A small publishing company is planning to publish a new book. The production costs will include one-time fixed costs (such as ed

Lady_Fox [76]

Answer:

for 3644 produced books the costs will be the same.

Step-by-step explanation:

x = number of books

f(x) = production method 1 costs

g(x) = production method 2 costs

f(x) = 11.75x + 57077

g(x) = 21.25x + 22459

for what number of books (x) will that be the same ?

11.75x + 57077 = 21.25x + 22459

34618 = 9.5x

x = 34618 / 9.5 = 3644

A line passes through (3, -2) and (6,2). Write an equation for the line in point-slope form.

snow_lady [41]

Answer:

4x - 3y -18 = 0 or y = 4x/3 - 6

Step-by-step explanation:

We will have to find the slope of the line first

The formula for slope:

$m =\frac{y_{2}- y_{1} }{x_{2} -x_{1} } \\m= \frac{-2-2}{3-6}\\ =\frac{-4}{-3}\\ =\frac{4}{3}$

The standard form of equation of a line is:

y = mx + b

We know m,

So the equation will be:

$y= \frac{4}{3}x+b$

We have to find the value of b, for that we will put any one of the point in the equation

So, putting (6,2)

2 = 4/3 * 6 + b

2 = 8 +b

b = -6

Putting the value of m and b in the standard form of equation of line,

$y = mx + b\\y = \frac{4}{3}x+(-6)\\y = \frac{4}{3} x - 6\\Multiplying\ both\ sides\ by\ 3\\3y = 4x - 18\\4x - 3y -18 = 0$ ..

Answer:

A table that has (0,0), (-1,1), (-4, 2) and undefined for any positive x value

Step-by-step explanation:

Reflecting across the y axis just changes the x values, it makes them negative. so $\sqrt{x}$ has points (0,0), (1,1), (4, 2) and so on. reflecting over the y axis makes them(0,0), (-1,1), (-4, 2) and again so on.

Also good to mention in $\sqrt{x}$ negative x values are undefined, so flipped over the y axis positive x values are undefined.

As for the answer it doesn't look like any of those shown. The first one is close, but the x values would need to swap their signs.
