Which equation hasd a graph parallel to the graph of 9x+3y=-22

tatyana61 [14]

Answer:

b - any real number

Step-by-step explanation:

Parallel lines have the same slope.

We have the equation of a line in the standard form Ax + By = C.

Convert to the slope-intercept form y = mx + b

m - slope

b - y-intercept

$9x+3y=-22$ subtract 9x from both sides

$3y=-9x-22$ divide both sides by 3

$y=-3x-\dfrac{22}{3}$

Therefore we have the slope m = -3.

Put it to the equation of a line:

$y=-3x+b$ add 3 to both sides

$3x+y=b$

Answer: OPTION B

Step-by-step explanation:

Let's call:

c: the number of cars.

m: the number of motorcycles.

Based on the given information, you can set up the following system of equations:

$\left \{ {{c+m=38} \atop {4c+2m=104}} \right.$

You can solve it by the Elimination method:

- Multiply the first equation by -4.

- Add both equations to cancel out the variable "c".

- Solve for "m":

$\left \{ {(-4)(c+m)=38(-4)} \atop {4c+2m=104}} \right.\\\\\left \{ {-4c-4m=-152} \atop {4c+2m=104}} \right.\\-------\\-2m=-48\\m=24$

(24 motorcycles)

- Substitute m=24 into any of the original equations ans solve for "c". Then:

$c+24=38\\c=38-24\\c=14$

(14 cars)

Find the surface area of that is part of the plane and that lies inside the elliptic cylinder? Plane: 10x+3y+z=10 Cylinder: (x^2

krek1111 [17]

Parameterize the surface of interest $S$ by $\mathbf x(u,v)=\langle9u\cos v,10u\sin v,10-90u\cos v-30u\sin v\rangle$ with $u\in[0,1]$ and $v\in[0,2\pi]$ .

Then the area is given by the surface integral
$\displaystyle\iint_S\mathrm dA=\int_0^1\int_0^{2\pi}\left\|\frac{\partial\mathbf x}{\partial u}\times\frac{\partial\mathbf x}{\partial v}\right\|\,\mathrm dv\,\mathrm du=90\sqrt{110}\pi$
