Answer:

40 and 10

Step-by-step explanation:

Let the bigger number = x

Let the smaller number = y

x+y=50

x-y=30

(add the equations)

(x+x)+(y-y)=(50+30)

2x=80

x=40

x+y=50

40+y=50

y=10

stellarik [79]

Answer:

f(x) = (8/3)x(x - 1).

Step-by-step explanation:

The vertex form of the function is

y = a(x - 1/2)^2 - 2/3   where a is some constant.

Now the roots are 0 and 1 so

For  x = 0

0 =  a(-1/2)^2 - 2/3

1/4 a = 2/3

a = 2/3 / 1/4  = 8/3.

So the function is

f(x) = (8/3)(x - 1/2)^2 - 2/3.

3 f(x) = 8(x - 1/2)^2 - 2

= 8(x^2 - x + 1/4) - 2

=  8x^2 - 8x + 2 - 2

3 f(x) = 8x(x - 1)

f(x) = (8/3)x(x - 1).
