How do you decide where to shade an inequality whose boundary dose not go through the origin?
A. For <, shade above the boundary
B. If (0,0) is a solution, shade where (0,0) is
C. For >,shade below the boundary
D.If (0,0) is a solution, shade the boundary.

Answers

Answer 1

Answer:

I’m pretty sure that it is D because it says boundary and not just where it is at.

Step-by-step explanation:

If you have an equation for your graph you would substitute the y AND x with 0, you the solve the solution and if the solution is true then the space where (0,0) is located becomes the shaded area because that resembles the area in which everything is a positive solution with the equation. If it is false then the opposite area is then shaded because (0,0) doesn’t work with the problem.

I hope you get it right! Have a good week :D

A restaurant sells burritos for $8.00 each. The cost of the meat is $1.50 and the cost of the other ingredients is $1.00 for each burrito. Money made from selling burritos is positive. The cost of making burritos is negative. Profit is the money left after paying the costs.

How much profit would the restaurant make by selling 100 burritos?


What is the cost of making one burrito? (Remember that costs are negative.) Explain how you found your answer.




Write your answer in the space below.

Answers

Answer:

Profit for 100 burritos: $550

Cost to make one burrito: $2.50

Step-by-step explanation:

If a restaurant sells burritos for $8, that's a positive 8 dollars they earned. Then, we need to find what the cost was to make the burrito. If the meat is 1.50 and the cost for all the other ingredients is 1 dollar, then they lose 2.50 for every 8 dollars they make (for each burrito). So, to find the profit in one burrito, we would add -2.5+8, giving us an answer of 5.5. So, they earn 5 dollars and 50 cents each burrito and lose $2.50.

Now, we need to find the profit of 100 burritos

If one burrito is $5.50 in profit, then we take that amount and multiply it by 100. This is to make the illitsratution of selling 100 burritos. So, 5.50*100 would be 550! They would make $550 for 100 burritos, and lose 250 dollars on all of the burrito ingredients.  

the answer is 550 and 2.50

Can you show more information please?

Answer:

Using technology, the linear regression equation which models the data of the relationship between the number of customers served and tips received is :

y = 1.87x + 3.66

predicted amount of tip for 100 customers = $191

The predicted amount of tips received of 100 customers are served :

y = 1.87x + 3.66

x = 100 ; substitute x = 100 into the equation

y = 1.87(100) + 3.66

y = 187 + 3.66

y = 190.66

Hence, about $191 would be received on tips if 100 customers are recorded.

Using a regression calculator to make prediction from a data table :

Enter the x and y axis data into the appropriate column so that the calculator can display the actual data model. Hence, given a certain value of either variable, the predicted value of the required variable can be calculated from the model.

Answers

Answer:

yes every values are increasing constantly by 2.5

Answer:

Step-by-step explanation:

Note that for each unit increase in x, y increases by 2.5.  The constant of proportionality is therefore 2.5:

y = 2.5x

All of the y-values are a constant multiple of the corresponding x-values, so the relationship is a proportional one.

Graph the solution to this inequality on the number line. −1/3x + 1/2 ≥ −3/4

Answers

Answer:

4.5 (4.5 units to the left of 0) Make sure to draw a solid dot over 4.5 and an arrow pointing in the right direction.

>= is the greater than or equal to symbol

Step-by-step explanation

1. Combine like terms- In this problem, the like terms are 1/2 and -3/4, so to move 1/2 over to the other side of the equation, we have to divide each side by 2/1, which is the same as multiplying each side by 2: -1/3x + 1/2 * 2 >= -3/4 * 2.

2. Separate the fraction from x- Now, we simply divide each side by -3/1, which is the same as multiplying each side as -3: -1/3x * -3 >= -3/2 * -3

3. Graph on the number line- We've found that x = 4.5. To check, substitute in 4.5 for the value of x: -1/3(4.5) + 1/2 >= -3/4. -1 >= -3/4 is a true inequality. To graph it on the number line, draw a solid dot over 4.5 and an arrow in the direction of the righthand side.

8. Multiply the following:

c. (3s^4)(-6s^5)

Answers

The result of the multiplication is (-18s^9).

To multiply the two expressions (3s^4)(-6s^5), you can use the distributive property, which states that you can multiply a term by each of the terms inside a set of parentheses.

Using the distributive property, you can rewrite the expression as:

(3s^4)(-6s^5) = 3s^4 * -6s^5

Then, you can simplify the expression by combining like terms:

3s^4 * -6s^5 = (-18s^9)

So the result of the multiplication is (-18s^9).

Answer = 264m squared.

First the rectangle at the top is 20 x 5 which is 100

To figure out the base of the triangle you would look at the width of the second rectangle and from that you would do 20 - 6 so the base of the triangle is 14

With that you would do 14 x 8 = 112 divided by 2 = 56

The area of the second triangle at the bottom is 108 because 6 x 18 = 108

108 + 56 + 100 = 264m squared (squared because it’s area)

You need 3/4 cup of sugar and your 1/4 is missing
First use the 1/2 cup which is equal to 2/4
Now a tablespoon is 1/16 of a cup, so use 4 table spoons, which is 1/4 of a cup
