Do the values in the table represent a proportional relationship?
x 1 2 3 4
y 2.5 5 7.5 10
Select from the drop-down menu to correctly complete the statement.
All of the y-values a constant multiple of the corresponding x-values, so the relationship
Answers
Answer:
yes every values are increasing constantly by 2.5
Answer:
Step-by-step explanation:
Note that for each unit increase in x, y increases by 2.5. The constant of proportionality is therefore 2.5:
y = 2.5x
All of the y-values are a constant multiple of the corresponding x-values, so the relationship is a proportional one.

Mrs.Rose received a 35% discount on her cell phone. The price of her cell phone came out to be $180. How much was the original price of her cell phone?
Answers
Answer:
The original price of the cell phone is $514.29
Step-by-step explanation:
The answer is $514.29 because the equation to find the answer is :
Let x = the original price of the cell phone
$180 = Price after discount
So, 180 = x * 35/100
Multiply by its reciprocal on both sides so
180 (100/35) = x
18000/35 = x
514.29 = x
So the original price of the cell phone is $514.29

D - 320
Step-by-step explanation:
You divide 48 by 15% and it equals 320 which is the starting value. To check your answer you take 15% out of 320 which gives you 48. Letter C is incorrect because 15% of 150 is 22.5. A and B are not correct because A is lower than the amount spent and there is no way that B would work because 15% of 55.20 is 8.28. Good luck with your math test!

Begin with a concrete example: What is 5% of n?
To answer this, rewrite 5% as 0.05 and multiply n by this 0.05.
Now revert to m% of n: Divide m% by 100% and multiply n by this m/100.

Answer:
y=3/4x
Step-by-step explanation:
From the origin (0,0) count the rise to the next point (3) and then the run (4) leaving you with 3/4 as your slope.
so, we should make an equation that follows:
y = mx + b
b = y intercept, which is 0 because it connects at the origin.
m is the slope, which is rise/run.
we find a point at ( 0.7 , 0.5 ).
the rise is 0.5, and the run is 0.7, so we do
0.5/0.7
and we get 0.714285714285714, which we can round to 0.7143 for the m.
we have everything we need.
so,
y=0.7143x
(the b is 0, so we don’t have anything else to add).

Hi!
It seems like you have two answers in the boxes already, but it is not correct.
Firstly, you cannot tell mean from a box plot. The first box should be moved to the last category.
Your second boxes seems to be correct though.
As far as the remaining boxes, I can help with those too!
Median: The median is identifiable in a box plot, as the line in the boxes themselves are the medians. The medians do line up, therefore they belong in category 1.
Minimum: This is the value that is the least. We can tell this from a box plot, by looking at the most left line, or the "whiskers", as some teachers call them. For our box plots, the minimum is 4. They line up exactly. Therefore, this box should go in the first category.
IQR: The IQR "measures the spread of the middle half of your data". In these box plots, the IQR is different. Therefore, it belongs in the second category.
Mode: This is the value that appears most often in a set of data values. You cannot tell this from a box plot. Therefore, it belongs in the last category.

A holiday meal cost $12.50 a person plus a delivery fee of 30$. Which equation is right?
1. y=30+12.50x
2. y= 12.50+30
3. 12.50x=30
4. y=12.50+30x
Answers
Answer:
1. y = 12.50x + 30
Step-by-step explanation:
A holiday meal cost $12.50 a person plus a delivery fee of 30$
Let x = number of people ordering a meal and y = total cost
It cost 12.50 per person so the cost regarding the number of people that orders food can be represented by 12.50x.
There is also a $30 delivery fee.
So the total cost would (y) = 12.50x + 30
The answer would be 1. 12.50 and 30 just swapped places.

The vertices of triangle B'C'D' are:
B'(-1, -1/2)
C'(0, 2)
D'(1, -3/2)
What is a triangle?A triangle is a 2-D figure with three sides and three angles.
The sum of the angles is 180 degrees.
We can have an obtuse triangle, an acute triangle, or a right triangle.
We have,
To find the vertices of triangle B'C'D', which is a dilation of triangle BCD with center at the origin and a scale factor of 1/4,
We can follow these steps:
Find the coordinates of the centroid of triangle BCD.
The coordinates of the centroid G are:
[tex]x_G = (x_B + x_C + x_D) / 3 = (4 + 8 + 12) / 3 = 8[/tex]
[tex]y_G = (y_B + y_C + y_D) / 3 = (4 + 14 + 0) / 3 = 6[/tex]
Translate triangle BCD so that its centroid is at the origin.
We can do this by subtracting the coordinates of the centroid from the coordinates of each vertex:
B(4, 4) → [tex]B_1(4 - 8, 4 - 6) = B_1(-4, -2)[/tex]
C(8, 14) → [tex]C_1(8 - 8, 14 - 6) = C_1(0, 8)[/tex]
D(12, 0) → [tex]D_1(12 - 8, 0 - 6) = D_1(4, -6)[/tex]
Dilate the translated triangle [tex]B_1C_1D_1[/tex] by a scale factor of 1/4.
To do this, we can multiply the coordinates of each vertex by 1/4:
[tex]B_1[/tex](-4, -2) → B'(-4 x 1/4, -2 x 1/4) = B'(-1, -1/2)
[tex]C_1[/tex](0, 8) → C'(0 x 1/4, 8 x 1/4) = C'(0, 2)
[tex]D_1[/tex](4, -6) → D'(4 x 1/4, -6 x 1/4) = D'(1, -3/2)
Therefore,
The vertices of triangle B'C'D' are:
B'(-1, -1/2)
C'(0, 2)
D'(1, -3/2)

2.1 Factoring 2d2-3d-2
The first term is, 2d2 its coefficient is 2 .
The middle term is, -3d its coefficient is -3 .
The last term, "the constant", is -2
Step-1 : Multiply the coefficient of the first term by the constant 2 • -2 = -4
Step-2 : Find two factors of -4 whose sum equals the coefficient of the middle term, which is -3 .
-4 + 1 = -3 That's it
Step-3 : Rewrite the polynomial splitting the middle term using the two factors found in step 2 above, -4 and 1
2d2 - 4d + 1d - 2
Step-4 : Add up the first 2 terms, pulling out like factors :

Step-5 : Add up the four terms of step 4 :

because you start by dividing 354 by 3 = 118, then you multiply that 118 by 4 = 472.
