The first derivative f'(x) gives the instantaneous slope of f(x). If f'(x) is positive, then f(x) is increasing (positive slope), and if f'(x) is negative, then f(x) is decreasing (negative slope). If f'(x) = 0, then the graph of f(x) is flat at the point (slope = 0).

It is: (x-y)4

The coordinates of every one of the infinitely many points on the line defined by the equation is a solution.

The value of X in the equation 2x-1-6 5 plus 6x is -3.

No matter how many times you multiply zero by itself, you will always get zero.

They are: x = -2 and y = -1.

2x2 + 11x + 12 = 2x2 + 3x + 8x + 12 = x*(2x + 3) + 4*(2x + 3) = (2x + 3)*(x + 4)

There appear to be two equations, but no ordered pair.

2x + 7b is an expression. Since it is not an equation it cannot be solved. Furthermore, as an expression, there is no meaninful simplification, either.

We're given:

9x + 2x = 121

The first step is to group like terms on the left:

(9 + 2)x = 121

11x = 121

Now divide both sides by 11:

11x/11 = 121/11

x = 11

Multiply the cross products, and see if they are equal. If they are equal, the proportion is true. If they are unequal, the proportion is false.

x2 +2x+2=0 cannot be factored.
If we look at b2 -4ac which is the
we see it is 4-4(2)=4-8 which is negative.
This means there two roots and they are not real.

The quadratic equation tells us the solution (-2+ 2i)/2 and (-2-2i)/2
or -1+i and -1-i.

Yes.

0 = 12 is neither. It is a false statement.

x2-x3+2x = 0

x(-x2+x+2) = 0

x(-x+2)(x+1) = 0

Points of intersection are: (0, 2), (2,10) and (-1, 1)

As long as time permits you defiantly should.

4X - 32 + 5X + 50 = 180

gather like terms on the left

9X + 18 = 180

subtract 18 from each side

9X = 162

divide both sides by 9

X = 18

check

4(18) - 32 + 5(18) + 50 = 180

72 - 32 + 90 + 50 = 180

40 + 90 + 50 = 180

180 = 180
