Answer:

The most reasonable is 2 h

Step-by-step explanation:

If you see the graph is decreasing in hours while is increasing in years. When a person is 45 years the amount of daily physical activity is 3 hours, so a person that is 50 years needs to do less than 3 hours a day and the only option less than 3 hours is 2 hours.

If f(x)=x2-2x and g(x) =6x+4, for whichvalue of x dose (f+g)(x)=0
Juliette [100K]

Answer:

The value of x that makes the equation equal to 0 is -2.

Step-by-step explanation:

In order to find this, we first must create the composite function using the designated operation. The operation is addition, so we just add them together.

f(x) + g(x) = (f+g)(x)

(x^2 - 2x) + (6x + 4) = (f+g)(x)

x^2 + 4x + 4 = (f+g)(x)

Now, in order to find when this is equal to 0, we need to factor.

x^2 + 4x + 4 = 0

(x + 2)(x + 2) = 0

When it is fully factored, we can set each parenthesis equal to 0 in order to find the value. Since the parenthesis are exactly the same, we only have to do this once.

x + 2 = 0

x = -2
