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.

HELP ME PLSS AND PLSS GET IT RIGHT!
liubo4ka [24]

Answer:

A) 3 or 6

Step-by-step explanation:

120 divided 9 ways means there would be 13 1/3 teams so does not qualify. Any option with 9 as a potential solution is rejected.

120 divided 6 ways means 20 full teams play

120 divided 3 ways means 40 full teams play.

other options could be 2, 4, 5, 8, 10, 12, 15, 20, 24, 30, 60

though the court could get a bit crowded with some of those options.

A typical red blood cell in human blood has a diameter of approximately 0.000007 m. Enter this diameter
pav-90 [236]

Answer:

In scientific notation, that would be;

7.0 * 10^-7 m

Step-by-step explanation:

Here, we want to write the given diameter in scientific notation

Mathematically, that can be done by moving the decimal point to the back of 7

The number of times we move will be counted as negative powers of 10 host

Thus, we have;

7.0 * 10^-7
