Answer:

94

Step-by-step explanation:

Given f(g(-5)) means that you take the number, -5, and substitute it into g(x) first. The answer provided from that equation will then be the number to be substituted in f(x).

x^2 + 4

-5^2 + 4

25 + 4 [It's positive because -5 x -5 cancels out to make a positive]

29 = g(x), therefore, this is the new number to be substituted for f(x)

3x + 7

3 (29) + 7

87 + 7 [to get 87, multiply 3 by 29]

94

Therefore, your final answer is 94.

Hope this helps!

Evaluate f(x)= -6+12 when x= -3,x=0, and x=1.
Anton [14]

Given :

A function, f(x) = -6 + 12

To Find :

The value of f(x) when x= -3, x= 0 and x=1.

Solution :

Given function is f(x) = -6 + 12 .

Simplifying above function, we get :

f(x) = 6

Now, the given function is independent of x.

So, for any value of x the the value of functions remains constant.

Hence, this is the required solution.

Using the porpotions: WHIP= (Walks+Hits) divide by Innings Pitched. The pitcher wants to lower his WHIP from 1.53 to 1.3. How ma
BaLLatris [955]
This relates to ur previous question....there were 85 innings last question and 130 walks + hits which gave a whip score of 1.53......so if he wants to lower his whip (without changing his walks or hits) to 1.3....
130 / (85 + x) = 1.3....multiply both sides by (85 + x)
130 = 1.3(85 + x)
130 = 110.50 + 1.3x
130 - 110.50 = 1.3x
19.5 = 1.3x
19.5 / 1.3 = x
15 = x

he would have to pitch 15 more innings without any walks or hits to reach a goal of 1.3 whip score. This is not a reasonable goal.....have u ever seen a baseball game where a pitcher pitched 15 innings without any walks or hits ? And since a game consists of 9 innings....he would be 3 innings short of 2 games (thats if they dont go into overtime), and he would have to pitch a no hitter....and that is highly unlikely.
