Reflections

1) Reflecting over y=x means (x, y) \longrightarrow (y,x). So, the coordinates of the image are:

V(-3, 0) \longrightarrow V'(0,-3)\\\\W(-1,0) \longrightarrow W'(0, -1)\\\\U(-2,-5) \longrightarrow U'(-5,-2)\\\\X(3,-3) \longrightarrow X'(-3, 3)


2) Rotating 90 degrees counterclockwise about the origin means (x,y) \longrightarrow (-y,x), so the vertices of the image are:

W(0,-1) \longrightarrow W'(1,0)\\\\X(3,-1) \longrightarrow X'(1, 3)\\\\V(0,-3) \longrightarrow V'(3,0)\\\\Y(1, -5) \longrightarrow Y'(5, 1)

3) The vertices of the image are:

C(2,0) \longrightarrow C'(-2, -2)\\\\D(2, 5) \longrightarrow D'(-2, 3)\\\\E(5,4) \longrightarrow E'(1, 2)

now you can divide 16 and 100 by 4 which would be

16/4 = 4 and 100/4= 25

Help pls, i'm stuck on this question
dalvyx [7]

Answer:

∠x = 60°

Step-by-step explanation:

first:

∠a = 60° was given

the sides on each side of ∠a are equal so their opposite angles are equal also.

The sum of the interior angles of any triangle is 180°

The angles opposite ∠a are (180° - 60°)/2 = 60° each

Second:

∠b = 60° was given

so the angles opposite ∠b are also 60° each

Third:

the 2 angles opposite x are both 60° each because they are both vertical angles to 60°

That leaves ∠x  to be 180° - 60° - 60° = 60°

zubka84 [21]

Answer:

a) L = 4p

b ) 24 light bulbs

Step-by-step explanation:

Robin is buying energy-efficient light bulbs. Each package of 4 light bulbs costs $13. She has a coupon for $5 off her total purchase.

Each package of 4 light bulbs costs $13.

a.Write an equation to determine the total number of light bulbs, L, for p packages.

1 package = 4 bulbs

L = 4p

Where p = number of packages

b) Then determine the number of light bulbs Robin will get if she buys 6 packages. Show your work.

L = 4p

p = 6 packages

L = 4 × 6

L = 24 light bulbs

iVinArrow [24]

Answer:

No of total brown = 2 + 1 = 3 .

probability = 3 / 6

= 1 /2 .

no of males = 2

probability

= 2 / 6

= 1 /3

no of person who is both male and brown = 1

probability = 1 /6

Required probability

= probability of being brown + probability of being male - probability of being both

= 1 / 2 + 1 / 3 - 1 /6

= 4 / 6

= 2 / 3 .
