7 Find the slope of the line that passes

Mathematics
1 answer:
Free_Kalibri [48]3 years ago
3 0

Answer:

y=1.6x+7.2

Step-by-step explanation:

First you want to find m or the slope so use the formula m=y2-y1/x2-x1 and you get your slope which is 1.6.

Then you plug in your slope to the equation including another coordinate or example (3,12) plugged in to make 12=1.6(3)+b. Now you can solve for b.

Once you do that you get b=7.2

So now with m=1.6 and b=7.2, you can finally make the equation.

y=1.6x+7.2

Find a bijection from (0,1] to (0,1)<br><br> Math: Analysis and proof
gregori [183]

Answer with explanation:

The meaning of bijection for two sets X and Y is each and every element of X is uniquely related with element of set Y and when you take the inverse mapping every element of set Y is uniquely related with each and every element of Set X.

The two sets given are

X=(0,1]---------Semi open or Semi closed Set

Y=(0,1)---------Closed set

Between any two real numbers there are infinite number of real numbers.So cardinal number of both the sets is infinite.

There can be infinite bijection between these two sets as both sets have infinite number of elements.

   X                      Y

0.1  -------------      0.01

0.2     -------          0.02

0.3     --------         0.03

0.4     ---------          0.04
