When you multiply any whole number by the one before it, the result is always an even number.

1 answer:

8 0

Verrrrrrry interesting ! / / / Every multiple of an even number is another even number. When you take any whole number and the one 'before' it ... no matter which direction 'before' means .... one of the numbers is even. So their product is a multiple of an even number, and it must be another even number.

Which is it? , 30 points

goldenfox [79]

Answer:

It's choice B.

Step-by-step explanation:

Let's look the one you have chosen (A):

f(x) = x - 2/ 7 + 8

x-2 / 7 = f(x) - 8

x- 2 = 7(f(x) - 8)

x = 7(f(x) - 8) + 2

The inverse)= 7(x - 8) + 2

So it's not A.

B. f(x) = 5(x/4) - 3

5x / 4 = f(x) + 3

5x = 4(f(x) + 3)

x = 4(f(x) + 3 / 5

So the inverse is 4(x + 3) / 5

So it is B.

If f(x) = x/2 - 3 an g(x) = 3x^2 + x-6, find (f+g)(x)

PilotLPTM [1.2K]

Answer:

(f + g)(x) = 3x^2 + 3x/2 - 9

Step-by-step explanation:

In order to find a composite function through addition, you simply add the two equations together.

f(x) + g(x)

x/2 - 3 + 3x^2 + x - 6

3x^2 + 3x/2 - 9
