Hi friend,
Answer of 4th u need nah as u ticked on it-:
Yes then-:
8*x*x*y*z*z*z*z/16*x*y*y*z
=x*z^3/2y
Hope it helps..........
3x+2=x+2x+4
-2 -2
3x=x+2x+4-2
3x=3x+4-2
-3x -3x
x= 4-2
x=2
Answer:

Step-by-step explanation:
By definition, a relation is a function if and only if each input value have one and only one output value.
The input values are the x-values and the output values are the y-values.
Given the function f(x):

You need to substitute
into this function:

And now you must evaluate in order to find the corresponding output value.
You get:

The function g(x) is:

Then, you need to substitute
in the function:

And finally you must evaluate in order to find the corresponding output value. This is:

Answer:a

Answer:
- A = (0, 1)
- B = (3, -2)
- area = 4.5 square units
Step-by-step explanation:
Rewriting the equations to make x the subject, we have ...
x = y² -1 . . . . . [eq1]
x = 1 - y . . . . . .[eq2]
At the points of intersection, the difference will be zero.
y² -1 -(1 -y) = 0
y² +y -2 = 0
(y -1)(y +2) = 0
The y-coordinates of points A and B are 1 and -2.
The corresponding x-coordinates are ...
x = 1 -{1, -2} = {1 -1, 1+2} = {0, 3}
Then A = (0, 1) and B = (3, -2).

A differential of area can be written ...
(x2 -x1)dy = ((1 -y) -(y² -1))dy = (2 -y -y²)dy
Integrating this over the interval y = [-2, 1] gives the area.

The area of the shaded region is 4.5 square units.
