Name the line of reflection used to map each preimage to its image
rewona [7]

Answer:

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' →  → (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' →  → (0, 5)

    Therefore, line of reflection → x = 0

14). Line of reflection passing through (0, 0) and slope = -1

    y = -x

Equilateral triangle ABC has a perimeter of 96 millimeters. A perpendicular bisector is drawn from angle A to side BC at point M
a_sh-v [17]

Answer:

16 mm  

Step-by-step explanation:

Since ABC is an equilateral triangle, all three sides are the same length.  The perimeter is found by adding together all of these equal sides; letting x represent the length of a side of the triangle, this gives us

x + x + x = 96

Combining like terms,

3x = 96

Dividing both sides by 3,

3x/3 = 96/3

x = 32

Since AM is a perpendicular bisector, it splits BC into two congruent sections. This means the length of MC, half of BC, will be 32/2 = 16.

Solve <br><br> 2(x/4 + 8) = 18
PIT_PIT [208]

Answer:

x = 4

Step-by-step explanation:

2(x/4 + 8) = 18

First: Distribute 2 into "x/4 + 8".

2x/4 + 16 = 18

2x/4 = 18 - 16

1x/2 = 2

x/2 • 2 = 2 • 2

x = 4

P.S "•" means to multiply.

Hope This Helps! •v•

What remainder does the number (−50) leave after division by 7?
m_a_m_a [10]
This is a tricky question, all you need to know is that the remainder cannot be a negative number.

So, -50 mod 7 = 6, since -50 /7 = 8 with remainder of 6
