Answer:

Step-by-step explanation:

General arithmetic sequence formula:

where  = first term, and d = common difference.

The first term is -8

And the common difference appears to be - 7 as 7 is subtracted to get to the next term. Ex. -8 - 7 = -15, -15 - 7 = - 22 and so on.

To get the explicit formula of the sequence we simply plug in the values of a1 and d the general arithmetic sequence formula

General formula:

We have  and d = -7

So the formula to find the nth term would be

Answer:

a_n=-8+(n-1)-7

Step-by-step explanation:

General arithmetic sequence formula: a_n=a_1+(n-1)d

where a_1 = first term, and d = common difference.

The first term is -8

And the common difference appears to be - 7 as 7 is subtracted to get to the next term. Ex. -8 - 7 = -15, -15 - 7 = - 22 and so on.

To get the explicit formula of the sequence we simply plug in the values of a1 and d the general arithmetic sequence formula

General formula: a_n=a_1+(n-1)d

We have a_1=-8 and d = -7

So the formula to find the nth term would be

a_n=-8+(n-1)-7

What is the slope of the line that goes through the points (7,10) and (3,-3)
PilotLPTM [1.2K]
Ypu would subtract Y from the other points Y
- 3 - 10 =  - 13
Then you would subtract X from the ither points X.
3 - 7 =  - 4
Then you would put the Y value over the X
\frac{ - 13}{ - 4}
Then simiplify
\frac{13}{4}

PLEASEEE HURRYYY
Masteriza [31]

Answer:

(2,-5) and (2,1).

Step-by-step explanation:

We need to find the find all the points having an x coordinate of 2 whose distance from the point (-2,-4) is 5.

A circle with center (-2,-4) and radius 5 represents all the points whose distance from the point (-2,-4) is 5.

Standard form of a circle is

(x-h)^2+(y-k)^2=r^2

where, (h,k) is center and r is the radius.

(x-(-2))^2+(y-(-4))^2=(5)^2

(x+2)^2+(y+2)^2=25

Now, put x=2.

(2+2)^2+(y+2)^2=25

(4)^2+(y+2)^2=25

(y+2)^2=25-16

(y+2)^2=9

Taking square root on both sides.

y+2=\pm\sqrt{9}

y+2=\pm3

y+2=-3\text{ or }y+2=3

y=-5\text{ or }y=1

So, the y-coordinates of the points are -5 and 1.

Therefore, the required points are (2,-5) and (2,1).
