\\ \sf\longmapsto \dfrac{2}{3}+f=\dfrac{1}{5}

\\ \sf\longmapsto f=\dfrac{1}{5}-\dfrac{2}{3}

\\ \sf\longmapsto f=\dfrac{3-10}{15}

\\ \sf\longmapsto f=\dfrac{-7}{15}

Answer:

D. -7/15

Step-by-step explanation:

Step 1: Simplify both sides of the equation.

f+ 2/3-2/3= 1/5-2/3

Step 2: Subtract 2/3 from both sides.

f= -7/15

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.

Which equation represents the line that has a slope of 4 and passes through the point (2, 7)?​
Wittaler [7]

Answer:

The answer is y = 4x - 1.

Step-by-step explanation:

☆The equation we'll be using: y = mx + b

☆Since we already have the slope. we have to find the y-intercept.

☆y = mx + b \\  \\ 7 = 4(2) + b \\  7 = 8 + b \\  \frac{ - 8 =  - 8 \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \: }{ - 1 = b \:  \:  \:  \:  \:  \:  \:  \:  \:  \: }

☆Using the information we gathered and was given, we just to put them together.

☆y = 4x - 1

Horatio is solving the equation -3/4+2/5x=7/20x-1/2. Which equations represent possible ways to begin solving for x? Check all t
trapecia [35]

Answer:

  • 2/5x=7/20x+1/4
  • -3/4=-1/20x-1/2
  • -3/4+1/20x=-1/2

Step-by-step explanation:

If you add 3/4 to both sides of the equation, you get ...

... 2/5x = 7/20x + 1/4 . . . . first choice

If you subtract 2/5x from both sides of the equation, you get ...

... -3/4 = -1/20x -1/2 . . . . third choice

If you subtract 7/20x from both sides of the equation, you get ...

... -3/4 +1/20x = -1/2 . . . . last choice

Choices 2 and 4 are erroneous versions of choices 1 and 3, so do not apply.
