Answer:

x=12

Step-by-step explanation:

LM + MN = LN

2x-16 + x-9 = 11

Combine like terms

3x-25=11

Add 25 to each side

3x-25+25 = 11+25

3x = 36

Divide by 3

3x/3=36/3

x = 12

Please helpppp !!! Write this in y=Mx+b form

emmasim [6.3K]

Answer:

y =(-3/2)x

Step-by-step explanation:

(0,0) ; (2 , -3)

Slope = $\frac{y_{2}-y_{1}}{x_{2}-x_{1}}$

$= \frac{-3-0}{2-0}\\\\= \frac{-3}{2}$

Equation: y - y1 =m(x-x1)

y - 0 = $\frac{-3}{2}(x- 0)\\$

$y = \frac{-3}{2}x$

Find the area of the surface. the part of the surface y = 5x + z2 that lies between the planes x = 0, x = 1, z = 0, and z = 1.

Alex787 [66]

Parameterize the part of the surface we care about, denoted $\mathcal S$ , by

$\mathbf r(u,v)=\langle u,5u+v^2,v\rangle$

with $0\le u\le1$ and $0\le v\le1$ .

Then

$\|\mathbf r_u\times\mathbf r_v\|=\|\langle5,-1,2v\rangle\|=\sqrt{4v^2+26}$

The area is given by the surface integral

$\displaystyle\iint_{\mathcal S}\mathrm dS=\int_{v=0}^{v=1}\int_{u=0}^{u=1}\|\mathbf r_u\times\mathbf r_v\|\,\mathrm du\,\mathrm dv$

$=\displaystyle\int_{v=0}^{v=1}\sqrt{4v^2+26}\,\mathrm dv=\sqrt{\dfrac{15}2}+\dfrac{13}2\sinh^{-1}\sqrt{\dfrac2{13}}$

Find the Equation of the line

romanna [79]

Answer:

$y = \frac{1}{2}x + \frac{1}{2}$

Step-by-step explanation:

Mark any two point on the line

(-1 , 0) & (-3 , -1)

Slope = $\frac{y_{2}-y_{1}}{x_{2}-x_{1}}\\$

$= \frac{-1-0}{-3-[-1]}\\\\= \frac{-1}{-3+1}\\\\= \frac{-1}{-2}\\\\= \frac{1}{2}$

m = 1/2 ; (-1 , 0)

Equation: $y - y_{1} =m(x -x_{1})$

$y - 0 = \frac{1}{2}(x - [-1])\\\\y = \frac{1}{2}(x + 1)\\\\y = \frac{1}{2}x + \frac{1}{2}$

If you have a rectangle with the width of 6 in and a length of 10 in. And you want to create a scaled copy using a scale factor

snow_tiger [21]

Answer:

The new side lengths will be 24 inches and 40 inches

Step-by-step explanation:

Here, given the width and length of a rectangle and we want to create a scaled copy using a scale factor of 4, we want to know the new side lengths

What we simply want to do here is to scale up or dilate the side lengths of the rectangle using a scale factor of 4

Hence, the new side lengths will be (4 * 6) inches and (10 * 4) inches

The new side lengths will be 24 inches and 40 inches
