Mathematics

Mandarinka [93]3 years ago

5 0

Answer:

11 feet

Step-by-step explanation:

First, convert all the mixed fractions to improper fractions in the a/b form.

4 1/2 becomes 9/2 and 2 1/2 becomes 5/2.

Adding 9/2 to 5/2 we get (9+5)/2, which is 14/2 and that can be simplified to 7.

Finally, adding 7 to 4 we get 11.

So, the sum of the length of all three tables is just 11 feet long.

Hope this helps!

A line passes through the two given points. Is it vertical, horizontal, or neither?

Leviafan [203]

Answer:

A line passes through the two given points (5,2), (5,-2). The line is vertical line

Solution:

Given, two points are (5, 2) and (5, -2)

We have to find that a line that passes through the given two points is vertical or horizontal or neither.

First let us find the slope of the line that passes through given two points.

So, slope of line m $=\frac{y_{2}-y_{1}}{x_{2}-x_{2}} \text { where, }\left(x_{1}, y_{1}\right) \text { and }\left(x_{2}, y_{2}\right) \text { are two points on line. }$

So slope of our line $=\frac{-2-2}{5-5}=\frac{-4}{0}$ = undefined

Here slope of our line is undefined which means it is parallel to the y – axis.

Hence, line passing through given points is vertical line
