To manufacture 30 items, it costs $2700, and to manufacture 50 items, it costs $3200. If x represents the number of items manufactured and y the cost, write the cost function.

a. Y= -25X + 4450
b. Y = 500 X 21,800
c. Y = 0.04X + 3198
d. Y = 25X + 1950

Answer:

Fourth

5/3

Step-by-step explanation:

Answer:

There would be a 56% increase

Step-by-step explanation:

We need to find the amount of change before we can find the percent of change. We'll take the greater value, 78, and subtract the lesser value, 50. 78 - 50 = 28. We then take this amount of change and put it over the original amount, Percent of change = Amount of change/ original amount or for this problem, 28/50. We then use that as a division equation for 28 divided by 50. 28 divided by 50 = 0.56. Finally we move the decimal to the right two times and we can then find the percentage increase.

Answer:

8/15 of Jayda's vegetable garden are beefsteak tomatoes.

Step-by-step explanation:

Since Jayda has a vegetable garden, of which 2/3 are tomato plants, and of these tomato plants 4/5 are beefsteak tomatoes, to determine the portion of the garden that is made up of beefsteak tomatoes the following must be done mathematical reasoning:

The common least multiple of 3 and 5 is 15, so 2/3 can be re-categorized as 10/15. In turn, of those 10, 4/5 are beefsteak tomatoes, which can be re-categorized as 8/10.

Therefore, 8/15 of Jayda's vegetable garden are beefsteak tomatoes.

I say D cuz if u look at it, it's a pretty wide enough angle to be at least 47°

Answer:

your answer is c

Step-by-step explanation:

for it to be 137 degrees, the line would have to change direction to get to that angle, and same with the others, and with 43 degrees, it already gives you the measurement of  N F so you can just take that same angle and put it there as your answer.

Answer:

Stohr sequence

Step-by-step explanation:

Let a_1=1 and define a_(n+1) to be the least integer greater than a_n which cannot be written as the sum of at most h>=2 addends among the terms a_1, a_2, ..., a_n. This defines the h-Stöhr sequence

Answer:

( 4 , 1 )

Step-by-step explanation:

when canceling out the y values and then adding the two functions together you get

7y = 7

dividing by seven you get y = 1

when plugging y = 1 into the first quation you get

5 - 4x = -7

subtract 5 from both sides

-4x = -12

divide both sides by negetive four

x = 3

then with plugging in y = 1 for the second equation you get

2 + 4x = 14

subtract 2 from both sides

4x = 12

divide both sides by 4

x = 3

you then check your answers and get the point of (4, 1) for your answer.

Answer:

$0.90

Step-by-step explanation:

Answer:

$0.90

Step-by-step explanation:

Assuming there are no taxes or additional costs, one simply has to divide the total cost by the amount purchased to find the unit price, hence;

2.7 / 3

= 0.9

Answer:

No

Step-by-step explanation:

Assuming that you put the wrong sign for the second equation if you plug (2,7) into the two equations it only works for one equation.

Answer:

Every number in decimal form, in which either decimals terminate or certain numbers after decimal point continue to repeat endlessly, can be written as a fraction. As the given number 4.5 terminates after first deciimal it can be written as fraction. Here we have 4.5=4510=92 a fraction.

The equation of the perpendicular bisector line

5 x - 2 y + 31 =0

Step-by-step explanation:

Explanation:-

Given points are ( 0,1) and (-10,5)

The Midpoint of given two points

             [tex](\frac{x_{1}+x_{2} }{2} , \frac{y_{1}+y_{2} }{2} )[/tex]

             (-5 , 3)

The Slope of the line

 m =        [tex]\frac{y_{2} -y_{1} }{x_{2}-x_{1} } = \frac{5-1}{-10} = \frac{-2}{5}[/tex]

The perpendicular slope

    =   [tex]\frac{-1}{m} = \frac{-1}{\frac{-2}{5} } = \frac{5}{2}[/tex]

The equation of the perpendicular bisector line

 [tex]y - y_{1} = m (x - x_{1} )[/tex]

 [tex]y - 3 = \frac{5}{2} ( x-(-5))[/tex]

  2 y - 6 = 5( x +5)

    5 x + 25 -2y +6 =0

   5 x - 2 y + 31 =0
