Refer to the equation 2x − 3y = 18.

Mathematics

First, you should rearrange your equation using simple algebra

2x-3y-18=0
2x-18=3y
(2x/3)-6=y

the y intercept has an x coordinate of 0, so substitute 0 as x in your equation to find the y-int.

the x intercept has a y coordinate of 0, so substitute 0 as y in your equation and algebraically solve for the x-int

to make the table of values, just substitute different values in for x in the equation

Find the median of the following data : 9, 15, 17, 18,6, 20, 8, 5, 18, 18, 10, 5, 14, 12, 10, 7
stellarik [79]

Answer:

The median of the data is 12.

Step-by-step explanation:

The median is really just another word for the average. To find that, you add all of the numbers and divide that sum by the number of numbers there are.

9+15+17+18+6+20+8+5+18+18+10+5+14+12+10+7=192

There are 16 numbers in this data set. So, we will divide the sum by 16.

192÷16=12

I hope this helps!! :)

I need to know the distance and if your could please tell me the formula for future problems thank you!! ASAP
Ksivusya [100]

Distances in 2- and 3-dimensions (and even higher dimensions) can be found using the Pythagorean theorem. The straight-line distance can be considered to be the hypotenuse of a right triangle whose sides are the horizontal and vertical differences between the coordinates.

Here, you have A = (0, 0) and B = (3, 6). The horizontal distance between the points is ...

... 3 - 0 = 3 . . . . the difference of x-coordinates

The vertical distance between the points is ...

... 6 - 0 = 6 . . . . the difference of y-coordinates

Then the straight-line distance (d) between the points is found from the Pythagorean theorem, which tells you ...

... d² = 3² + 6²

... d = √(9 + 36) = √45 ≈ 6.7 . . . units
