The Sugar Sweet Company is going to transport its sugar to market. It will cost $3500 to rent trucks plus $250 for each ton of sugar
transported. The total cost, C (in dollars), for transporting n tons is given by the following.
C = 3500+ 250n

What is the total cost of transporting 15 tons?

In the total cost is $8750, how many tons is the company transporting?

Answers

Answer:  Equation relating C to S   :

The total cost to transport 19 tons of sugar is $11, 250.

Step-by-step explanation:

Given : It will cost $6500 to rent trucks, and it will cost an additional $250 for each ton of sugar transported.

Total cost =  $6500 + $250 x (amount of sugar transported ( in tons))

Let C represent the total cost (in dollars), and let S represent the amount of sugar (in tons) transported.

Then, the equation relating C to S  would be :

When S= 19 , we get

Hence, the total cost to transport 19 tons of sugar would be $11, 250.

Find the three-digit number using the three clues below.

The number 682 shares one digit with the number, and it is correctly placed.
The number 614 shares one digit with the number, but it is wrongly placed.
The number 296 shares two digits with the number, but they are wrongly placed.

Answers

Answer: 942

Step-by-step explanation: this was a tuff one!

Here, we are required to find the three-digit number using the three clues as given.

The three-digit number is 942.

Inference drawn from statements 1, 2 and 3 as follows;

Inference drawn from statements 1, 2 and 3 as follows;The number 682 shares one digit with the number, and it is correctly placed.

Inference drawn from statements 1, 2 and 3 as follows;The number 682 shares one digit with the number, and it is correctly placed.The number 614 shares one digit with the number, but it is wrongly placed

Inference drawn from statements 1, 2 and 3 as follows;The number 682 shares one digit with the number, and it is correctly placed.The number 614 shares one digit with the number, but it is wrongly placed. The number 296 shares two digits with the number, but they are wrongly placed

This means the last digit is 2 as it is present as wrongly placed in statement 3 and it is correctly placed in statement 1.Statement 2 shows that 4 is among the 3 digit number, although it is wrongly placed in the number 614, it can only be the first of the second number.Statement 3 suggests that 9 is the other number present as it is evident from Statement 1 and 2, that 6 is not one of the three-digit number.And since, 9 is wrongly placed in 296, it can only take the first position, thereby leaving the second position to 4.

Ultimately, the three-digit number is 942.

Someone help?!.........

Answers

Answer: y = -2x + 16

Explanation:

Use point slope form:

(y1 - y) = m(x1 - x)

y1 = 6 and x1 = 5 and m = -2

6 - y = -2(5 - x)
6 - y = -10 + 2x
-y = 2x - 10 - 6
-y = 2x - 16
y = -2x + 16

What is the vertex of the absolute value function defined by ƒ(x) = |x - 2| - 7?

(2,-7)
(2,7)
(-2,7)
(-2,-7)

Answers

ExplanationModulus Function

[tex]y = a |x - h| + k[/tex]

The structure or equation is similar to a quadratic function.

The value of a determines the slope of graph.

Tthe value of h determines the horizontal shift of graph.

The value of k determines the vertical shift of the graph.

From the given equation,

[tex]f(x) = |x - 2| - 7[/tex]

We can say that the graph shifts to the right 2 units and shifts down 7 units. Hence the vertex would be at x = 2 and y = -7. It can be written in coordinate form as (2,-7).
