Please help I am broke now D: Given a triangle with vertices A(4, -1), B(-3,0), and C(7,2), which points represent a reflection of Triangle ABC in the y-axis?
O A(4,1), B(-3,0) (7,-2)
O None of the other answers are correct
O A(-4,-1), B(3,0), C(-7,2)
O A(-1,4), B(0, -3). C(2,7)
O A(-4,1), B(3,0), C(-7, - 2)

Step-by-step explanation:

(C).  A( - 4, - 1 ), B( 3, 0 ), C( - 7, 2 )

i can answer this question sweetie!

step-by-step explanation:

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)
