Which of the following most accurately describes why trade-offs are necessary?

A. There are easily overlooked associated costs for many purchases.
B. The raw material for every good in the product market came from the input market.
C. Any choice involves sacrificing the alternatives that could have been chosen.
D. Nearly all the factors of production are final goods.
E. A portion of all business revenue must be spent on production costs.

This is a system of three equations with two unknowns, x and y. To solve it, we can use the method of elimination. First, we can eliminate y by subtracting the first equation from the second equation:

x^2-2y=3 - (x-2y=3) => x^2-x=0

Then we can factor the resulting equation and find the values of x:

x^2-x=0 => x(x-1)=0 => x=0 or x=1

Next, we can substitute these values of x into any of the original equations and find the corresponding values of y. For example, using the first equation:

x-2y=3 => 0-2y=3 => y=-3/2 when x=0 x-2y=3 => 1-2y=3 => y=-1 when x=1

Finally, we can substitute these values of x and y into the expression x2y-2xy2 and evaluate it:

x2y-2xy2 => 02(-3/2)-2(0)(-3/2)2 => 0 when x=0 and y=-3/2 x2y-2xy2 => 12(-1)-2(1)(-1)2 => -3 when x=1 and y=-1

Therefore, the value of x2y-2xy2 can be either 0 or -3 depending on the values of x and y.

Answer: I think 100 elves. The question isn´t really complete.

Answer:

1A= 36 degrees for the 2 equal length sides.

1B= They stay the same because even though the size of the triangle is increasing, the angle measures would stay the same.

2A= he is incorrect, that would be counted as a "slide" or a translation. The translation would be the movement of the triangle from one location (black triangle) to the next (blue triangle) without changing the size, or orientation

2B= yes. It is congruent because all sides and angle measures remained the same, throughout the transformation.

Answer:

1. a. 36° for the 2 equal length sides.

   b. The angle measures of the triangle will stay the same.  

2. a. Bart is incorrect. The picture illustrates a "shift" or a translation.  

    b. The two figures are congruent since all sides and angle measures are the same.

The answers is: 33

33 is the integer that represents her location relative to the surface after 7 seconds.

And 33 feet far the diver have to go to return to the surface.

Step-by-step explanation:

Given:

A scuba diver is 15.5 feet below the surface of the water.

The diver continues to swim downward at a rate of 2.5 feet per second.

Now, to find the integer represents her location relative to the surface after 7 seconds.

And to find how far does the diver have to go to return to the surface.

So, to get the integer represents her location relative to the surface after 7 seconds.

Initial depth = 15.5 feet.

Distance traveled down = 7 × 2.5 = 17.5 feet.

Final depth of water surface = Initial depth + Distance traveled down.

Final depth of water surface = 15.5 feet + 17.5 feet.

Final depth of water surface = 33 feet.

Thus, 33 is the integer represents her location relative to the surface after 7 seconds.

Now, to get how far does the diver have to go to return to the surface:

As, the diver goes to 33 feet down to the surface.

Thus, the diver to return she have to go through the same distance.

So, to return to the surface she need to go to 33 feet far.

Therefore, 33 is the integer that represents her location relative to the surface after 7 seconds.

And 33 feet far the diver have to go to return to the surface.

Answer:

D is the right choice and no you cannot fit the pizza inside the box.

Step-by-step explanation:

D is the answer because to turn 2/3 into a decimal you would divide 2 by 3 and the answer you would get would be 0.66666666666...You would then add 12 to the answer and get 12.6666... Once you get this answer you would round it to the hundredths to get 12.67 but since that is not an option you could use D, 12.66 inches.

Answer:

I believe the answer is D.

Answer:

46C°

Step-by-step explanation:

The difference can be found as follows

\(Difference = |T_1-T_2|\\Difference = |-126-(-172)|\\\therefore Difference = |46|=46C\degre\)

Answer:

46 Celsius

Step-by-step explanation:

-172 + x = -126

x = -126 + 172

x = 46 Celsius

Answer:

1/2 or 0.5.

Step-by-step explanation:

To calculate the probability of two cards chosen not including T, we need to determine the number of favorable outcomes (cards not including T) and the total number of possible outcomes.

From the provided sample space table:

The favorable outcomes for two cards not including T are:

P, M

P, P

P, R

P, M

R, M

R, P

R, R

R, T

There are 8 favorable outcomes.

The total number of possible outcomes is the number of cells in the table, which is 16.

Therefore, the probability of two cards chosen not including T is 8/16, which simplifies to 1/2 or 0.5.

Answer: 9/16

Step-by-step explanation:

hopefully (i think)

16 total options

9 don't include a T

so 9/16 don't include T

9/16 also don't include M, so they have equal probabilities, which makes sense since there are an equal number of each letter card

Answer:

variable: number of hours

inequality (unsimplified): 4x+3 > 2x+10

inequality (simplified): x > 3.5

at least 4 hours

Step-by-step explanation:

we can use mx+b to solve this. m will be the rate at which the water level rises and b will be your stating point. x defines the hour; this is your varible as it can change

Tank A: 4x+3

Tank B: 2x+10

since we want to find when tank a will have be deeper than tank b, we set the inequality to solve for greater than tank a: 4x+3 > 2x+10

subtract 3 to both sides: 4x > 2x + 7

subtract 2x to both sides: 2x > 7

divide both sides by 2: x > 3.5

Answer:

1) does k = 1

2) does k = -0.8

3) does k = 1

4) does not

Step-by-step explanation:

1) plot the point and solve the line to get y = x-2 so k = 1

2) plot the point and solve the line to get y = -0.8x so k = -0.8

3) plot the point and solve the line to get y = x + 9 so k = 1

4) plot the points and theres no straight line that goes through the points so it does not show a proportional relationship

Answer:695 pillow

Step-by-step explanation:

You have 395 pillows, and then 3 shipments of 100 pillows come in. 3 shipments x 100 pillows = 300 pillows

395 pillow + the 300 new ones = 695 pillows.

Answer: 695

Step-by-step Explanation: They started with 395 then got three shipments that add up to 300 so 395 + 300 = 600
