devlian [24]

It's forming an A. P. because each succeeding Te rm increases by a common value i. e. 6 here.

The A. P is

22,28,34,.....

So the n th term will be represented as

a+(n-1)d,

where a=22

And d=6

Now in (b) part the n th term is given i. e. 100

So by putting in the given values we could easily found the value of n

n=(100-22)/6=78/6=13

So the 13th term will be 100

Hope You Got It.

Multiple Representations Explain how to use a number line to find the
DaniilM [7]

Answer:

First, 3 units away from -7 could be, either -10 (when going to the left), or -4 (moving 3 to the right). Lastly, the opposite of the integer(s), (if opposite is meaning, if the third number is -10, then the "opposite" could be the positive number "10".? and/or the other third integer is -4, then the "opposite" could be its positive, or absolute value of the negative number, or just "4".  i.e. If given a " -4", then the absolute value of it is, +4.  Or, also can be written, |-4|, meaning, the absolute value of -4, equals +4, or 4.

Step-by-step explanation:

Draw a line straight across your paper (from left to right), then in the middle of the line, make a little mark straight up and down and label it 0 (zero).  To the right, each little mark made through the line, will be positive, and go up from zero "0" to 1, then 2, then 3, then 4, and so on... Usually making a standard size number line, mark and count up to about "10".

Next, from the middle "0", moving to the left, making small marks through the line, counting from "0", to 1, and 2 and 3 and so on, EXCEPT making all these numbers negative, until getting to "-10" on the number line.

Please help me in Geometry!

Answer:

You get an perpendicular line through given point.

Step-by-step explanation:

In this method of drawing perpendicular line through given point,

you will draw an arc from given point R, so as to cut given line at A and B.

now ,length RA will be equal to length RB (radius of circle)

now, with length RA you will place compass at A and B to cut the arcs at point P (let) on other side of given line.Now, join PA and PB.  

The closed RAPB makes a rhombus and diagonal bisect perpendicularly in rhombus.

so you get an perpendicular line through given point.
