How menu terms are in the arithmetic sequence 7,0,-?

27 terms

Step-by-step explanation:

Here the first term is 7 and the common difference is -7.  Each new term is equal to the previous term, less 7.

The general formula that involves first and last terms, common difference and number of terms is    last = first + (n - 1)(common difference)

We substitute the knowns, as follows:

                                           -175 = 7 + (n-1)(-7)

Solve this first for n-1, and then for n:

Subtract 7 from both sides:   -182 = - 7(n-1)

Dividing both sides by -7 yields  26 = n - 1

Then n = 27.

There are 27 terms in this arith. sequence.

dude thats to long figure it

step-by-step explanation:

when rotating a figure 180 degrees, imagine that you are able to take the figure and turn it clockwise or counterclockwise around a center point. to rotate a figure 180 degrees, you will need to apply the rule (x, y) → (-x, -y). start by using a coordinate grid with coordinates for each vertex of the figure. the center point of the coordinate grid is located at (0, 0), which is what you will rotate the figure around. write down the original coordinates of the shape you are going to rotate. then, apply the rule. for example, coordinate (1, 2) becomes (-1, -2). another example would be, coordinate (-4, -2) becoming (4, 2). after you change each original coordinate to the rotated coordinate, you will draw your new figure.
