That would be 3x=50-10y
Step-by-step explanation:
If 10y and 3x add up to 50 then the expression above is checking to see if 3x is the correct answer to 50. Therefore 3x= 50- 10y. Thank you for submitting this question.
a) What type of correlation is shown in diagram A?
b) What type of correlation is shown in diagram B?
c) What type of correlation is shown in diagram C?
Answer:
A = strong negative correlation
B = positive correlation
C = very weak or no correlation
Step-by-step explanation:
Scatter plot A:
A clear linear trend line could be observed having a negative slope ; the nature of the slope gives the nature of the correlation (positive or negative). Since the slope is negative then we have a negative correlation. The linear trend line is almost straight with only few points marginally missing the best fit line. Hence. We can conclude to have a strong negative correlation.
Scatter plot B :
Has a positive slope, and hence a positive correlation. The best fit line miss a few points but the linear trend of the plot is still observable. Hence, we can conclude to having a fairly strong positive correlation.
Scatter plot C :
From the graph, no linear trend can be observed and hence it is fit to say that no correlation exists between the points.

At Kirby Middle School, some students were surveyed to see which social
media app they used the most. The results are shown below.
App Number of Students
Face
8
Snap
22
Insta
20
Solve and explain how to calculate what percent of students used Snap the
most?
Answer:
Kirby Middle School
The percentage of students who used Snap the most is given as:
= 44%
Step-by-step explanation:
a) Data and Calculations:
App Number of Students
Face 8
Snap 22
Insta 20
Total 50
The percentage of Snap users = Number of Snap users/Total users * 100
= 22/50 * 100 = 44%
b) This represents the proportion of all the students surveyed about the use of social media app. Since 22 students used Snap out of 50, it means that 44% of the survey sample used Snap. This is against 16% (8/50) who used Face and 40% (20/50) who used Insta.

Reflecting across the x axis is easy. Think of the x axis as a mirror. when you look in a mirror, your image is behind the mirror the same distance you are in front of the mirror. So, to reflect across the x axis, just multiply all the y values of the points by -1. For the reflection part
(-3,4) becomes (-3,-4)
(1,2) becomes (1,-2)
(-2,1) becomes (-2,-1)
Step 2 probably is a translation, but it is not clear what it is - so I cannot help you further.
If you get step 2 straight, the dilation by 3 is achieved by multiplying all the x and y values by 3.

Jordan uses a recipe to make yogurt putty. He buys a bag of cornstarch containing 128 servings that are 1/8 cups each. He needs 2 1/4 cups for each batch of yogurt putty. About how many batches can Jordan make? Due by 2:59 PM today
Answer:
6 Batches because if each batch calls for 1/3 of a cup of flour and you split 2 cups into 1/3 cups you would have 6 1/3 cups
Step-by-step explanation:
Jordan can make 7.111 batches before 3 PM today.
What is division?The division in mathematics is one kind of operation. In this process, we split the expressions or numbers into the same number of parts.
Given:
Jordan uses a recipe to make yogurt putty.
He buys a bag of cornstarch containing 128 servings that are 1/8 cups each.
He needs [tex]2\frac{1}{4}[/tex] cups for each batch of yogurt putty.
So, servings are 128 x (1/8)
= 16 cups.
To find the number of batches:
Use division,
16 / ( 9/4)
= 16 x 4/9
= 64 / 9
= 7.111
Therefore, 7.111 batches Jordan can make.

Which set of coordinates satisfies the system of equations y = x − 3 and y = -2x + 1?
Given:
The system of equations is
[tex]y=x-3[/tex] ...(i)
[tex]y=-2x+1[/tex] ...(ii)
To find:
The set of coordinates that satisfies the system of equations.
Solution:
On equating the given equations, we get
[tex]x-3=-2x+1[/tex]
[tex]x+2x=3+1[/tex]
[tex]3x=4[/tex]
Divide both sides by 3.
[tex]x=\dfrac{4}{3}[/tex]
Putting [tex]x=\dfrac{4}{3}[/tex] in (i), we get
[tex]y=\dfrac{4}{3}-3[/tex]
[tex]y=\dfrac{4-9}{3}[/tex]
[tex]y=\dfrac{-5}{3}[/tex]
Therefore, the required set of coordinates that satisfies the given system of equations is [tex]\left(\dfrac{4}{3},\dfrac{-5}{3}\right)[/tex].

If the x-value repeats and the y does not, is it a function?
Answer:
If X repeats and y does not it is not an example of a function. But if the y repeats and has two different x values that can be known as a function.
For an example ( 1 , 3) and (1, 4) thats not an example of a function because the x value is repeating but if its ( 1, 4) and (2,4) a thats
a function because no x value is repeating the x value is known as an independent value. Does that make sense?
"This relation is definitely a function because every x-value is unique and is associated with only one value of y. So for a quick summary, if you see any duplicates or repetitions in the x-values, the relation is not a function."
If an x-value in a relation repeats, the y-value must also repeat for that x-value to make the relation to be defined as a function.
For a relation to be called a function, the following holds true:
Each x-value (input) has it's own unique y-value (output).
A x-value cannot give two different y-values.
If an x-value repeats, the corresponding y-value must repeat.
Therefore, if the x-value in a relation repeats, the y-value must also repeat for that x-value for the relation to be defined as a function.
