Choice A is a trinomial, but it doesn't have a constant term
Choice D is the only other trinomial. This has a constant term, which is 6. The constant is the term without any variables attached to it.
Answer: Choice D
Answer: D. [tex]x+7y+6[/tex]
Step-by-step explanation:
We know that a trinomial is a polynomial with three terms.
From all the given options, only option A. [tex]x^3+12x^2+x[/tex] and option D. [tex]x+7y+6[/tex] are trinomials having three terms .
But option A [tex]x^3+12x^2+x[/tex] does not have any constant term .
On the other hand option D. [tex]x+7y+6[/tex] has a constant term of 6.
Therefore, the option D. [tex]x+7y+6[/tex] represents a trinomial with a constant term.

∆ABC is transformed with the center of dilation at the origin.
Pre-image: ∆ABC with vertices A(2, 5), B(6, 10), C(9, −1)
Image: ∆A'B'C' with vertices A' (0.5, 1.25), B' (1.5, 2.5), C' (2.25, −0.25)
What is the scale factor of the dilation that maps the pre-image to the image?
Answer:
1/4
Step-by-step explanation:
We are to find the scale factor of the dilation that maps the pre-image of triangle ABC with vertices A(2, 5), B(6, 10) and C(9, −1) to the image triangle A'B'C' with vertices A' (0.5, 1.25), B' (1.5, 2.5), C' (2.25, −0.25).
Center of dilation is at the origin.
To find the scale factor, we will divide the corresponding vertices of the image and pre-image.
A(2, 5) ---> A' (0.5, 1.25) = [tex]\frac{0.5}{2} , \frac{1.25}{5}=(\frac{1}{4} , \frac{1}{4})[/tex]
B(6, 10) ---> B' (1.5, 2.5) = [tex]\frac{1.5}{6} , \frac{2.5}{10}=(\frac{1}{4} , \frac{1}{4})[/tex]
C(9, −1) ---> C' (2.25, −0.25) = [tex]\frac{2.25}{9} , \frac{-0.25}{-1}=(\frac{1}{4} , \frac{1}{4})[/tex]
Therefore, the scale factor of the dilation is 1/4.
The scale factor of the dilation that maps triangle ABC to triangle A'B'C' is determined by calculating the ratio of the coordinates of corresponding vertices. The scale factor for this transformation is 0.25.
The student is asking how to find the scale factor of a dilation when given the coordinates of the vertices of a triangle before and after the transformation. To determine the scale factor, you need to compare the corresponding sides or coordinates of the pre-image and the image. Below is the step-by-step explanation:
Identify corresponding vertices between the pre-imageTherefore, the scale factor for the dilation that maps the pre-image to the image is 0.25.

6. Below is a graph that represents the total profits for a third month. Write the equation of the line that represents this graph.
Answer:
y= -2/3x(m) +400(b)
Step-by-step explanation:
1.2x + 3y = 1200
3y = -2x + 1200
y = (-2x/3)x + 1200/3
the slope is -2/3x the y intercept is 400
2.I would plot the ordered pair (0, 400) on the coordinate plane. Then to find the other ordered pair you would use the slope (-2, 3). You should go two spaces to the right of (0, 400) and then three spaces down. After this your slope look like (-2, 397)
3.the function t(x) gives the number of tablets, given that x smart-phones have been sold/produced
t(x) = (-2/3)x + 400
Suppose in the next month, the total profit on smart phone cases and tablet cases is $1,500. The profit amounts are the same, $2 for smart phone case and $3 for the tablet case. In a paragraph of at least three sentences, explain how the graphs of the functions for the two months are the same and how they are different. Be sure to use complete sentences.
They would be similar because the slope would stay the same. The slope would stay the same, because the prices remain the same. They would be different because their y intercept would change

What is the distance between the points (–6, –10) and (2, 5)?
Answer:
17
Step-by-step explanation:
To find the distance between two points, we use the formula
d =sqrt( (x2-x1)^2 + (y2-y1)^2)
d= sqrt((2--6)^2+(5--10)^2 )
d= sqrt((2+6)^2+(5+10)^2 )
d = sqrt(8^2 + 15^2)
d = sqrt(64+225)
d =sqrt(289)
d =17

The mean and standard deviation for number of robberies in the U.S. from 2000 to 2015 are x̄ = 354,718 and sx = 28,803. The mean and standard deviation for number of assaults in the U.S. for the same time period are ȳ = 774,140 and sy = 44,910. The correlation coefficient is r = 0.84. Find the equation for the least-squares regression line for number of assaults compared with number of robberies. ŷ = 309,552.15 + 1.31x ŷ = 1.31 + 309,552.15x ŷ = 546,641.84 + 0.64x ŷ = 0.64 + 546,641.84x Unable to determine the equation
Answer:
[tex]\hat{y}=309,552.15 + 1.31x[/tex]
Step-by-step explanation:
The equation for the least-squares regression is,
[tex]\hat{y}=a+bx[/tex]
where b is the slope and a is the intercept.
They can be found out by,
[tex]b=r\cdot \dfrac{SD_y}{SD_x},\\\\a=\overline{y}-b\overline{x}[/tex]
where,
r = correlation coefficient = 0.84
[tex]SD_y[/tex] = standard deviation of y = 44,910
[tex]SD_x[/tex] = standard deviation of x = 28,803
[tex]\overline{y}[/tex] = mean of y = 774,140
[tex]\overline{x}[/tex] = mean of x = 354,718
Putting the values,
[tex]b=0.84\cdot \dfrac{44910}{28803}=1.309\approx 1.31[/tex]
[tex]a=774140-(1.31\times 354718)\approx 309,552.15[/tex]

