The total cost of making a daily taco special for a restaurant is represented by the function C (t) = 2.5t + 1 , where t is the number of tacos made. How does the total cost change for every taco special the food truck makes?
A. The total cost increases by $1.
B. The total cost increases by $2.50.
C. The total cost decreases by $1.
D. The total cost decreases by $2.50.

Answers

Answer:

C. The total cost increases by $2.50

Step-by-step explanation:

This is because 1 dollar is constent--- you will always have 1 dollar.

However 2.5 is the change, you have to times a number to get the answer.

EX:

(t) = 2.5t + 1

(4) = 2.5( 4) + 1 ----- plug in 4 for t

= 10 +1

= 11

The is the multiplyer or change is the 2.5t

and when you graph it it will almost always be the slope of the line.

Please help me! I need to graph this equation but I don't exactly know how.

Answers

Answer:

There would be a y-intercept of one and a slope of -3/4.

Step-by-step explanation:

Negative slope means it will increase going left.

3/4 is the slope 3 rise/ 4 run

the y intercept is 1, so the line will cross the y axis at the 1 point.

1. Find the maximum and minimum values of z = 2x + 3y subject to the following constraints
[tex]0 \leqslant x \leqslant 7[/tex]
[tex]y \geqslant 1[/tex]
[tex]2x - y \geqslant - 5[/tex]
[tex]x + y \leqslant 11[/tex]
Copy and paste the text below and put your answers into the blanks. maximum value =
when x =
and y =
minimum value =
when x =
and y=

Answers

Answer:

Minimum Values:

x = 0, y = 1, z = 3

Maximum Values:

x = 7 , y = 11 , z = 47

Step-by-step explanation:

FOR MINIMUM VALUES:

0<= x <= 7

It is clear from the above inequality that the minimum value of x must be 0.

y>= 1

This inequality shows that the minimum value of y must be 1. Using these minimum values of x and y to get the minimum value of z:

z = 2x + 3y

z = (2)(0) + (3)(1)

z = 3 (Minimum)

FOR MAXIMUM VALUES:

0<= x <= 7

It is clear from the above inequality that the maximum value of x must be 7.

x + y <= 11

To calculate maximum value of y we can use the minimum value of x in this inequality:

0 + y <= 11

y <= 11

Hence, the maximum value of y is 11.

Using these maximum values of x and y to get the maximum value of z:

z = 2x + 3y

z = (2)(7) + (3)(11)

z = 47 (Maximum)

The sum of all angles in a triangle will always add up to 180°. So, because the two triangles are identical, you can do 180-46-82, and get your answer, which is 52°. Have a nice day!

Carmen runs 6 miles in 50 minutes. At the same rate, how many miles would she run in 35 minutes?

Answers

Answer:

4.2 miles

Step-by-step explanation:

6 miles/50 minutes = x miles/35 minutes

1. Since 5 is the GCF (greatest common factor) of x and 35, that is what the ratio must first be converted into, by dividing by 10: 6/50 = 0.6/5

2. To convert this to 35 minutes, it must be multiplied by 7, because 5 * 7 = 35. This leaves us with the answer:

0.6/5 = 4.2 miles/35 minutes

Answer: (2, 19)

Step-by-step explanation:

There are three general ways to solve a system of equations:

- Substitution

- Elimination

- Augmented Matric

Since both given equations all have y isolated, substituting the value of y will be the most appropriate way here.

--------------------------------------------------------------------------------------------------------

Given

y=7x+5

y=x+17

Substitute y into the equations

7x+5=x+17

Subtract 17 on both sides

7x+5-17=x+17-17

7x-12=x

Subtract 7x on both sides

7x-12-7x=x-7x

-12=-6x

Divide -6 on both sides

-12/-6=-6x/-6

x=2

Substitute value into one of the equations

y=x+17

y=2+17

y=19

Answers

Answer:

X is the independent variable

Step-by-step explanation:

I just know

X is the independent variable that represents the independent variable of the function.

What are independent and dependent variables?

Even though everything can be almost always related to its reason, when we talk about two related things, there might happen that one of those things is dependent on other.

If a variable is taking its values independently of any visible direct cause, then that variable is called independent variable.

We are given an expression as y=1/2x-2

Here we can see the variables x and y .

the y intercept is -2.

The slope of the equation is 1/2.

Therefore, we can conclude that the X is the independent variable.

Hamburger meat sells for $6 for every 3 pounds. If Alicia buys 10 pounds of hamburger meat, how much will she pay hamburger meat sells for $6 for every 3 pounds.

Answers

the correct answer will be $20

She'll pay 20$. If the meat is 6$ for every three pounds and she is trying to buy ten pounds, she's going to be purchasing at least nine pounds of the meat. 3x3=9, so 6x3=18. After that she'd still have a pound to pay for. In this case we divide. 3/3=1, so 6/3=2. One pound of meat is equal to 2$. Add 18$ and 2$ and you get 20$

This tune has twenty-four solemn notes, one for each hour of the day, and all the notes are part of a single chord.Taps had its beginnings in Europe. It . . . functioned as a kind of curfew call. It warned [soldiers who were late returning to their barracks] that they had only a short time to return to base. Troops who were roaming at liberty needed to report to their officers, or they would be disciplined.One evening during the Civil War, General Daniel Butterfield, a Union officer, fondly and sympathetically recalled the French tune. Somehow, Taps had crossed the ocean. Butterfield made his speech to his comrades, asking those in the group that the melody be played each evening at sundown instead of a bugle named Extinguish the Lights. The tune soon spread to the Confederate army, and it was even played at the funeral of Confederate General Stonewall Jackson.These days, Taps no longer symbolizes a curfew call. Instead, it functions as a solemn farewell. When its twenty-four notes ring out at a state occasion, mellow and true, they often bring tears to the eyes of the spectators in attendance.What best describes the type of organizational structure used in this passage?A. order of importanceB. chronological orderC. spatial order 10 to the 8 power is what Evaluate 4 ^ x for (a) x = - 2 and (b) x = 3 .
