Answer:
3(3x-1)(3x+1)
Step-by-step explanation:
27x²-3
You can factor out a 3
3(9x²-1)
Now we can use the difference of perfect squares formula
x²-y²=(x+y)(x-y) which means that 9x²-1=
(3x-1)(3x+1)
put it all together and get
3(3x-1)(3x+1)
graph the image of M (–10,–7) after a rotation 180° counterclockwise around the origin.
Answer and Step-by-step explanation:
The point will be (7, 10).
#teamtrees #WAP (Water And Plant)
The image of the point M is M' = (10, 7) as shown in the graph below.
What is Coordinate Geometry?One of the most intriguing ideas in mathematics is called coordinate geometry. By using graphs with curves and lines, coordinate geometry (also known as the analytic geometry) explains how geometry and algebra are related.
As per the given data:
Coordinates of point M = (-10, -7)
Rotation to be given = 180° (counter - clockwise)
For drawing the image of point M (-10, -7):
Step 1: Create a line connecting the origin to the point M (-10, -7) and extending across the third and first quadrants.
Step 2: Modify the x and y coordinates signs to reflect the 180° rotation, then mark the point in the first quadrant.
The image of the point M is M' = (10, 7) as shown in the graph below.
Hence, the image of the point M is M' = (10, 7).

Which term has the definition "A fraction when the top and bottom cannot be any smaller, while still being whole numbers"? Group of answer choices Numerator Simplest Form Denominator Least Common Multiple (LCM)
Answer:
simplest form
Step-by-step explanation:
Simplest form is a method of converting the fraction to its lowest multiple.
For example, the fraction 25/100 isn't in its simplest form
Both the numerator and the denominator can be divided by 5. When divided by 5 the fraction becomes 5/20.
5/20 is still not in its simplest form because it can be divided by 5. When divided by 5, the fraction becomes 1/4.
1/4 is now in its simplest form because both the numerator and denominator cannot be divided by any other number

O 6 minutes
O 60 minutes
180 minutes
O 5,400 minutes
Answer:
A. 6 minutes
Step-by-step explanation:
6 minutes is 1/10 of an hour.
60 minutes is 1 hour.
5,400 minutes is 90 hours.
3 hours is 180 minutes. You can solve this as a proportion:
[tex]\frac{180}{30} =\frac{x}{1}[/tex]
Cross multiply to get 30x = 180. x = 6.

2. 1. Asia's new boat has a cruising speed of 27 miles per hour. At that rate, how long will it take her to travel the 3 miles across Old Hickory Lake?
Answer:Time = 1/9 Hours 0r 0.11111 hours
Step-by-step explanation:
We Know that Speed = Distance / Tim\e
Using the constant rate of the speed given as 27 miles per hour at
Distance = 3miles
Time = Distance / Speed
Time = 3 miles / 27miles per hour = 1/9 hours

Answer:
x+6 y+3
Step-by-step explanation:
The translation shows a horizontal shift to the left by 6 units and vertical shift up by 3 units
Reflection of coordinate pointsReflection of any coordinates are mirror images of each other.
The reflection rule of the coordinate over the x-axis is given as:
(x, y) -> (x , -y)
Using the coordinate (-1, 2) on the image on the left and (5, 1) for the coordinate on the right.
Reflecting (-1, 2) over the x-axis is (-1,-2). In order to determine the translation used from (-1, -2) to (5, 1)
(-1+x, -2+y) = (5, 1)
-1 + x = 5
x = 6
-2 + y = 1
y =3
The translation shows a horizontal shift to the left by 6 units and vertical shift up by 3 units
