Calculus

Get changed with the door closed. You went to bed clothed but woke up naked, what did you do about that? Did you ask your roommate if he had any idea of what happened. Where you drunk when you went to be. You must be sure before accusing someone of touching your balls at night. Lock your door when you go to bed at night. Set up a video camera in your room while your gone or home asleep. Sit down and have a talk with him before something happens that you will regret. This doesn't sound like a good home situation since you sound so very uncomfortable about it. You have options: move out or talk to him about it. Definitely lock your bedroom door.

X = 7.943282347242815

(x-3)(x-9) = 0

When they are added together, the sum is a monomial.

5x - 1 = 21 + 3x

Add '1' to both sides

5x = 22 + 3x

Subtract '3x' from both sides

2x = 22

Divide both sides by '2'

2x/2 = 22/2

x = 11

x=7 look at the bottom for the reason:

First, when a number and a variable are placed next to each other it means to multiply the 2. (example- what is 3x if x=7 ? Well, 3x7=21 so, 3x=21)

so, 5x + 2x + 3x + 10x = 140

20x = 140

40/20 = 7 so,

(5x7) + (2x7) + (3x7) + (10x7) = 140 so,

35 + 14 + 21 + 70 = 140

yes it does because the shorter the string is the faster it will go (:

x = -3/5 and y = -24/5

x-y = 120

x+y = 150

add equations:

2x = 270

x = 135

y = 15

2x + 3 = 9x

Subtract 2x from each side: 3 = 7x

Divide each side by 7: x = 3/7.

If you mean the straight line formula of: y = mx+b

Then: 2x-3y-6 = 0 or y = 2/3 x -2 so m=2/3 and b=-2

If you mean that 2x-3y = -6 , then y = 2/3 x + 2 so m=2/3 and b= +2

f(x) = x2

This is a function by the vertical line test because a vertical line drawn through this function will only intersect the function at one point

Do you mean?

int ex^2 dx

This is a integration by parts.

uv - int v du

u = x^2

du = 2X

dv = e

v = e

ex^2 - int e 2x

ex^2 - ex^2 + C

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

If X=0, then Y=1, therefore the point (0,1) is the y intercept.

If Y=0, then X=1, therefore the point (1,0) is the x intercept.

To Find: x^2 + x

Procedure:

Given: 3x - 1 = 11.

Solving, we have

3x - 1 + 1 = 11 +1

3 x = 12

x = 4

Therefore, x^2 + x = 4^2 + 4 = 16 + 4 = 20

===================

(x - (1.65831 + 0.5i))(x - (1.65831 - 0.5i))(x + (1.65831 - 0.5i))(x + (1.65831 + 0.5i)) where i is the square root of -1

I'm assuming you mean 2((-8)(3x)).

2(-24x)

-48x

x + y = -2

∴ y = -2 - x

xy = 2

∴ x(-2 - x) = 2

∴ -2x - x2 = 2

∴ x2 + 2x + 2 = 0

∴ x2 + 2x + 1 = -1

∴ (x + 1)2 = -1

∴ x + 1 = i

∴ x = i - 1

recall: y = - 2 - x

∴ y = - 2 - (i - 1)

∴ y = -2 - i + 1

∴ y = - i - 1

∴ x3 + y3 = (i - 1)3 + (- i - 1)3

= (i - 1)(i2 - 2i + 1) + (- i - 1)(i2 + 2i + 2)

= i3 - 2i2 + i - i2 + 2i - 1 - i3 - 2i2 - 2i - i2 - 2i - 2

= i3 - i3 - 2i2 - i2 - 2i2 - i2 + i + 2i - 2i - 2i - 1 - 2

= -6i2 - i - 3

= 3 - i

That is not solvable. It's like saying 7x2=2x2
