Here is trapezoid A in the coordinate plane:
If you drew Trapezoid C, the image of A after a reflection over the y-axis, what would be the coordinates of each of the vertices?
Answer:
(-2,1) (-2,3) (-4,1) (-4,4)
Step-by-step explanation:
Simply select each of the points, Count how many squares away that point is away from the line of reflection (the y-axis) and Put that point the same distance/amount of squares away on the other side of the y-axis. Join up the points and then you get your answer!

Answer:
y = 1500x + 20690
Step-by-step explanation:
We already know the slope. The prompt tells us that in 1996 there were 29,690 movie screens. We can write this as the point (6, 29690). We can find the y-intercept by substituting information into the point-slope formula.
[tex]y-y_1=m(x-x_1)\\\\y-29690=1500(x-6)\\\\y-29690=1500x-9000\\\\y=1500x+20690[/tex]
Now we know that number of movie screens in 1990 was 20,690 and that it increased by 1500 each year.

On the graph, △DEF was transformed to create △DGH.
Which transformations show that △DEF is similar to △DGH?
A
a dilation by a scale factor of 6 and then a 180° rotation about the origin
B
a dilation by a scale factor of 6 and then a translation 6 units down and 6 units left
C
a dilation by a scale factor of 3 and then a 180° rotation about the origin
D
a dilation by a scale factor of 3 and then a translation 6 units down and 6 units left
Answer:
it's B
Step-by-step explanation:
by analyzing it I figured it was 100% B
Answer:
C. a dilation by a scale factor of 3 and then a 180 degrees rotation about the origin.
Step-by-step explanation:
G is the same point transformed as E and H is the same as point F.
Since G is now (-9,0) that was multiplied 3 times from (3,0) before it was rotated. Which would show that the answer is probably C or D.
Next, the answer looks as though it has been rotated around D or the origin by 180 degrees but we don't know that quite yet.
So check if you dilated triangle DEF by a factor of 3 then translated it down 6 units point E would now be (9,-6).
Then translate it to the left 6 units. (3, -6). That's not the same as triangle DGH.
So the answer is C.
Hope this helps! If it does brainliest would be appreciated.

Perform the indicated operation. Simplify the result in factored form.
Answer:
[tex]\frac{a+1}{(a-2)(a-1)(a-1)}=[/tex]
Step-by-step explanation:
1. Approach
The easiest method to solve this problem is to factor the expression. In order to subtract (or add) two fractions, both fractions have to have common denominators. When the fractions are factored one can easily see the least common denominator. Convert both fractions to the least common denominator by multiplying the numerator (number over the fraction bar) and denominator (number under the fraction bar) by the value such that both fractions have the same denominator. Finally, one can subtract the numerators of the two fractions.
2. Factoring and Least common denominator
[tex]\frac{3}{a^2-3a+2}-\frac{2}{a^2-1}=[/tex]
Factor the expression, rewrite the quadratic polynomials as the product of two linear polynomials,
[tex]\frac{3}{a^2-3a+2}-\frac{2}{a^2-1}=[/tex]
[tex]\frac{3}{(a-2)(a-1)}-\frac{2}{(a-1)(a+1)}=[/tex]
The least common denominator is: ([tex](a-2)(a-1)(a-1)[/tex])
Convert both fractions to the least common denominator, multiply both the numerator and denominator by the same value to do so,
[tex]\frac{3}{(a-2)(a-1)}-\frac{2}{(a-1)(a+1)}=[/tex]
[tex]\frac{3}{(a-2)(a-1)}*\frac{a-1}{a-1}-\frac{2}{(a-1)(a+1)}*\frac{a-2}{a-2}=[/tex]
Simplify,
[tex]\frac{3}{(a-2)(a-1)}*\frac{a-1}{a-1}-\frac{2}{(a-1)(a+1)}*\frac{a-2}{a-2}=[/tex]
[tex]\frac{3(a-1)}{(a-2)(a-1)(a-1)}-\frac{2(a-2)}{(a-1)(a+1)(a-2)}=[/tex]
3. Solving the expression
[tex]\frac{3(a-1)}{(a-2)(a-1)(a-1)}-\frac{2(a-2)}{(a-1)(a+1)(a-2)}=[/tex]
Distribute, multiply every term inside the parenthesis by the term outside of it,
[tex]\frac{3(a-1)}{(a-2)(a-1)(a-1)}-\frac{2(a-2)}{(a-1)(a+1)(a-2)}=[/tex]
[tex]\frac{3a-3}{(a-2)(a-1)(a-1)}-\frac{2a-4}{(a-1)(a+1)(a-2)}=[/tex]
Simplify further,
[tex]\frac{3a-3}{(a-2)(a-1)(a-1)}-\frac{2a-4}{(a-1)(a+1)(a-2)}=[/tex]
[tex]\frac{3a-3-(2a-4)}{(a-2)(a-1)(a-1)}=[/tex]
[tex]\frac{3a-3-2a+4}{(a-2)(a-1)(a-1)}=[/tex]
Combine like terms,
[tex]\frac{3a-3-2a+4}{(a-2)(a-1)(a-1)}=[/tex]
[tex]\frac{a+1}{(a-2)(a-1)(a-1)}=[/tex]

find three consecutive integers for which 3 times the sum of the first and third integers is -342? show step by step
Answer:
The integers are -58, -57, -56.
Step-by-step explanation:
The difference between two consecutive integers is 1.
If you let the smallest of the three consecutive integers equal x, then the next greater one is x + 1, and the greatest of the three is x + 2.
Integers: x, x + 1, x + 2
The sum of the first and third is: x + x + 2
3 times the sum of the first and third is: 3(x + x + 2)
That product equals -342.
3(x + x + 2) = -342
3(2x + 2) = -342
Divide both sides by 3.
2x + 2 = -114
Subtract 2 from both sides.
2x = -116
Divide both sides by 2.
x = -58
x + 1 = -57
x + 2 = -56
The integers are -58, -57, -56.

2a = 2-4
2a = -2
a = -1

Circle question of the rug
That you needed answer for is ;
3/4 pi^2
Step-by-step explanation:
Proof 1/4 pi r^2
We can state the radius of small rug is 3ft
to show Area pi 3^2 = pi 9
If the large rug is 3x this size
then pi 9^2 = pi81
So the ratio here is 1 : 9 when 3 cm or 1 : 3 radius
Ratio is 1 : 9 when 1cm or 1 : 3 radius
When 1 : 9 cm when 5cm or 1 : 3 radius
So if we are considering an expression of the larger rug
that shows 3: 1 more radius to that of the small.
1/4 pi^2 becomes 3/4 pi^2 of the smaller rug
As this is 3 x 1/4 pi^2 we show 3/4pi r^2

I WILL MARK BRAINLIEST! What is the surface area and the volume of this Cylinder?
Answer:
Surface Area = 264π
Volume = 576π
Step-by-step explanation:
in the picture
Answer:
SA= 829.38 Inches² which is 829.38/3.14159 = 264π inch³
V = 110.43 inches³. which is 110.43/ 3.14159 = 35.15π inch³
Step-by-step explanation:
To find the surface area of cylinder, we calculate two area of circle 2πr² and one area of rectangle 2πrh first, and then add them 2πr²+2πrh.
SA of a cylinder =2πrh+2πr², where π≈3.14159
Radius given is 12/2 = 6 inches
= 2 x π x 6 x 16 + 16 x π6 x 6 ≈ 829.3804 = 829.38 Inches²
Volume = h*π *r^2
V = 16 x π
= 110.43 inches³.
