Solve the question for y
2x+8y=16

2x     +    8y     =     16

Let's solve for y.

2x     +   8y    =     16

Step 1: Add  -2x   to both sides.

2x    +   8y     +   −2x    =     16    +       −2x

8y     =      −2x        +          16

Step 2: Divide both sides by 8.

8y / 8       =         -2x    +    16 / 8

y        =            -1 / 4x   +   2

Answer    ==============>      y            =           -1 / 4x   +   2

Graph:      

2x        +     8y       =    16

y       =      -1 / 4x    +   2

Hope that helps                                        : )

think the answer would beb

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)
