How do you solve the equation x-2y-1=0 y-5x+14=0

Mathematics
1 answer:
Tcecarenko [31]3 years ago

The solution is x= 3 and y = 1

Step-by-step explanation:

Given equations are:

x-2y-1 = 0\ \ \ \ Eqn1\\y-5x+14 = 0\ \ \ \ Eqn2

From equation 1:

x = 2y+1

Putting in equation 2:

y - 5(2y+1)+14 = 0\\y-10y-5 +14 = 0\\-9y-5+14 = 0\\-9y+9 = 0\\-9y+9-9 = 0-9\\-9y = -9

Dividing both sides by -9

\frac{-9y}{-9} = \frac{-9}{-9}\\y = 1

Putting y = 1 in equation 1:

x - 2(1)-1 = 0\\x -2-1 = \\x-3 = 0\\x-3+3 = 0+3\\x = 3

Hence,

The solution is x= 3 and y = 1

Consider the arithmetic sequence 10,12,14,16 if n is an integer, which of these functions generate the sequence?
BaLLatris [955]

Given:

The arithmetic sequence is:

10, 12, 14, 16, ...

To find:

The function that generates the given sequence if n is an integer.

Solution:

We have,

10, 12, 14, 16, ...

Here, the first term is 10 and the common difference is:

d=a_2-a_1

d=12-10

d=2

The nth term of an arithmetic sequence is:

a_n=a+(n-1)d

Where, a is the first term, d is the common difference and n\geq 1.

Putting a=10,d=2 in the above formula, we get

a_n=10+(n-1)2

a_n=10+2n-2

a_n=8+2n

Therefore, the function a_n=8+2n, n\geq 1 generates the sequence.
