Answer:
ok the rest
Step-by-step explanation:
F ( x) = y = ( x - 4 ) / ( 33 - x )
( 33 - x ) * y = x - 4
33 y - x y = x - 4
- x y - x = - 33 y - 4 / * ( - 1 )
( we shall multiply both sides of an equation by - 1 )
x y + x = 33 y + 4
x ( y + 1 ) = 33 y + 4
x = ( 33 y + 4 ) / ( y + 1 )
Answer:
The inverse function is:
Given a scalar number
and a vector
v, the product between
and
v is a vector, with
- magnitude given by the product between the absolute value of
and the magnitude of
v- direction given by the sign of
: if a is positive, the final vector has same direction of
v; if a is negative, the final vector has opposite direction to
v.
In our problem, the scalar number is
. This means that the product between the vector and this number:
- has magnitude equal to
times the magnitude of the vector
- has opposite direction with respect to the original vector (because the scalar
is negative)
Therefore, the correct answer is
<span>B.) The vector will change direction and decrease in magnitude.</span>