A collection of 36 shirts and 42 jackets contains 842 buttons. A collection of 66 shirts and 77 jackets contains 137 buttons. Each shirt has the same number of buttons, and each jacket has the same number of buttons. How many buttons are there in a Fiona's Fashion shirt, and how many buttons are there in a jacket?
Answer:
Step-by-step explanation:
Let x represent the number of buttons on shirts and y represent the number of buttons on jackets.
If 36 shirts and 42 jackets contain 842 buttons. This implies:
36x + 42y = 842 (1)
If 66 shirts and 77 jackets contain 137 buttons. This implies:
66x + 77y = 137 (2)
If you take the first equation: 36x + 42y = 842 and isolate the x, then you will have x = (842 - 42y) / 36
If you substitute x into the second equation:
66((842-42y)/36) + 77y = 137
→ 11(842-42y)/6 + 77y = 137
→ 11(842-42y) + 6(77y) = 137(6)
→ 9262 - 462y + 462y = 822
→ 9262 = 822 which reveals that the equations do not have a solution

John states that by ASA.
Mary states that by AAS.
Phillip states that the triangles are not congruent.
Which student is correct? why?
MY ANSWER:
Phillip is correct. XY=/ AC. (But i have another guess/answer)
No student is right, These triangles arent congruent but these triangles are to different triangles. We can see this with XY/AC. (But doesnt that just mean phillip is correct?) HELP!
Answer: Phillip is correct. The triangles are not congruent.
How do we know this? Because triangle ABC has the 15 inch side between the two angles 50 and 60 degrees. The other triangle must have the same set up (just with different letters XYZ). This isn't the case. The 15 inch side for triangle XYZ is between the 50 and 70 degree angle.
This mismatch means we cannot use the "S" in the ASA or AAS simply because we don't have a proper corresponding pair of sides. If we knew AB, BC, XZ or YZ, then we might be able to use ASA or AAS.
At this point, there isn't enough information. So that means John and Mary are incorrect, leaving Phillip to be correct by default.
Note: Phillip may be wrong and the triangles could be congruent, but again, we don't have enough info. If there was an answer choice simply saying "there isn't enough info to say either if the triangles are congruent or not", then this would be the best answer. Unfortunately, it looks like this answer is missing. So what I bolded above is the next best thing.
Answer:
Phillip states that the triangles are not congruent.
Step-by-step explanation:
Assume for a second the triangles are congruent.
Then the angles are equal
<A =< X
<B= <Y
<C = <Z
Then
Triangle ABC = Triangle XYZ
from this information
AB = XY
and BC = YZ
and CA = ZX
but the only other piece of information we have is CA = 15 and XY = 15
If this is true then CA = ZX = 15 and AB = XY = 15
That would make this an isosceles triangle (AB = AC)
so angles B and C would have to be equal, but they are not.
So these two triangles cannot be congruent.
Solve the system of equations using elimination.

(3, 6)
B)
(8, 5)
C)
(7, 10)
D)

