1+4x=-5+7x what does x equal<br>

katrin [286]

Answer:

x = 2

Step-by-step explanation:

Given

1 + 4x = - 5 + 7x ( subtract 7x from both sides )

1 - 3x = - 5 ( subtract 1 from both sides )

- 3x = - 6 ( divide both sides by - 3 )

x = 2

brainliest?? Which transformation or sequence of transformations would produce an image that is not congruent to its pre‐image?

antoniya [11.8K]

Answer:

Brainliest!!!

Step-by-step explanation:

options:

A. A translation of 3 units to the left followed by a reflection across the x-axis

B. A rotation of 90 clockwise followed by a translation of 6 units to the left

C. A translation of 5 units to the left followed by a dilation of a factor of 2

D. A reflection across the y-axis followed by a rotation of 180 counterclockwise

All the other options deal with transformatios that just move the figure without modifying their dimmenssions.

When you dilate a figure you increase the dimmenssions, so the result is a different figure.

the answer is C

Calculate the integral s f · ds, where s is the entire surface of the solid half ball x2 + y2 + z2 ≤ 1, z ≥ 0, and f = (x + 3y5)

SSSSS [86.1K]

The divergence theorem applies since $\mathcal S$ is a closed surface. We have

$\displaystyle\iint_{\mathcal S}\mathbf f(x,y,z)\cdot\mathrm d\mathbf S=\iiint_{\mathcal V}\nabla\times\mathbf f(x,y,z)\,\mathrm dV$

where $\mathcal V$ is the space enclosed by the surface $\mathcal S$ . The divergence of the given vector field is

$\nabla\times\mathbf f(x,y,z)=\dfrac{\partial(x+3y^5)}{\partial x}+\dfrac{\partial(y+10xz)}{\partial y}+\dfrac{\partial(z-xy)}{\partial z}=1+1+1=3$

So we can write the volume integral (in spherical coordinates) as

$\displaystyle3\iiint_{\mathcal V}\,\mathrm dV=3\int_{\varphi=0}^{\varphi=\pi/2}\int_{\theta=0}^{\theta=2\pi}\int_{\rho=0}^{\rho=1}\rho^2\sin\varphi\,\mathrm d\rho\,\mathrm d\theta\,\mathrm d\varphi=\frac{4\pi}3$
