Suppose that f(x) = x + 4 and g(x) = -x + 3. Find (f )(g)(4).
stellarik [79]

Answer:

-12

Step-by-step explanation:

I am assuming that you want (f*g)(4), which is the product of f and g at x = 4.

If this is actually the case, then one way to evaluate (f*g)(4) is to find f(4) and g(4) separately and then multiply the results together.  This gives us

f(4)*g(4) = (8 + 4)*(-4 + 3) = -12

Three times the second of three consecutive even integers is twelve less than twice the sum of the first and third integers.Find
Tresset [83]

Answer:

The largest even integer is <u>14</u>.

Step-by-step explanation:

Given:

Three times the second of three consecutive even integers is twelve less than twice the sum of the first and third integers.

Now, to find the largest even integers.

As, 2 is an even number.

Let an even integer be 2x.

So, the three consecutive even integers are:

2x,\ 2x+2,\ and\ 2x+4.

Now, we have to add two to get next even number.

Thus, 3 times the second one of these is:

3(2x + 2) \\= 6x + 6

Now, the sum of the first and third ones are:

2x + 2x + 4 \\= 4x + 4

So, the twice the sum of the first and third integers is less than twelve:

2(4x+4)-12\\=8x+8-12\\=8x-4

Now, 3 times the second is 12 less than twice the sum of the other two:

6x+6=8x-4

<em>Getting the variables on one side and the number on other:</em>

6+4=8x-6x

10=2x

<em>Dividing both sides by 2 we get:</em>

5=x

x=5.

Now, the even numbers we get are:

2x=2\times 5=10\\2x+2=2\times 5+2=10+2=12\\2x+4=2\times 5+4=10+4=14.

<em>Thus, the third number is the largest number which is 14.</em>

Therefore, the largest even integer is 14.
