) find a vector parallel to the line of intersection of the planes 5x − y − 6z = 0 and x + y + z = 1.
snow_tiger [21]
The cross product of the normal vectors of two planes result in a vector parallel to the line of intersection of the two planes.

Corresponding normal vectors of the planes are
<5,-1,-6> and <1,1,1>

We calculate the cross product as a determinant of (i,j,k) and the normal products

    i   j   k
   5 -1 -6
   1  1  1

=(-1*1-(-6)*1)i -(5*1-(-6)1)j+(5*1-(-1*1))k
=5i-11j+6k
=<5,-11,6>

Check orthogonality with normal vectors using scalar products
(should equal zero if orthogonal)
<5,-11,6>.<5,-1,-6>=25+11-36=0
<5,-11,6>.<1,1,1>=5-11+6=0

Therefore <5,-11,6> is a vector parallel to the line of intersection of the two given planes.

Charlie was carrying around the steps to solve Square root of 6x plus 4 = 8. On his way through the Math Factory, Charlie droppe
fomenos

Answer: Order will be F,D,C and Fourth Option is correct and  x = 10

Step-by-step explanation:

Since we have given that

\sqrt{6x+4}=8

We first transpose the square root to the right , so it becomes square of 8,i.e.

6x+4=8^2\\\\6x+4=64

Now, transpose 4 to the right so it will get subtract from 64 i.e.

6x=64-4\\\\6x=60

Since 6 is multiplied to x on tranposing it will get divided by 60 i.e.

x=\frac{60}{6}\\\\x=10

Hence, on simplification, we get x=10.

Hence , the order is F,D,C.
