Calculus

the sum of -5 and 3x

2x + 5 = -76 - 7x

Add 7x to both sides: 9x + 5 = - 76

Subtract 5 from both sides: 9x = -81

Divide both sides by 9: x = -81/9 = -9

In 7x+7, x is a variable.

That system of equations has no solution. When the two equations are graphed,

they turn out to be the same straight line, so there's no such thing as a single

point where the two lines intersect. There are an infinite number of points that

satisfy both equations.

2x-3 = 21+10x

2x-10x = 21+3

-8x = 24

x = -3

i know you add x to x and y to y but not x to y or y to x

so i answer the exponents and get 334y over 225y times 13824x

324y

----------------

225y 13824x

so i think that you would have to divide 324y by 225y and get 1.44

so if i am right you get

1.44 y 13824 x

252 inches

As long as you have your lettering correct then

That would be a very simple graph, in the form of a straight line. The line passes through the origin, that is, the intersection of the x and y axes, since as you see from the defining equation y = 3x, when x is zero, y is also zero (3x0 = 0). To draw the line we need only one other point. Let look at x = 4. So, y = 3x4 = 12. We mark a dot at (4,12) and then connect that dot to the origin and voila, we have the graph. The line can be extended as far as you like, of course, it doesn't run only from x=0 to x=4. Lines continue forever.

The question is not quite clear, do you mean -6x+3y = -18 and -10+5y = -30?

If so then the solution is:

-10+5y= -30

5y = -30+10

5y = -20

y = -4

Substitute the value of y into the equation -6x+3y = -18:

Answer: x = 1 and y = -4

(X-3)(X-3)

Foil that and you will see tha X = 3. This is a parabola that touches the X axis at X = 3.

The answer is 4. 3x4 - 1 =11

12 - 1 = 11

You can divide the integers in this case - 4 divided by 2 and 9 divided by 3. You would get 2 over x plus 3 over x.

4/2x + 9/3x = 2/x + 3/x = 5/x

x = +1 or -1

x2-18x+81 = (x-9)(x-9) when factored

-9-7x=-5

express first the equation in terms of x,

where,

7x=-9+5

then,

7x=-4

thus,

x=-4/7

If: y = 4x^2 -12x -3 and y = x^2 +11x+5

Then: 4x^2 -12x -3 = x^2 +11x+5

Transposing terms: 3x^2 -23x -8 = 0

Dividing all terms by 3: x^2 -23/3x -8/3 = 0

Completing the square: (x-23/6)^2 = 625/36

Square root both sides: x-23/6 = -25/6 or 25/6

Add 23/6 to both sides: x = -1/3 or 8

Therefore the values of x are: -1/3 or 8

x3 + 2x2 - 5x - 6 = x3 + x2 + x2 + x - 6x - 6 = x2(x + 1) + x(x + 1) - 6(x + 1)

= (x + 1)(x2 + x - 6) = (x + 1)(x2 + 3x - 2x - 6) = (x + 1)[x(x + 3) - 2(x + 3)]

= (x + 1)(x + 3)(x - 2)

It might have been possible to answer the question had you given some information about "this function". However, since you have not bothered to share that crucial bit of information, I cannot provide a more useful answer.

5x + 33 = 15x - 77

Subtract 5 x from both sides: 33 = 10x - 77

Add 77 to both sides: 110 = 10x

Divide both sides by 10: 11 = x

Take the derivative term by term.

d/dx(X - cosX)

= sin(X)

======

x/-5 + 8 = 11

To solve this:

Subtract 8: x/-5 = 3

Multply by -5: x = 3*-5

Work it out: 3*-5 = -15

x = -15
