The square root of 16 is 4.

The formula for slope is:  m  =  (y₂ - y₁) / (x₂ - x₁)

For this problem:     x₁ = -3     y₁ = 4     x₂ = 2     y₂ = -1

m  =  (y₂ - y₁) / (x₂ - x₁)     --->     m  =  (-1 - 4) / (2 - -3)  =  -5 / 5  =  -1

Problem  find the slope of:  2x + 3y  =  12

To find the slope of a line, you can place the equation into y-form, the slope will be the coefficient of x.

                                             2x + 3y  =  12

                                                      3y  =  -2x + 12

                                                        y  =  (-2/3)x + 4

The slope is  -2/3.

Problem:  find the x- and y-intercepts of  8x - 2y  =  24.

To find the x-intercept, substitute  0  for  y:  8x - 2(0)  =  24

                                                                               8x - 0  =  24

                                                                                    8x  =  24

                                                                                       x  =  3     --->     (3, 0)

To find the y-intercept, substitute  0  for  x:  8(0) - 2y  =  24

                                                                              0 - 2y  =  24

                                                                                  -2y  =  24

                                                                                     y  =  -12     --->     (0, -12)

3u - 7  =  -37

       3u  =  -30                         (Add 7 to both sides.)

         u  =  -10                         (Divide both sides by 3.)

-v + 5 + 6v  =  1 + 5v + 3

        5 + 5v  =  5v + 4         Now, subtract 5v from both sides:

                 5  =  4

Since this is impossible, the original expression really isn't an equation; therefore, there is no solution.

One standard deviation from the mean (both larger than and smaller than) holds approximatedly 68% of the population.

That means that 32% of the population is farther than one standard deviaiton from the mean, half of that (16%) is larger than one standard deviation above the mean and the other half (the other 16%) is smaller than one standard deviation below the mean.

Just use the slash button.

You just either type in you problem or press the buttons. Does that help?

ghost boo

aX + 7 =4X

aX - 4X = -7

X(a-4) =-7

X= -7/(a-4)  or 7/(4-a)

Is this an assignment or something you cooked in your head?

    last three digits of 1011*2012*3013*4014*5015*6016=  742,222,980,525,152,885,760                                                      

Huh. Cool. 

im doing math BAD

Well, technically it would be a multiple of itself, wouldn't it?

Multiply the exponents together and  cube the numerals to get

27x^6y^9

8.9*1.5 = 13.35 <---This is Kareem's pay

7.1*2 = 14.2 <---This is Cheryl's pay.

As we can see, 14.2>13.35, so Cheryl gets paid more for 1 hour of overtime.

Right now, you cannot simplify the problem further because there is nothing to simplify. The equation is x².

if 3t - 7 = 5t then 6t = what?

3t - 7  = 5t         subtract 3t from both sides

-7  = 2t           divide both sides by 2

-7/2  =  t   = -7/2

So...6t =   6(-7/2)  = -42 / 2    = -21

3t-7=5t

Subtract 3t from both sides

2t=-7

Divide by 2

t=-3.5

So now that we know what t is equal to, we can substitute it into the second equation.

6t

6(-3.5)

-21

So, 6t=-21
