F as a function of x is equal to the square root of quantity 6 x plus 9 , f as a function of x is equal to the square root of qu

Elis [28]

Answer:

A. $\sqrt{6x+9} +\sqrt{6x-9}$

Step-by-step explanation:

We are given the functions f(x) and g(x) as,

$f(x)=\sqrt{6x+9}$

$g(x)=\sqrt{6x-9}$

It is required to find the function ( f+g ) i.e. ( f+g ) (x)

So, $(f+g)(x)=f(x)+g(x)$

i.e. $(f+g)(x)=\sqrt{6x+9}+\sqrt{6x-9}$

Hence, we get that $(f+g)(x)=\sqrt{6x+9}+\sqrt{6x-9}$ .

So, the first option is correct.

What line has slope of 5/8 and goes through the point (2,-3)

sweet-ann [11.9K]

Slope of a line passing through a point is given by: y - y1 = m(x - x1); where (x1, y1) = (2, -3) and m = 5/8.
Therefore equation of the line is y - (-3) = 5/8(x - 2)
8(y + 3) = 5x - 10
8y + 24 = 5x - 10
8y - 5x = -10 - 24 = -34
5x - 8y = 34

Circle O has a circumference of 88π cm.

Lena [83]

Answer

Step-by-step explanation:

R = C/(2*Pi).

So, in order to find the radius from the circumference, you use the formula R = C/(2*Pi). In other words, just divide the circumference by 2 times pi.
