Since 4 is right outside the (5 - x), you need to distribute the 4. so, you do 4 • 5 (20) and 4 • -x (-4x) which ends up as 20 -4x = 32.

then you solve!
you subtract the 20 on the left side so you are only left with the -4x. since you subtracted the 20 in the left side, you have to do the same in the right. so, 32-20 is 12.

then, you are left with -4x = 12. to get the variable, x, alone, you have to divide it by -4. but, if you do this in the left, you HAVE to do it on the right too!

so, 12 divided by -4 is equal to -3.

this means x is equal to -3!!

Find the distance between the pair points (-2, -3) and (-12,-19)

mojhsa [17]

D = √(y2-y1)² + (x2-x1)²

d = √(-3+19)² + (-2+12)²

d = √16² + 10²

d = √256 + 100
d = √356
d = 18.87 units

In short, Your Answer would be: 18.87 units

Hope this helps!

Which answer describes the type of sequence? 200, 40, 8, 1.6, ...

GalinKa [24]

Answer:

Option 1 the given sequence is a geometric.

Step-by-step explanation:

We have been given with the series

$200,40,8,1.6$

Arithmetic sequence is the sequence in which difference between consecutive terms is same that is common difference d

$d=a_2-a_1$

$d=40-200=-160$ here $a_2=40,a_1=200$

$d=8-40=-32$ here $a_2=8,a_1=40$

We can see the difference is not same

Hence, the given sequence is not arithmetic sequence.

Geometric sequence is the sequence in which ratio of consecutive terms is same that is common ratio r

$r=\frac{a_2}{a_1}$

$r=\frac{40}{200}=\frac{1}{5}$ here $a_2=40,a_1=200$

$r=\frac{8}{40}=\frac{1}{5}$ here $a_2=8,a_1=40$

$r=\frac{1.6}{8}=\frac{1}{5}$ here $a_2=1.6,a_1=8$

We can see the ratio is same.

Hence, given sequence is geometric

Therefore, Option 1 is correct given sequence is geometric.

The distance between two points is 6_/6.One endpoint is (4,-1). It is known that the y-coordinate of the other endpoint is 9.

babunello [35]

The x-coordinate of the given endpoint will be " $x = 4 \pm 2\sqrt{29}$ ".

According to the question,

The end points are:

$(x_1,y_1) = (4,-1)$
$(x_2, y_2) = (x,9)$

Distance,

$6\sqrt{6}$

As we know,

The distance formula,

→ $Distance = \sqrt{(x_2-x_1)^2+(y_2-y_1)^2}$

By substituting the values, we get

→ $6\sqrt{6} = \sqrt{(x-4)^2+(9+1)^2}$

→ $216= (x-4)^2+100$

→ $(x-4)^2 = 116$

→ $x-4 = \pm \sqrt{116}$

→ $x-4=\pm 2\sqrt{29}$

→ $x = 4 \pm 2\sqrt{29}$

Thus the above answer is right.
