Answer:

  • c = 5.25n +600
  • meal cost: $5.25; membership fee: $600
  • $1335

Step-by-step explanation:

a. Using the variables defined for you, there are two points given:

  (n, c) = (100, 1125) and (160, 1440)

You can use the 2-point form of the equation for a line to find the desired linear function:

  y = (y2 -y1)/(x2 -x1)(x -x1) +y1 . . . . when given points (x1, y1), (x2, y2)

  c = (1440 -1125)/(160 -100)(n -100) +1125 . . . fill in given values

  c = 315/60(n -100) +1125

  c = 5.25n +600

__

b. The cost of each meal is the amount by which the total cost goes up when the number of meals goes up by 1. That is the coefficient of n, 5.25. The membership fee is the cost of 0 meals, 600.

The cost of each meal is $5.25; the membership fee is $600.

__

c. For n = 140, the cost is ...

  c = 5.25(140) +600 = 735 +600 = 1335

The cost of 140 meals is $1335.

Brums [2.3K]

Answer:

  4^2 + (-7)^2

Step-by-step explanation:

The square of the distance is given by the distance formula as ...

  d^2 = (x2 -x1)^2 + (y2 -y1)^2 = (3 -(-1))^2 + (-5-2)^2

  = 4^2 +(-7)^2 . . . . . matches the second choice (sort of)

_____

<em>Comment on notation</em>

Clearly, you understand the use of the caret (^) to signify exponentiation. The number 42 is very different from the value of 4^2 = 16. A caret is required.

If m∠4= 138°. Find m∠1, m∠2, and m∠3. <br> please explain how to work this out
Gekata [30.6K]
The opposite angles are equal so m4=m1 and m2=m3. If you know m4=m1, m1= 138 so m4+m1= 276. That means m2 and m3 are equal to 84 in total. Your answer should be 48 for both m2 and m3 cuz they add to 84
