Find the glide reflection rule to map ΔABC onto ΔA′B′C′ in the given figure. Question 9 options:
A)

Translation: (x, y) → (x, y + 7); Reflection across the x-axis

B)

Translation: (x, y) → (x + 7, y); Reflection across the x-axis

C)

Translation: (x, y) → (x + 7, y); Reflection across the y-axis

D)

Translation: (x, y) → (x – 7, y); Reflection across the x-axis

the answer would be 1 1/72

step-by-step explanation:

you can rewrite the equation by separating the parts and then solving individually:

10-9=1

1/8 - 1/9=

find l c d and then combine:

1 1/72

sorry i just need to anwers this to get points

step-by-step explanation:

$450 i think. hope this ☺

delaney would like to make a 5lb nut mixture that is 60% peanuts and 40% almonds.

she has several pounds of peanuts and several pounds of a mixture that is 20% peanuts and 80% almonds.

let 'p' represent the number of pounds of peanuts needed to make the new mixture, and  

let 'm' represent the number of pounds of the 80% almond-20% peanut mixture.

:

p + m = 5

therefore

m = (5-p)

write an equation based on the percent of peanuts

1p + .2m = .6(5)

replace m with (5-p)

p + .2(5-p) = .6(5)

p + 1 - .2p = 3

p - .2p = 3 - 1

.8p = 2

p = 2/.8

p = 2.5 lbs of peanuts required

then

5 - 2.5 = 2.5 lbs of the peanut/almond mixture required

:

a) what is the system that models this situation?

p + m = 5

1p + .2m = .6(5)
