That is point slope form

y-y1=m(x-x1)

passes through the point (x1,y1) and has a slope that is m

The function f(x) varies inversely with x and f(x)=8 when x=3

Sedaia [141]

Answer:

$12$

Step-by-step explanation:

we know that

A relationship between two variables, x, and y, represent an inverse variation if it can be expressed in the form $y*x=k$ or $y=k/x$

In this problem we have

For $x=3$ -----> $f(x)=8$

Find the value of k

$f(x)*x=k$

substitute the value of x and f(x)

$8*3=k$

$k=24$

therefore

the equation is equal to

$f(x)=24/x$

For $x=2$ -------> substitute in the equation and find the value of f(x)

$f(x)=24/2=12$

Solve x^2 - 4 = 77.

Gennadij [26K]

Answer:

X = 9 or x = -9

Step-by-step explanation:

We want to solve the quadratic equation

${x}^{2} - 4 = 77$

We shall use the square root method

Let us add 4 to both sides to get:

${x}^{2} - 4 + 4 = 77 + 4$

${x}^{2} = 81$

We take square to get:

$x = \pm \sqrt{81}$

$x = \pm9$

The solution is x=9 or -9
