Name the line of reflection used to map each pre-image to its image.
Please help
Answer:
Step-by-step explanation:
From the picture attached,
9). When pre-image KLMN is a reflected across x = -2, we get image K'L'M'N'.
Therefore, line of reflection will be x = -2
10). In this picture line of reflection which passes through origin (0, 0) and slope = 1 will be,
y = x.
11). Since, all the points of image and preimage points are equidistant from x-axis, line of reflection will be x-axis or y = 0.
12). Line passing through midpoint of the line joining BB' will be the line of reflection.
Coordinates of B → (5, 3)
Coordinates of B' → (5, 7)
Coordinates of BB' → [tex](\frac{5+5}{2},\frac{3+7}{2})[/tex] → (5, 5)
Therefore, line of reflection will be y = 5.
13). Coordinates of G → (2, 5)
Coordinates of G' → (-2, 5)
Midpoint joining the segment GG' → [tex](\frac{2-2}{2},\frac{5+5}{2})[/tex] → (0, 5)
Therefore, line of reflection → x = 0
14). Line of reflection passing through (0, 0) and slope = -1
y = -x

Answer:
42
Step-by-step explanation:
3 is equal to 42 degrees because when you have two parallel lines that have another line pass through both parallel lines the values of degrees are the same as the opposite side so:
42 = 3
2 = 4
and another way you could find the value of 3 is since there is a perpendicular line going through line p we know that since it is perpendicular that the angle between them is 90 so angle 3 is:
90 - (angle 4) = angle 3
You may use this method if you first solved for angle 4 or angle 2 and we can get angle 2 from:
180 - 42 = 138
we can do this because 42 + angle two should be 180 degrees since they are along line n.

A triangle has side lengths of (1.2u+1.8v)(1.2u+1.8v) centimeters, (6.5u+8.7w)(6.5u+8.7w) centimeters, and (5.8w-6.9v)(5.8w−6.9v) centimeters. Which expression represents the perimeter, in centimeters, of the triangle? 13.5uw+3.6vw13.5uw+3.6vw 7.7u+1.8w+7.6v7.7u+1.8w+7.6v -1.1vw+15.2uw+3uv−1.1vw+15.2uw+3uv 14.5w-5.1v+7.7u14.5w−5.1v+7.7u
Answer:
7.7u - 5.1v + 14.5w
Step-by-step explanation:
Given length:
Side A = (1.2u+1.8v) centimeters,
Side B = (6.5u+8.7w) centimeters
Side C = (5.8w-6.9v) centimeters
Perimeter of a triangle = side A + side B + side C
= (1.2u+1.8v) + (6.5u+8.7w) + (5.8w-6.9v)
= 1.2u + 1.8v + 6.5u + 8.7w + 5.8w - 6.9v
Collect like terms
= 1.2u + 6.5u + 1.8v - 6.9v + 8.7w + 5.8w
= 7.7u - 5.1v + 14.5w
Therefore, the perimeter of the triangle is 7.7u - 5.1v + 14.5w
A taxi service charges you $1.50 plus $0.60 per minute for a trip to the airport. The distance to the airport is 10 miles, and the total charge is $13.50
How many minutes did the ride to the airport take?
Answer:
20 minutes
Step-by-step explanation:
The question can be shown like so, 1.5+0.6x
Since the total charge was 13.5, you can write an equation
13.5=1.5+0.6x
Simplify using property of subtraction
13.5 - 1.5= 1.5 - 1.5 + 0.6x
12 = 0.6x
Simplify using property of division
12/0.6= 0.6x/0.6

x - у - 2z = -6
3х + 2y = -25
—4х + у — z = 12
Answer:
(1) x-y-2z=-6 , (2) 3x+2y=-25 , (3) -4x+y-z=12
Step-by-step explanation:
Multiply (3) by 2,
-8x + 2y - 2z = 24
subtract above equation from (1)
9x - 3y = -30 --> 3x - y = - 10
subtract above equation from (2)
3y = -15 --> y = -5
Put y value back into (2)
3x + 2(-5) = -25 --> 3x - 10 = -25 --> 3x = -15 --> x = -5
Put x and y values into (3)
-4(-5) + (-5) - z = 12 --> 20 - 5 - z = 12 --> 15 - z = 12 --> z = 3
Hope its right good luck!!

Three times a number increased by 7 is 100. Find the number.
Answer:
31
Step-by-step explanation:
100-7= 93
93÷3=31
Answer:
the number is 31
Step-by-step explanation:
the number is the variable x
3 times the number is 3x
increased by 7 is +7
is 100 is =100
3x +7 =100
subtract 7 from both sides
3x =93
divide by 3 on both sides
x = 31
Given the definitions of f(x) and g(x) below, find the value of g(f(-3)).
Answer:
-11
Step-by-step explanation:
f(x) = 5x + 11
g(x) = x^2 + 4x - 11
g(f(-3)) = ?
f(-3) = 5(-3) + 11
= -15 + 11 = -4
g(f(-3)) = g(-4) = -(4)^2 + 4(-4) - 11
= 16 - 16 - 11 = -11
A function assigns the value of each element of one set to the other specific element of another set. The value of g(f(-3)) is -11.
What is a Function?A function assigns the value of each element of one set to the other specific element of another set.
Given f(x)=5x+11 and g(x)=x²+4x-11, therefore, we can write the value of g(f(x)) as,
g(f(x)) = (5x + 11)² + 4(5x + 11) - 11
= 25x² + 121 + 110x + 20x + 44 - 11
= 25x² + 130x + 154
Now, substitute the value of x as -3 in the function g(f(x)), therefore, we can write,
g(f(-3)) = 25x² + 130x + 154
= 25(3)² + 130(-3) + 154
= 225 - 390 + 154
= -11
Hence, the value of g(f(-3)) is -11.

9514 1404 393
Answer:
see below
Step-by-step explanation:
When a figure is rotated about a center point, the central angle formed by any point on the figure and the corresponding image point will be the rotation angle. Every image point is the same distance from the center of rotation that the pre-image point was. No lengths or angles are changed: rotation is a "rigid motion", so the rotated figure is congruent with the original.

-Angle AQA' is 60 degrees.
-Triangles ABC and A'B'C' are congruent.
-Angle ABC is congruent to angle A'B'C'. (this is one of the angles of the congruent triangles)
-Segment BC is congruent to segment B'C'
-Segment AQ is congruent to segment A'Q.
