The difference between 2 numbers is 8. The sum of the two numbers is 20. Find the number. ​
Igoryamba

Answer:

The numbers are 6 and 14

Step-by-step explanation:

Let the two numbers be x and y

x-y = 8

x+y = 20

Add the two equations

x-y = 8

x+y = 20

-----------------

2x = 28

Divide by 2

2x/2 = 28/2

x = 14

Subtract the two equations

x-y = 8

-x-y = -20

-----------------

-2y = -12

Divide by -2

-2y/-2 = -12/-2

y = 6

The numbers are 6 and 14

If f(x) = x^2 - 2x and g(x) = 6x + 4, for what value of x does (f + g)(x) = 0?
larisa86 [58]

Answer:

x = -2

Step-by-step explanation:

f(x) =x^2 -2x\:\: and \:\: g(x) = 6x + 4\\(f+g)(x) = f(x) + g(x) \\(f+g)(x) = x^2 -2x+ 6x + 4\\(f+g)(x) = x^2+4x + 4\\(f+g)(x) = (x+2)^2\\ 0 = (x+2)^2...[\because (f+g)(x) =0]\\0 = x+2\\\therefore x = -2
