pogonyaev

Answer:

15x + 25 = y

Step-by-step explanation:

$25 is a fixed cost and will have to be paid if the plumber comes and $15 times the number of hours it takes to do the repair is the variable cost. 'x' in this case is the number of hours. So the equation will be 15x + 25 = y

A two week old puppy weighs 11 ounces. Two weeks later, it weighs 15 ounces. Right in equation to represent the weight y of the
zhenek [66]

Answer:

  y = 2x +7

Step-by-step explanation:

We are given two points on the growth curve: (weeks, ounces) = (2, 11) or (4, 15).

These can be used to write the equation of a line using the 2-point form:

  y = (y2 -y1)/(x2 -1x)(x -x1) +y1

  y = (15 -11)/(4 -2)(x -2) +11

  y = 4/2(x -2) +11

  y = 2x +7 . . . . . y = weight in ounces x weeks after birth

_____

<em>Comment on the problem</em>

There are an infinite number of equations that can be written to go through the two given points. A linear equation is only one of them.

if the area of the circle measures 9/4 Pi sq cm square what is the circumference of the circle in the terms of Pi
Leto [7]
Pi r squared = area of circle
Pi d = circumference

Therefore 9/4 is the radius squared so the squared root of this is 3/2 (radius)

You then double this to get diameter which is 6/2 or 3 Pi
