Which expression has exactly three terms? Select all the expressions that apply.
A. 3x
B. y^3
C. xyz
D. x+y+1
E. x+y+z
F. y^3−2y^2+y−1
G. 4x^3+10x^4−7x
H. ( x+1)( y−2 )( z+5 )
Answers
The answer is expressions D, E, and G.
In algebra, a ‘term’ usually means the different parts of an expression that are separated by + and - signs.
Options A and B only have 1 term, an x or y³, so these are incorrect.
Option C has 1 term as well, ‘xyz’, because they are all multiplied together which makes it one term.
D and E both have 3 terms each, but F has 4 unique terms so this is incorrect also.
G has 3 unique terms, x³, x^4, and 7x, so this is correct.
When H is expanded, you will end up with more than 3 unique terms, so this is incorrect.

Abigail can read 180 words in one minute if she were to read 30 minutes each day how many days would it take to read 32,400 words of a book
Answers
Answer:
It would take Abigail six days to read 32,400 words of a book if she were to read 30 minutes per day.
Step-by-step explanation:
If Abigail reads 180 words per minute, and she reads 30 minutes per day, we need to multiply 180 by 30 to figure out how many words she reads per day.
180 × 30 = 5,400
Abigail reads 5,400 words per day.
Then, we divide 32,400 by 5,400 to figure out how many days it would take Abigail to read 32,400 words.
32,400 ÷ 5,400 = 6
It would take Abigail six days to read 32,400 days.

Here are the diameters of four coins: penny (1.9 cm), nickel(2.1cm), dime (1.8cm), quarter (2.4cm). A coin rolled about 33 cm in 5 rotations. Which coin is it? Use 3.14 for pi
Answers
Answer: Nickel
Step-by-step explanation:
Hi, to answer this we have to calculate the circumference of each coin:
C =π diameter.
Penny = 3.14 (1.9)= =5.96 cm
Nickel = 3.14 (2.1) =6.6 cm
Dime = 3.14 (1.8) =5.62 cm
Quarter = 3.14 (2.4) =7.53 cm
Since the coin rolled about 33cm in 5 rotations, it means that the circumference of the coin (x) multiplied by 5 is equal to the distance rolled.
5x=33
x =33/5 =6.6 cm
The coin is the nickel, because its circumference is equal to 6.6 cm.
what is the answer: -4 - 2
Answers
First change -4 - 2 to -4 + -2.
Now we can use our number line to
help us visualize what's going on.
Starting at 0, -4 moves us 4 units to the left along our number line.
From there, another -2 moves us 2 more units to
the left along the number line and we end up at -6.
So -4 + -2 simplifies to -6.

Step-by-step explanation:
The formula for Fahrenheit temperature is
[tex]F=32+\dfrac{9}{5}C[/tex]
We need to write this formula for C.
Subtract 32 from both sides.
[tex]F-32=\dfrac{9}{5}C[/tex]
Multiply both sides by 5.
[tex]5(F-32)=9C[/tex]
Divide both sides by 9.
[tex]\dfrac{5}{9}(F-32)=C[/tex]
Therefore, the required formula is [tex]C=\dfrac{5}{9}(F-32)[/tex].

A point's coordinates are changed from (–7, –2) to (7, –2). What impact does this have on the location of the point?
The location of the point remains the same.
It is reflected over the y-axis.
The location of the point is shifted to the left.
It is reflected over the x-axis.
Answers
Answer: The answer would be "It is reflected over the x-axis"
Step-by-step explanation: The location wouldn't remain the same because the 7 is now a positive #. The y-axis hasn't changed. It's still the same -2. The location of the point would move, but it wouldn't move the the left. It would move to the right, because the negative numbers on the x-axis are on the left hand side, while the positive numbers are on the right hand side
Answer:When you reflect a point across the x-axis, the x-coordinate remains the same, but the y-coordinate is transformed into its opposite (its sign is changed). If you forget the rules for reflections when graphing, simply fold your paper along the x-axis (the line of reflection) to see where the new figure will be located.

