If you want to simplify the expression, combine like terms

x and 3x go together, so they make 4x.

and 4 is just 4

So, the answer is

4x + 4

Answer:16/15

Step-by-step explanation:

slope= $\frac{y_{2}- y_{1} }{x_{2}-x_{1} }$

= $\frac{-14-18}{-11-19}$

= $\frac{-32}{-30}$

= $\frac{16}{15}$

The sum of two numbers is ten. The difference of the two numbers is 14. Find the<br> two numbers.

Mashcka [7]

Answer:

Step-by-step explanation:o

x + y = 10........(1)

x - y = 14..........(2)

Adding (1) and (2)

2x = 24

x = 24/2

x = 12

And x + y = 10.......(1)

12 + y = 10

y = 10 - 12

y = -2

The number are 12 and -2

Identify the relative maximum value of g(x) for the function shown below <br><br> g(x) = 2/ x^2 +3

Dahasolnce [82]

Answer:

The relative maximum value is $\frac{2}{3}$

Step-by-step explanation:

The given function is

$g(x)=\frac{2}{x^2+3}$

We differentiate to obtain;

$g'(x)=-\frac{4x}{(x^2+3)^2}$

At turning points $g'(x)=-\frac{4x}{(x^2+3)^2}=0$

$\implies x=0$

$g''(x)=\frac{16x^2}{(x^2+3)^3}- \frac{4}{(x^2+3)^2}$

We apply the second derivative test to obtain:

$g''(0)=\frac{16(0)^2}{((0)^2+3)^3}- \frac{4}{((0)^2+3)^2}=-\frac{4}{9}$

Since the second derivative is negative, there is a relative maximum at x=0.

We substitute x=0 into the original function to obtain the relative maximum value.

$g(0)=\frac{2}{(0)^2+3}=\frac{2}{3}$
