Answer:

x=0,4.

Step-by-step explanation:

We have been given two functions.f(x) = x^2-2x-4 and g(x) = 2x - 4. We are asked to find the point, where both functions intersect.

To find the intersection point of both graphs, we will equate both equations as:

x^2-2x-4=2x-4

Combine like terms:

x^2-2x-2x-4+4=2x-2x-4+4

x^2-4x=0

Now, we will factor out x as:

x(x-4)=0

Using zero product property, we will get:

x=0\text{ (or) }x-4=0

x=0\text{ (or) }x=4

Therefore, the both graphs intersect at x=0,4.

x = 0 and x = 4

To find intersection equate them.

x² - 2x - 4 = 2x - 4

subtract 2x - 4 from both sides

x² - 4x = 0 → (take out common factor x)

x(x - 4 ) = 0 ⇒ x = 0 , x = 4

The sum of two numbers is equal to 63, and their difference is equal to 12. Find the numbers ​
Ainat [17]

Answer:

25.5   and   37.5

Step-by-step explanation:

x+y=63

x-y = 12    then   x = 12 + y      sub this into the first equation

(12+y)    + y = 63

12 + 2y = 63

2y = 51

y = 25.5     then x = 37.5
