Waterway Industries has fixed costs of $15,000 per year. Its warehouse sells wine with variable costs of 70% of its unit selling
vampirchik [111]

Answer:

50000 units sale per dollar price of the wine

Step-by-step explanation:

Fixed cost per year = $15,000

Variable cost per bottle of wine = 70% of selling price

To break even, the profits from the number of units sold = $15,000

(30% of selling price)× X units =$15,000

Or 15,000÷0.3 =50000 units per dollar price of wine

Evaluate: [(- 16) + 4] ÷ [(-2) + 5]
Tresset [83]

Answer:

We need to evaluate this: [(-16)+4] / [(-2)+5]

First, we do the brackets:

  • [(-16)+4]
  • [(-2)+5]

[(-16)+4] = -16 + 4 = -12

[(-2) + 5] = -2 + 5 = 3

Now, we only need to divide, as we have calculated both brackets:

-12/3 = -4

(Remember that when dividing a negative number by a positive one, we always obtain a negative)

So the result is -4

What is the slope intercept of the equation of the line through the given point (0,3) and (-4,-1)
cestrela7 [59]

Answer:

y=x+3

Step-by-step explanation:

1.) Find slope

slope = (-1-3)/(-4-0)

= -4/-4

= 1

2.) Use point slope form

<u>y-y1= m (x-x1) </u>

both x1 and y1 are the points

m is the slope

3.) Plug in the numbers

for the points I chose (0,3) to plug in

y-3= 1 (x1-0)

y-3= x

y= x+3

Which is the slope of the line that passes through the points (3,5) and (8,7)?
Hatshy [7]

Hi there!  

»»————- ★ ————-««

I believe your answer is:  

m=\boxed{\frac{2}{5}}

»»————- ★ ————-««  

Here’s why:  

  • The formula for the slope of two given lines given is 'rise over run'.

⸻⸻⸻⸻

\boxed{\text{Slope Formula:}}\\\\\frac{y_2-y_1}{x_2-x_1}\\\\\rightarrow (x_1,y_1),(x_2,x_1) - \text{Two Points Given}

⸻⸻⸻⸻

  • We are given the points (3,5) and (8,7).

⸻⸻⸻⸻

\boxed{\text{Finding the Slope:}}\\\\\rightarrow m=\frac{7-5}{8-3}\\\\\rightarrow \boxed{m=\frac{2}{5}}

⸻⸻⸻⸻

»»————- ★ ————-««  

Hope this helps you. I apologize if it’s incorrect.
