Answer:

The third answer (C).

Step-by-step explanation:

This graph starts at 10. So it needs the +10 at the end.

Also the slope is -1/2 because the graph goes down one, right two. Rise/run.

Whoever answers this can you please like show how you did it Idk how to do it

Answer:

a) 2500 L b) 2250 L c) 98000 L d) 14.5 kg of rice, .725 kg of beef, 48.3 repeating kg of wheat.

Step-by-step explanation:

Ok so, this question looks intimidating but I promise it's not that bad.

a) They're asking how much water (L - meaning liters) would be needed for 25 baths.

To find this, they already give you how much water is needed for 1 bath. (100) Since this is the amount for 1 bath, we can find how much water is needed for 25 baths by multiplying 100 by 25. Your answer should be 2500 L of water.

b) This is the same thing again, but with wheat. They give us the information for how much wheat is used for 1 kg of wheat, which is 600 L. The question asks how much water would be needed to produce 3.75 kg of wheat, so we multiply 600 by 3.75 which equals 2250 L.

c) This is also the same thing but this time for beef. So we multiply 40000 by 2.45 which gives us 98000 L

d) To find this, we must divide 29,000 by the amount of water needed for 1 of each item, so we can find how much we would multiply the amount needed for 1 of each item in the first place (which is the amount of rice, beef, wheat)

So, 29,000/2000 = 14.5 kg of rice

29,000/40000 = .725 kg of beef

29,000/600 = 48.3 repeating kg of wheat.

The slope of Consider the line whose equation is 3x + y - 3 = 0. The slope of any line that is parallel to this line is any line
PSYCHO15rus [73]

Answer:

parallel : y = -3x + 3

perpendicular : y = 1/3x + 3

Step-by-step explanation:

rewrite 3x + y - 3 = 0

y = -3x + 3

parallel has the same slope

so

parallel : y = -3x + 3

perpendicular is negative reciprocal of the slope

so

-3x becomes 1/3x

so

perpendicular : y = 1/3x + 3

Please Answer ASAP, Thx! 5x -2y=17 and 4x - 3y= 8
iVinArrow [24]

5x - 2y = 17

4x - 3y = 8

Try to change one of the equations to isolate a variable, so you can use the new equation and substitute it into the other equation.

5x - 2y = 17

-2y = 17 - 5x

y = -17/2 + 5/2x

Now plug this into the second equation

4x - 3(-17/2 + 5/2x) = 8

4x + 51/2 - 15/2x = 8

8/2x - 15/2x = 16/2 - 51/2

-7/2x = -35/2

x = 5

Plug this into either equation to find y

4x - 3y = 8

4(5) - 3y = 8

20 - 3y = 8

-3y = -12

y = 4


x = 5, y = 4
