What is the salon to the equation? 15 = |x| - 5

earnstyle [38]

Step-by-step explanation:

15 = |x| - 5

|x| - 5 = 15

|x| = 15 + 5

|x| = 20

x = ±20

x = -20 or 20

Option → B

What is the equation of the line that passes through the point (-6, 4) and has a<br> slope of -5/6

tangare [24]

Answer:

$y = -\frac{5}{6}x -1$

Step-by-step explanation:

So, we know the slope is -5/6. From here we can write this equation:

$y = -\frac{5}{6}x + b$

In the question they give us both the x and y in this equation (-6,4)

Plug them in to the equation and solve for b:

$4 = -\frac{5}{6} (-6) + b\\4 = \frac{30}{6} + b\\4 = 5 + b \\-1 = b$

Now, we can write the equation as follows:

$y = -\frac{5}{6}x -1$

<em>I hope this helps!!</em>

(a) Find parametric equations for the line through (1, 3, 8) that is perpendicular to the plane x − y + 4z = 3. (Use the paramet

tigry1 [53]

Answer:

a) x = 1 + t

y = 3 - t

z = 8 +2t

b) In XY plane (-3,-1,0)

In YZ plane (0, 4, 6)

In XZ plane ( 4,0,14)

Step-by-step explanation:

The equation of plane is given as

x -y +2z = 5

COMPARE THE ABOVE EQUATION with Ax+ By +Cz = d

A = 1, B = -1. C = 2

N = (1,3,8) {GIVEN POINT]

the parametric eqn. of line P(Xo , Yo, Zo) and prependicular plan Ax+ By+ Cz = d is given as

X = Xo+ At

Y = Yo + Bt

Z=Zo + Ct

x = 1 + t

y = 3 - t

z = 8 +2t

b) Line intersecting XY plane if z equal to zero i.e

0 = 8 + 2t

t =-4

for t = -4

x = -3, y = -1, z = 0

In YZ plane, x = 0

t = -1

interesting point will be

(0, 4, 6)

In XZ plane, Y = 0

t = 3

interesting point will be

(4, 0, 14)

Andrew [12]

The volume of the cylinder with height 6 meters and the radius 18 meters is $6,104.16 m^{3}$ .

<h3>What is a volume of a cylinder?</h3>

The volume of a cylinder is the capacity of the cylinder which calculates the amount of material quantity it can hold.

Given that, the height of a cylinder=6 meters and the diameter of a cylinder=6×6=36 meters (A diameter that is 6 times the measure of the height)

Now, radius $(r)=\frac{d}{2} =18 meters$
