How can you determine the best method of solving a system of equations?

Elimination is best used when both equations are in standard form (Ax + By = C).

Elimination is also the best method to use if all of the variables have a coefficient other than 1.

Hope this helps

Line q passes through the point (4,6)and (0,6).

larisa86 [58]

Answer:

The equation of the line passing through the points (4, 6) and (0, 6) will be:

y = 6

The graph of the equation y = 6 is also attached.

Step-by-step explanation:

The slope-intercept form of the line equation

$y = mx+b$

where

m is the slope

b is the y-intercept

Given the points

(4, 6)

(0, 6)

Finding the slope between (4, 6)and (0, 6).

Using the formula

Slope = m = [y₂ - y₁] / [x₂ - x₁]

= [6 - 6] / [0 - 4]

= 0 / -4

= 0

Thus, the slope of the line = m = 0

The slope m = 0 means the line is horizontal. Because the slope of the horizontal line is 0.

As the y-values are not changing with respect to the x-values.

Therefore,

The equation of the line passing through the points (4, 6) and (0, 6) will be:

y = 6

The graph of the equation y = 6 is also attached.

Evaluate the surface integraliintegral.gifSF � dSfor the given vector field F and the oriented surface S. In other words, find t

ehidna [41]

Looks like the paraboloid has equation

$z=2-x^2-y^2$

and $S$ is the part of this surface with $0\le x\le1$ and $0\le y\le1$ . Parameterize $S$ by

$\vec s(u,v)=u\,\vec\imath+v\,\vec\jmath+(2-u^2-v^2)\,\vec k$

with $0\le u\le1$ and $0\le v\le1$ . Take the normal vector to $S$ to be

$\vec s_u\times\vec s_v=2u\,\vec\imath+2v\,\vec\jmath+\vec k$

Then the flux of $\vec F$ across $S$ is

$\displaystyle\iint_S\vec F\cdot\mathrm d\vec S$

$\displaystyle=\int_0^1\int_0^1(uv\,\vec\imath+v(2-u^2-v^2)\,\vec\jmath+u(2-u^2-v^2)\,\vec k)\cdot(2u\,\vec\imath+2v\,\vec\jmath+\vec k)\,\mathrm du\,\mathrm dv$

$\displaystyle=\int_0^1\int_0^1(2u^2v+(2v+1)u(2-u^2-v^2))\,\mathrm du\,\mathrm dv=\boxed{\frac{293}{180}}$
