-3y+5x=26,-2y-5x=-16

Mathematics

ch4aika [34]3 years ago

Answer:

x=4

y=-2

Step-by-step explanation:

We are give two linear equations and asked to solve them. The two equations are

-3y+5x=26

-2y-5x=-16

Adding both equations

-5y=10

Dividing both sides by -5

y=-2

Substitute y=-2 in first equation

-3(-2)+5x=26

6+5x=26

5x=20

Dividing both sides by 5

x=4

8TH GRADE MATH ¯\_(ツ)_/¯
Nonamiya [84]

If <em>n</em> = 0.151515…, then 100<em>n</em> = 15.151515…

Then

100<em>n</em> - <em>n</em> = 15.151515… - 0.151515…

99<em>n</em> = 15

<em>n</em> = 15/99 = 5/33

Find an explicit formula for the geometric sequence -40,-20,-10......
garik1379 [7]

Answer:

The explicit formula for the geometric sequence is c(n) = -40\cdot \left(\frac{1}{2} \right)^{n-1}.

Step-by-step explanation:

By definition of geometric sequence, we should use the following expression:

c(n) = c_{1}\cdot r^{n-1}, n \ge 1 (1)

Where:

c_{1} - First term.

r - Geometric rate.

n - Position of the element within the series.

If we know that c_{1} = -40 and r = \frac{1}{2}, then the explicit formula for the geometric sequence is:

c(n) = -40\cdot \left(\frac{1}{2} \right)^{n-1}

The explicit formula for the geometric sequence is c(n) = -40\cdot \left(\frac{1}{2} \right)^{n-1}.
