$8-x=2x-1\ \ \ \ |-8\\\\-x=2x-9\ \ \ |-2x\\\\-3x=-9\ \ \ \ |:(-3)\\\\\boxed{x=3}$

1) subtract 8 from both sides

2) subtract 2x from both sides

3) divide both sides by (-3)

Find a parametrization of the line in which the planes x + y + z = -6 and y + z = -8 intersect.

rewona [7]

Answer:

L(x,y) = (2,-8,0) + (0,-1,1)*t

Step-by-step explanation:

for the planes

x + y + z = -6 and y + z = -8

the intersection can be found subtracting the equation of the planes

x + y + z - ( y + z ) = -6 - (-8)

x= 2

therefore

x=2

z=z

y= -8 - z

using z as parameter t and the point (2,-8,0) as reference point , then

x= 2

y= -8 - t

z= 0 + t

another way of writing it is

L(x,y) = (2,-8,0) + (0,-1,1)*t

Solve for g gg. Give an exact answer. 10 ( 0.4 + 0.5 g ) = 4 g 10(0.4+0.5g)=4g10, left parenthesis, 0, point, 4, plus, 0, point,

kirill115 [55]

Answer:

the value of g is -4

Step-by-step explanation:

$10 ( 0.4 + 0.5 g ) = 4 g$

Our aim is to solve for g

multiply 10 inside the parenthesis

$4+5g = 4g$

Now combine like terms

Subtract 5g from both sides

$4+5g-5g= 4g-5g$

$4=-g$

Divide both sides by -1

$g=-4$
