Describe the transformation of the graph y = (x + 3)2 – 4 from the parent function y = x².
a. left 3 and down 4
b. right 3 and down 4
c. left 4 and up 3
d. right 4 up 3

it would rotate about 180 degrees.

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)

the answer is b.

64

step-by-step explanation:

c=2πr=2·π·8≈64

you need to rotate this triangle about the origin 270 degrees clockwise to create the full square.
