Answer:

Step-by-step explanation:

for this function you have to replace the function of g(x) where there's x in the function f(x) that's what the expression f.g(x) means and so this is going to be

3(x²+1)+2

I hope this helps

A positive number is multiplied by itself and then 7 is added. The answer is 16. What is the number?

Alika [10]

Answer:

Step-by-step explanation:

let the number be n then multiplied by itself gives n², thus

n² + 7 = 16 ( subtract 7 from both sides )

n² = 9 ( take the square root of both sides )

n = $\sqrt{9}$ = 3

The graph of x = 2(y-4) and x = 5(y-4) are shown below answer my following question to receive brainlest!!!

Ivanshal [37]

Answer:

The graph $x = 2(y - 4)$ has a greater slope than the graph of $x = 5(y - 4)$ .

Step-by-step explanation:

$x = 2(y - 4)\\\frac{x}{-2y} = \frac{-2y}{-2y} - 4\\-2y \frac{x}{-x} = \frac{-4}{-x} \\\frac{-2y}{-2} = \frac{-1x}{-2} \frac{-4}{-2}\\y = \frac{1}{2}x + 8$ $x = 5(y - 4)\\\frac{x}{-5y} = \frac{5y}{-5y} - 20\\\frac{x}{-x} - 5y = \frac{-20}{-x}\\\frac{-5y}{-5} = \frac{-1x}{-5} \frac{-20}{-5}\\y = \frac{1}{5}x + 4$
