NOT A MULTIPLE CHOICE QUESTION, I NEED AN ANSWER FOR ALL!!!I. The Bread Machine (25 points)
In real life, you must often make choices about whether to buy something pre-made or make it yourself. There are many things to consider: quality of homemade vs. bought, expense, convenience, enjoyment of making something, etc. In this response, you will be looking at the choice of buying a bread machine or relying exclusively on store bought bread.

A. The bread machine you are interested in costs $100 with tax.
The ingredients to make one loaf of bread cost $0.80.
What is the rate of cost of one loaf of bread?

B. What is your start up cost? (cost of machine)

C. Write a linear equation, y = mx + b for the total cost.

D. Graph the equation on the graph provided. You may use either Point Plotting or Slope-Intercept. Be sure to locate at least 3 points. You may want to do this in pencil in case you decide to use more points later in the problem.

Answers

1. The decision you're looking at is buying a bread machine and the ingredients to make bread vs buying bread at the store.

B. What is your start up cost (cost of machine)?
$100

C. Write a linear equation for the total cost in form, y = mx + b.
Total cost is the cumulative cost for all loaves of bread since the machine was purchased.
You have the start-up cost plus the cost of each additional loaf of bread, so the total cost (Y) is:
Y = $100 + $0.80*x
where x is the number of loaves of bread.

D. Graph the equation on the graph provided.

How are parallelogram related to triangles and rectangles

Answers

Parallelograms are related to trailed because you can divide the parallelogram into triangles by adding diagonals lines in it.

They are related to rectangles because the parallelogram is just tilted a little

Mike wants to make meatloaf. His recipe uses a total of 5 pounds of meat. If he uses a 3 to 1 ratio of beef to pork, how much pork will he use?

Answers

Ratio of beef to pork = 3 : 1

Beef:Pork = 3 : 1

Total ratio = 3 + 1 = 4

Amount of pork: Fraction of Pork = 1/4 of the whole meat

(1/4)*5 = 5/4 = 1.25

Amount of Pork = 1.25 pounds.

Hope this explains it.

The sum of three consecutive even integers is 72. Let x represent the first integer, x + 2 represent the second integer, and x + 4represent the third integer.
Which equation can be used to find the first integer?
0 3x + 6 = 72
0 3х + 72 = 2х +6
03x = 2х +6
2x + 64 = 72

Answers

Answer:

3x + 6 = 72

Step-by-step explanation:

x + x + 2 + x + 4 = 72

What is the simplified form of x minus 5 over x squared minus 3x minus 10 ⋅ x plus 4 over x squared plus x minus 12? (6 points)

Answers

Answer: Our simplified form will be

$(1)/((x+2)(x-3))$

Step-by-step explanation:

Since we have given that

$(x-5)/(x^2-3x-10)* (x+4)/(x^2+x-12)$

So, first we split the middle term of the denominator ,

$x^2-3x-10=0\n\n=x^2-5x+2x-10\n\n=x(x-5)+2(x-5)\n\n=(x-5)(x+2)$

Similarly,

$x^2+x-12=0\n\nx^2+4x-3x-12=0\n\nx(x+4)-3(x+4)=0\n\n(x+4)(x-3)=0$

Now, we put in our expression above:

$(x-5)/((x-5)(x+2))* (x+4)/((x-3)(x+4))\n\n=(1)/(x+2)* (1)/(x-3)\n\n=(1)/((x+2)(x-3))$

Hence, our simplified form will be

$(1)/((x+2)(x-3))$

Step 1 is to factor everything!

After factoring you will get:

x-5 over (x+2)(x+5) times x+4 over (x-3)(x+4)

Step 2 is to remove the duplicate factors!
Remove x+4 and x+5

x-5 over (x+2)(x-5) times 1 over x-3 = 1 over x+2 times 1 over x-3

Step 3 is to multiply the numerators and the denominators.

End result is 1 over (x+2)(x-3)
