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

Korvikt [17]

Answer:

The number of books produced at which the costs from the two methods be the same is 4668 books

Step-by-step explanation:

Here, we have

For the first production method

Fixed cost = $65,054 and variable cost per book = $8.25

For the second production method

Fixed cost = $12,539 and variable cost per book = $19.50

Therefore, let the number of books at which the to methods cost the same be M, we then have

$65,054 + $8.25 × M = $12,539 + $19.50× M

Which gives

$65,054 - $12,539 = $19.50× M - $8.25 × M

$52515 = $11.25 × M

M = $52515/$11.25 = 4668 books.

babunello [35]

Answer:

y = - 2x - 4

Step-by-step explanation:

the equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

calculate m using the slope formula

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

with (x₁, y₁ ) = (- 2, 0) and (x₂, y₂ ) = (0, - 4) ← 2 points on the line

m = $\frac{-4-0}{0-(-2)}$ = $\frac{-4}{0+2}$ = $\frac{-4}{2}$ = - 2

the line crosses the y- axis at (0, - 4 ) ⇒ c = - 4

y = - 2x - 4 ← equation of line

Which expression belongs in the box?

MakcuM [25]

Answer:

The expression that belongs in the box is 8 x 4

Option C is correct answer.

Step-by-step explanation:

We need to find Which expression belongs in the box?

$(3 \times 8) \times 4= 3 \times (------)$

The property applied here is associative property of multiplication.

Associative property of multiplication states that:

$(a \times b)\times c = a \times (b \times c)$

So, if we apply the property to our question we have:

a = 3

b = 8

c = 4

So, the expression will become: $(3 \times 8) \times 4= 3 \times (8 \times 4)$

So, the expression that belongs in the box is 8 x 4

Option C is correct answer.

otez555 [7]

Answer:

-6 ≥ x

Step-by-step explanation:

x + 6 ≥ 12 + 2x

Subtract x from each side

x-x + 6 ≥ 12 + 2x-x

6 ≥ 12 + x

Subtract 12 from each side

6-12 ≥ 12-12x

-6 ≥ x
