This is the answer...
y=250-25x
y=30+30x
Let
. The tangent plane to the surface at (0, 0, 8) is

The gradient is

so the tangent plane's equation is

The normal vector to the plane at (0, 0, 8) is the same as the gradient of the surface at this point, (1, 1, 1). We can get all points along the line containing this vector by scaling the vector by
, then ensure it passes through (0, 0, 8) by translating the line so that it does. Then the line has parametric equation

or
,
, and
.
(See the attached plot; the given surface is orange, (0, 0, 8) is the black point, the tangent plane is blue, and the red line is the normal at this point)
Answer:
the third one
Step-by-step explanation:
add 2y and 16 to both sides. then divide by 2
Answer:
A
Step-by-step explanation:
Every input (x value) can have only ONE ouput (y value) to be a function, y- values can be repeated but x- values cannot
