Answer:
(a + c, b)
Step-by-step explanation:
First the easy part... the Y-value.
There's an horizontal line where the P is... that line has a point identified (a,b). So, the Y-value of P is b.
Now the X-value.
You see that P is a bit right to c, so it's something more than c, but how much? If you look, P is as right to C as a is to the origin. Since we know it's a parallelogram, the line that goes from origin to (a,b) is parallel to the one going from C to P.
So the X-value of point P is: c + a
Answer:
The derivative is
Step-by-step explanation:
The function is given by
Differentiate with respect to x, we get
12 - x = 20 - 5x
You see that -x and -5x both have an 'x' variable? This means they are 'like' terms. To get -x to the other side, we must add (if like terms are on opposite sides, do the opposite of what the sign says, e.g. - will be +)
12 = 20 - 4x
Now move 20 to the other side. Remember, do the opposite! Since 20 is positive, we must minus 20 to the other side.
-8 = -4x
To get x by itself, you will need to get rid of the coefficient of -4. -4x basically means -4 times x, so the opposite of that would be divide! Divide by -4
2 = x (Since both sides have a negative, they cancel out to give a positive)
x = 2
