7x.
cos x = 7x/25x = 7/25.
therefore, tan x = sin x / cos x = (24/25)/(7/25) = 24/25×25/7 = 24/7 .

Sonya buys a baseball jersey for her brother on sale for 20% off. If the price she paid was $6 lower than the regular price, what was the original price of the jersey?
Answer:
30
Step-by-step explanation:
6x5
The original price of the jersey is $ 30
What is Percentage?
A percentage is a number or ratio expressed as a fraction of 100. It is often denoted using the percent sign, %
Given data ,
Let the original price of the jersey be = $ x
The percentage discount on the original price = 20 %
The difference between the original price and the discounted price = $ 6
So ,
By the percentage equation ,
Percentage discount on the original price = difference between the original price and the discounted price
And ,
( 20 / 100 ) of original price = $ 6
On simplifying the equation , we get
( 20/100 ) x = 6
( 1/5 ) x = 6
Multiply by 5 on both sides , we get
x = 5 x 6
x = $ 30
So , the original price of the jersey is $ 30 and the discounted price is $ 24
Hence , the original price of the jersey is $ 30

Write an equation in slope-intercept form
of the line that passes through the point
(-12,6) and is perpendicular to the line
X= - 3/4y -5 ( What would be my first step to put that equation into slope intercept form?) 
Hint :-
The product of slopes of two perpendicular lines is -1 . The slope intercept form of the line is [tex] y = mx + c [/tex] .The point slope form of the line is [tex] m(x-x_1) = (y-y_1) [/tex]Solution :-
The given equation to us is ,
[tex]\implies x = \dfrac{-3}{4}y - 5 [/tex]
Convert it to slope intercept form we have ,
[tex]\implies 4x =-3y -20 \\\\\implies 3y = -4x -20 \\\\\implies y =\dfrac{-4}{3}x -\dfrac{20}{3}[/tex]
On comparing to the slope intercept form of the line we have ,
