Value of this problem?

Rudik [331]

$\frac{4^3\times4^{-1}\times5^{-2}}{4^4\times5^{-3}\times5^0}=\frac{4^{3-1}\times5^{-2}}{4^4\times5^{-3+0}}\\=\frac{4^{2}\times5^{-2}}{4^4\times5^{-3}}=4^{2-4}\times5^{-2-(-3)}\\=4^{-2}\times5^{1}=\frac{5}{4^2}\\=\frac{5}{16}$

What ate the domain and range of f(x)(1/6)x+2?

never [62]

Answer:

Domain : all real numbers

Range: All numbers greater than 2

Step-by-step explanation:

The shark. (Haha, I'm sorry.)

There are no restrictions on the x. X can be any real number.

The range, however, does have restrictions. The range has to be a number greater than 0.

Why?

Because any number that you put in for x won't make the range less than 2. If you put in zero for x, the range is 2.

How to find equation of line passing through the points (x,y)

DochEvi [55]

First you must acknowledge that you are dealing with a line therefore you must write linear equation or linear function in this case.

Linear function has a form of,

$y=mx+n$

Then calculate the slope m using the coordinates of two points. Let say A(x1, y1) and B(x2, y2),

$m=\dfrac{\Delta{y}}{\Delta{x}}=\dfrac{y_2-y_1}{x_2-x_1}$

Now pick a point either A or B and insert coordinates of either one of them in the linear equation also insert the slope you just calculated, I will pick point A.

$y_1=mx_1+n$
