Images of transformation are congruent if they were translated, mirrored/flipped or rotated

1)
(x, y) → (–x, –y) mirrored
(x, y) → (0.8x, 0.8y) scale->not congruent
(x, y) → (x, y + 5)

2)
(x, y) → (x, –y) mirrored
(x, y) → (–x, y) mirrored
(x, y) → (x + 1, y – 1) translation
-> is congruent

3)
(x, y) → (x + 5, y + 5) translation
(x, y) → (x, –y) mirror
(x, y) → (2x, y) scale-> not congruent

4)
(x, y) → (3x, 3y) scale->not congruent
(x, y) → (–x, y)
(x, y) → (x – 4, y)

so the second series of transformations is the only one with a congruent after image

-5+ 3= 2) -7 -4 3) 122 × (-9) 4) -6 divided by 3/4
lutik1710 [3]

Answer:

Step-by-step explanation:

1) -5 +3 = -2

When two numbers are in different sign, subtract and the result will have the bigger numbers sign.  The bigger number is 5. so the result is (-2)

2) -7 - 2 = -9

When two numbers have same sign, add and the result will have the common sign

3) 122 * (-9) = - 1098

4) -6 ÷ (3/4)

=(-6)*\frac{4}{3}\\\\=-2*4

= -8

Arturiano [62]

Answer:

153 ways.

Step-by-step explanation:

The answer is the number of combinations of 2 from 18

= 18! / 2! (18-2)!

= 18! / 2! 16!

= 18*17*16! / 2! 16!

= 18 * 17 / 2*1

= 9 * 17

= 153 ways.

If Jace had 77 blue pens,23 red pens 15 pink pens and 4 purple pens what is the part to whole ratio for red pens to all of the p
Pie

Answer:

23:119

Step-by-step explanation:

all pens:

77 blue + 23 red + 15 pink + 4 purple

77 + 23 + 15 + 4 = 119

119 total pens

23 red / 119 total

23/119

23 is prime, so this cannot be simplified further

the ratio of red : total pens is 23:119
