How to solve linear equations

Harman [31]

There are many methods to solve linear equations, such as:

1. Equating method: Let's take two simultaneous linear equations x+y=5 and x-y=1.

x+ y=5 can be written as x = 5-y.........(1)

In the same way,

x-y=1 or, x = 1+y.............(2)

Here, we equate the two equations and get the value of unknowns.

2. Substituting method: Again, take the equations x+y=5 and x-y=1.

x+y=5

or, x=5-y.........(1)

x-y=1............(2)

Substituting equation (1) in (2),

(5-y) - y=1

or, 5-2 y = 1

or, y = 2.

This is called substitution method.

3. Formula method: simultaneous linear equations can also be solved by formula.

If there are two equations: ax+by +c=0 and d x+e y+f=0 then the solution of such equation would be:

x = (bf - e c)/( a e - db), y = (a f-dc)/(db - a e).

For example,

2 x+ 3 y = 10 or, 2 x +3 y-10=0..................(1)

x+y=-44 or, x+y+44=0..................(2)

Comparing equation (1) and (2) with ax+by+c = 0 and dx+ey+f=0, a=2, b=3, c=-10, d =1, e=1, f=44.

Using formula,

x= -142 and y = 98.

The total operating cost to run the organic strawberry farm varies directly with its number of acres. What is the constant of va

kow [346]

Answer:

$16\ acres$

Step-by-step explanation:

we know that

A relationship between two variables, x, and y, represent a proportional variation if it can be expressed in the form $k=\frac{y}{x}$ or $y=kx$

In a proportional relationship the constant of proportionality k is equal to the slope m of the line and the line passes through the origin

Let

x ----> the number of acres

y ---> total operating costs

we have the ordered pair (20,551,520)

For x=20 acres, y=$551,520

Find the value of the constant of proportionality k

$k=\frac{y}{x}$

substitute the values of x and y

$k=\frac{551,520}{20}=\$27,576\ per\ acre$

The linear equation is equal to

$y=27,576x$

Find out how many acres are on a farm with a total operating cost of $441,216

For y=$441,216

substitute in the linear equation the value of y and solve for x

$441,216=27,576x$

$x=441,216/27,576$

$x=16\ acres$

The nth term of a sequence is 20-n^2

Nimfa-mama [501]

Answer:

a) 20 - 3^2 = 11

b) 5th, 20 - 5^2 = -5

Step-by-step explanation:

The answer assumes your terms begin at 1. If the terms begin at zero

a) 16

b) 6th term

if you chose to be extremely technical you would take the square root of 20.1 or 20.00000009 but I'm assuming they want whole numbers
