Answer:

(-7, 5)

Step-by-step explanation:

Since both of them are equal to y, you could just set them equal to each other.

5/7x + 4 = -1/7x - 2

6/7x = -6

x = -7

Now just plug x back to one of the equations:

y = -1/7*(-7) - 2 = 7 - 2 = 5

Therefore, the solution to the system is (-7, 5)

 Can someone plz help me What is the surface area of the figure?     A. 408 ft2   B. 458 ft2   C. 545 ft2   D. 720 ft2
AveGali [126]
There are 2 faces 7 x 5

2*(5*7)=2*35=70ft^2

There 2 faces 5 x 5

2*(5*5)=2*25=50ft^2

there are 3 faces 5 x 12

4*(5*12)=4*60=240ft^2

There are 2 faces 7 x 7

2*(7*7)=2*49=98ft^2

Now only we have to sum all of them together

98+240+50+70=458ft^2

A 48 in, by 36 in. poster is reduced to an image that is 8 in. by 6 in. in size to be used for a flyer. What is the scale factor
Aliun [14]
Divide the original size by the reduced size:

48 / 8 = 6
36 / 6 = 6

Both sides were reduced by the same amount, and because the image was made smaller the scale factor would be a fraction less than 1.

The scale factor would be 1/6

The answer is B.

The Mountain Springs Water Company has two departments, Purifying and Bottling. The Bottling Department received 58,000 liters f
SashulF [63]

Answer:

52,000 liters.

Step-by-step explanation:

We know that the Bottling Department completed 56,000 liters, but this is not the total amount of production started and completed, because there are 4,000 liters that are equivalent to work-in-process. In other words, those 4,000 liters equals a partially finished product that is awaiting further processing.

Because we want to know what the final finished product is, we simply subtract these 4000 liters.

Mathematically:

L = 56,000 - 4,000

L = 52,000
