Answer:

x = - 4

Step-by-step explanation:

The slope is the ratio of rise to run.

Rise is the difference of y-coordinates, run is the difference of x-coordinates.

Now, the slope is said undefined if the difference of x-coordinates is zero.

It means you have to divide by zero but it is impossible.

We have a point (- 4, - 8) and the slope is undefined.

It means our line has repeat x = -4 coordinates, it is a vertical line.

<u>Its equation will be:</u>

x = - 4

Let's write the equation

m=undefined
Point (-4,-8)

$\\ \sf\longmapsto y=mx+b$

Line is parallel to y axis

$\\ \sf\longmapsto x+4=\dfrac{-8}{\infty}$

$\\ \sf\longmapsto x+4=0$

$\\ \sf\longmapsto x=-4$

A carton of paper is priced at 27.00 now if the paper goes on sale for 25% off the current price what will be the sale price of

hjlf

Okay, to solve this we simply find 75% of the carton of paper, because 100%-25% = 75%

0.75(27) = 20.25

The carton of paper costs $20.25

If f(x) and g(x) are polynomial functions, what is the domain of f(x) + g(x) ?

IRINA_888 [86]

Answer:

all real numbers or $(-\infty, \infty)$

Step-by-step explanation:

since both f(x) and g(x) are polynomials, neither of them have restrictions on their domains. Since they can be defined for all real numbers. It's not like the square root which has a domain of (0, infinity), or log x which is defined only from (0, infinity). So adding these two polynomials would result in a domain of all real numbers.
