Solve for m y-y=m(x-x)
spin [16.1K]

Answer:

m = y/x

Step-by-step explanation:

y-y = m(x-x)

simplify:

-2y = m(-2x)

simplify again

-2y = -2mx

divide to get rid of -2 and x

-2y = -2mx

----------------

-2x

y

-  = m

x

How many area codes (abc) would be possible if all three digits could be any vaiue 1-9
kifflom [539]

Answer:

<u>The total number of area codes that would be possible if all three digits could be any value from 1 to 9 is 729.</u>

Step-by-step explanation:

1. Let's start our reasoning to get this answer:

From 000 to 999, we have 1,000 possible area codes.

But for this question, we should find out the answer without considering the digit 0, therefore we must exclude:

A. From 000 to 099, that are 100 possible area codes.

B. We also have to exclude, from 100 to 110, 120, 130, 140, 150, 160, 170, 180 and 190. Those are 19 area codes more.

C. We also have to exclude these same options of code areas, for 200 - 210 and 2x0, and 19 more for each subset that starts with 3, 4, 5, 6, 7, 8 and 9. In total, 19 multiplied by 8, 152 numbers more.

<u>Therefore, the total number of area codes that would be possible if all three digits could be any value from 1 to 9 is:</u>

<u>1,000 - 100 - 19 - 152 = 729</u>

<u>The simplest way to find it, is:</u>

<u>For 000 to 999 = 1,000 or 10³</u>

<u>Excluding the digit zero = 729 or 9³</u>

A biologist created the following graph to show the relationship between the temperature of water (x), in degrees Celsius, and t
Hoochie [10]

Answer:

<em>A.</em><em> There were 400 larvae at 0 degree Celsius.</em>

Step-by-step explanation:

Here,

x = the temperature of water in °C

y = the number of insect larvae in the water

The graph is a graph of quadratic function as it is a parabola and it opens downward, so it has a negative leading coefficient i.e coefficient of x² is negative.

At y intercept, the line or curve passes through y axis. At y intercept the value of x is zero, because on y axis the value of x is 0.

As the y intercept in this case is (0, 400), so at y intercept value of x is 0 and y is 400.

Therefore, at y intercept or at 0°C there were 400 larvae.
