Please help ASAP. I'm so confused.

f(x) = x² - x - 6

That's part 1.

2. Factor

x² - x - 6 = (x - 3)(x + 2)

(x - 3)(x + 2)

3. Find zeros

(x - 3)(x + 2) = 0

x = 3 or x = -2

4. There is no context and nothing ever makes "since."  Amateurs.

I'll guess this came from a geometry problem or something where x has to be positive.

x=3 makes sense

5. Explain each item and show work.

Not sure what they're talking about here; hopefully that's what we've done up till now.

f is the midpoint of

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)