What is a function rule?The function rule is the relationship between the input or domain and the output or range. A relation is a function if and only if there exists one value in the range for every domain value.
A function is a relation from a set of inputs to a set of possible outputs where each input is related to exactly one output.
Given data ,
Let the function be represented as A
Now , the value of A is given from the table of values as
Let the x values of the function be x = { -2 , -1 , 0 , 1 , 2 }
Now , the y values of the function is y = { 4 , 1 , 0 , 1 , 4 }
So , the function is a quadratic rule of the form .
y = x²
On simplifying , we get
f ( x ) = x² be equation (1)
Therefore , the value of A is f ( x ) = x²
Hence , the function is f ( x ) = x²

well you can remove the zeroes and factor either the 28 or 24. (I think 24 is the best) so when you factor it you get 2 and 12 because 2 x 12 is 24 and 2 + 2 + 12 + 12 is 28. Then add the zeroes and you have your dimensions. I hope that explanation helped with number 2.

Answer:
x = 34°
Step-by-step explanation:
To solve for 'x', we will need to use the Supplementary Angles theorem. This states that on a line, all angles must add up to 180°.
We can set up a simple algebraic equation to solve for 'x':
180 = x + 12 + 100 + x
180 = 112 + 2x **Combine like terms
68 = 2x **Divide both sides by '2'
x = 34°.
Therefore, the measure of ∠x = 34°.
Answer: x= 34
Step-by-step explanation:
x + 12 + 100 +x = 180 use the equation and combine like terms
2x + 112 = 180 subtract 112 from both sides
-112 -112
2x = 68 Divide both sides by 2
x = 34
Check: 34 + 12 +100 + 34 = 180
180 = 180

The midpoint of \overline{\text{AB}}AB is M(-2, 1)M(−2,1). If the coordinates of AA are (1, -2)(1,−2), what are the coordinates of BB?
Answers
Answer:
B=(-5, 4)
The coordinates of BB are (-5, 4)(-5,4)
Step-by-step explanation:
To solve, we will follow the steps below;
mid point = m(-2,1)
coordinates A is (1,-2)
To find the coordinates B
We will use the formula
([tex]x_{m}[/tex],[tex]y_{m}[/tex]) = ([tex]x_{1}[/tex] + [tex]x_{2}[/tex] /2 , [tex]y_{1}[/tex] +[tex]y_{2}[/tex]/2)
from the question
([tex]x_{m}[/tex],[tex]y_{m}[/tex]) = (-2,1)
this implies
[tex]x_{m}[/tex] = -2 [tex]y_{m}[/tex] = 1
Also
A([tex]x_{1}[/tex] , [tex]y_{1}[/tex]) B( [tex]x_{2}[/tex] ,[tex]y_{2}[/tex])
A(1, -2) B( [tex]x_{2}[/tex] ,[tex]y_{2}[/tex])
[tex]x_{1}[/tex]= 1 [tex]y_{1}[/tex] =-2
we are to look for [tex]x_{2}[/tex] and [tex]y_{2}[/tex]
[tex]x_{m}[/tex] = [tex]x_{1}[/tex] + [tex]x_{2}[/tex] /2
-2 = 1 + [tex]x_{2}[/tex] /2
multiply both-side by 2
-4 = 1+ [tex]x_{2}[/tex]
subtract 1 from both-side of the equation
-4-1 =[tex]x_{2}[/tex]
-5 = [tex]x_{2}[/tex]
[tex]x_{2}[/tex] = -5
Similarly,
[tex]y_{m}[/tex] = [tex]y_{1}[/tex] +[tex]y_{2}[/tex]/2
1 = -2+[tex]y_{2}[/tex]/2
multiply both-side of the equation by 2
2 = -2 +[tex]y_{2}[/tex]
add 2 to both-side of the equation
2+2 = -2+ 2 +[tex]y_{2}[/tex]
4=[tex]y_{2}[/tex]
[tex]y_{2}[/tex] = 4
