What are the coordinate of triangle ABC when reflected over the line y = -x? A(1, 2), B(-2, 0), C(1,-4)
A (2, 1), B'(0, 2), C'(4,1)
O A' (2,-1), B'(0, -2), C'(4, -1).
O A'(1,2), B'(0, 2), C'(4,1)
O A'(-2, -1), B'(0, 2), C'(4,-1)

the answer is 54 sq. ft. i just did this question, on odyssey ware, and it was right. make brainliest.

it should be a.

hope it

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)
