That's a progression, for each step you increase the total next number by 8+6.

So
1. 3+8=11
2. 11+8+6=25
3. 25+8+6+6=45
4. 45+8+6+6+6=71
5. 71+8+6+6+6+6=103
6.103+8+6+6+6+6+6=141
7.141+8+6+6+6+6+6+6=185
8.185+8+6+6+6+6+6+6+6=235
9.235+8+6+6+6+6+6+6+6+6=291

What is meant by green mathematics?

ad-work [718]

The green mathematics tells about the impulse response of an in homogeneous linear differential operator.

According to the statement

we have to explain the green mathematics.

In mathematics, Actually there is a Green Function which was founded by a mathematician George Green.

In this function, a Green's function is the impulse response of an in homogeneous linear differential operator defined on a domain with specified initial conditions or boundary conditions.

The example of green function is the Green's function G is the solution of the equation LG = δ, where δ is Dirac's delta function; the solution of the initial-value problem Ly = f is the convolution (G ⁎ f), where G is the Green's function.

Actually in this function, it gives the relationship between the line integral of two dimensional vector over a closed path by a integral.

In this there is a green theorem, which relates a line integral around a simply closed plane curve C and a double integral over the region enclosed by C.

So, The green mathematics tells about the impulse response of an in homogeneous linear differential operator.

Solve this system using substitution then write your answer as an ordered pair (x,y) X-5y=4 and Y=2x+14

Nikolay [14]

Answer:

(74/9,274/9)

Step-by-step explanation:

You have

x-5y=4 and

y=2x+14

so we subsitute y in the first equation

x-5(2x+14)=4

x-10x-70=4

-9x=74

x=74/9

so y=2(74/9)+14

y=148/9+14

y=274/9

so the oredered pair is

(74/9,274/9)