Answer: D.(5, -8)
Step-by-step explanation:
(Multiply by -1)-8x-7y=16
10x+7y=-6
2x=10
X=5
(Subsitite 5 into one) 10(5)+7y=-6
50+7y=-6
7y=-56
Y=-8
Final answer:
To solve the system using elimination, subtract the first equation from the second to find x=5, then substitute x back into one of the original equations to find y=-8. The solution is (5, -8).
Explanation:
To solve the system of equations using elimination, we look at the given pairs:
8x + 7y = -1610x + 7y = -6We can eliminate the y-variable by subtracting the first equation from the second
(10x + 7y) - (8x + 7y) = -6 - (-16)10x - 8x + 7y - 7y = -6 + 162x = 10Divide both sides by 2:
x = 5Now that we have x, we can substitute it back into either of the original equations to find y. Let's use the first equation:
8(5) + 7y = -1640 + 7y = -167y = -16 - 407y = -56Divide both sides by 7:
y = -8Therefore, the solution to the system of equations is (5, -8), which corresponds with answer choice D.
Line m contains (6,8) and (-1,2). Line n contains (-1,5) and (5,y). What is the value of y if line m is perpendicular to line n
Answer:
y=-37
Step-by-step explanation:
A perpendicular line has a negative reciprocal slope to the original line. We will use the slope formula to find the slope of line m, then take the negative reciprocal for the slope of line n which will reveal the value of y.
Slope:[tex]m=\frac{y_2-y_1}{x_2-x_1}[/tex]
We substitute [tex]x_1=6\\y_1=8[/tex] and [tex]x_2=-1\\y_2=2[/tex]
[tex]m=\frac{2-8}{-1-6}[/tex]
[tex]m=\frac{2-8}{-1-6}=\frac{-6}{-7} =\frac{6}{7}[/tex]
[tex]m\neq \frac{6}{7}[/tex] for line n because it is perpendicular to it. This means we will need to change it into its negative reciprocal which is [tex]m=-\frac{7}{6}[/tex].
We will substitute [tex]m=-\frac{7}{6}[/tex] into the slope formula to find line n's coordinate value y. We will also substitute [tex]x_1=-1\\y_1=5[/tex] and [tex]x_2=5\\y_2=y[/tex] .
[tex]m=\frac{y_2-y_1}{x_2-x_1}[/tex]
[tex]-\frac{7}{6}=\frac{y-5}{5-(-1)}[/tex]
[tex]-\frac{7}{6}=\frac{y-5}{6)}[/tex]
[tex]6(-\frac{7}{6})=y-5[/tex]
[tex]-42+5=y-5+5[/tex]
[tex]-37=y[/tex]
The value of y that makes Line n perpendicular to Line m is 59/6. This is found by first calculating the slope of Line m and then finding the negative reciprocal (since perpendicular lines have negative reciprocal slopes), and using this new slope to solve for y in Line n.
Explanation:To solve this problem, we first need to understand that the slopes of two perpendicular lines are negative reciprocals of each other. This means that if Line m has a slope of a, then Line n will have a slope of -1/a.
First, let's find the slope of line m which contains the points (6,8) and (-1,2). The formula for slope is (y2-y1)/(x2-x1). This gives us (2-8)/(-1-6) = -6/-7 = 6/7.
Because line n is perpendicular to line m, its slope will be the negative reciprocal of 6/7, which is -7/6. We can then use this slope and the point (-1,5) to find the value of y when x=5 on line n. We use the equation y-y1 = m(x-x1), and substitute the values in: y - 5 = -7/6 * (5 - (-1)), which simplifies to y = -7 + 5 + 35/6 = 29/6 + 30/6 = 59/6.

Which expression helps you find the length x of a side of a rectangle that has a diagonal of 17 units and a width of 8 units?
To find the length of a rectangle given the diagonal and width, one can utilize the Pythagorean theorem. By treating the diagonal as the hypotenuse of a right triangle formed within the rectangle, we solve for 'x' (length) and get our desired result.
Explanation:To find the length (x) of the side of a rectangle given the diagonal (17 units) and the width (8 units), you can use the Pythagorean theorem, which states that in a right triangle, the square of the length of the hypotenuse is equal to the sum of the squares of the lengths of the other two sides. In the rectangle, the diagonal forms a right triangle with two sides.
In the context of this question, our hypotenuse is the diagonal, which is 17 units long. Let's denote the width as 'w' and the length we're trying to find as 'x'. With 'w' being 8 units, our scenario can be represented by the Pythagorean theorem like this: (17²) = (8²) + (x²)
In determining 'x', we can rearrange the equation to solve for 'x': x = sqrt[(17²) - (8²)]. So, when we subtract the square of 8 from the square of 17 then take the square root, we get the length of 'x'.

A store manager ordered 28 crates of mangoes.There were 36 mangoes in each crate.WHEN the mangoes were delivered, he sold the ripe mangoes and repacked the rest equally into 73 boxes.There were 12 mangoes in each box.How many ripe mangoes were sold?
Answer:
Number of ripe mangoes were sold as 132
Step-by-step explanation:
Let's assume number of rip mangoes were sold as 'x'
A store manager ordered 28 crates of mangoes
Number of crates =28
There were 36 mangoes in each crate
Number of mangoes in each crate=36
Total number of mangoes=( Number of crates)*(Number of mangoes in each crate)
Total number of mangoes is
[tex]=28\times 36[/tex]
[tex]=1008[/tex]
WHEN the mangoes were delivered
he sold the ripe mangoes and repacked the rest equally into 73 boxes
There were 12 mangoes in each box
Total number of mangoes is
[tex]=73\times 12+x[/tex]
[tex]=876+x[/tex]
now, we can set them equal
[tex]1008=876+x[/tex]
[tex]x=132[/tex]
To find the number of ripe mangoes sold, multiply the number of crates by the number of mangoes in each crate. Then, multiply the number of boxes by the number of mangoes in each box. Finally, subtract the number of mangoes repacked into boxes from the total number of mangoes delivered.
To find the number of ripe mangoes sold, we need to determine the total number of mangoes delivered and then subtract the number of mangoes repacked into boxes.
First, we find the total number of mangoes delivered by multiplying the number of crates (28) by the number of mangoes in each crate (36): 28 crates * 36 mangoes/crate = 1008 mangoes
Next, we find the number of mangoes repacked into boxes by multiplying the number of boxes (73) by the number of mangoes in each box (12): 73 boxes * 12 mangoes/box = 876 mangoes
Finally, we subtract the number of mangoes repacked into boxes from the total number of mangoes delivered to find the number of ripe mangoes sold: 1008 mangoes - 876 mangoes = 132 ripe mangoes
