Find the valid value(s) for x:<br> x2 +5x+6<br> = 1<br> x+3

-BARSIC- [3]

Answer:

x=-1

Step-by-step explanation:

x+3≠0

x≠-3

x²+5x+6=x+3

x²+5x+6-x-3=0

x²+4x+3=0

x²+x+3x+3=0

x(x+1)+3(x+1)=0

(x+1)(x+3)=0

x+3≠ 0

so x+1=0

x=-1

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

In a circle, what does the ratio A/r^2 represent?

Pepsi [2]

The ratio A/r² would represent $\pi$ which is the circumference of a circle divided by its diameter.

You can see this because the area of a circle is $\pi$ r² and if you divided that by the radius squared, you are given pi which is the circumference of a circle divided by its diameter.
