Review the graph of a parabola. On a coordinate plane, a parabola opens to the right. It goes through (3, 0), has a vertex at (negative 2, negative 3), and goes through (0, negative 5).

Which equation represents the curve shown?

2(x + 2) = (y + 3)2
2(y + 2) = (x + 3)2
–2(y + 2) = (x + 3)2
–2(x + 2) = (y + 3)2

step-by-step explanation:

answer: 40392

step-by-step explanation:

10098 x 4 = 40392

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)

this is a good question! i’ll do some research and what i find, i’ll contact you asap when i have something! ✊
