The band played to  44,000  people total in the four cities.

They played to  12,450  people in Denver.

They played to  13,900  people in Las Vegas.

They played to  7,650  people in Reno.

How many people did they play to in Boston?

Let the number of people in Boston be  " x " .

We know the total is  44,000 , so...

12,450 + 13,900 + 7,650 + x  =  44,000      To solve for  x  , combine like terms on the left.

34,000 + x  =  44,000                                   Subtract  34,000  from both sides of the equation.

x  =  10,000

ah thanks that worked

3y + 6x  =  -24

Let's get this into slope-intercept form.  Add  6x  to both sides of the equation.

3y  =  6x - 24           Now divide through by  3 .

y  =  2x - 8

Now we can see that the slope is  2  and the y-intercept is  -8  .

To graph it, plot the y-intercept: (0, -8)

and from there, plot a point that is  2 units up and 1 unit right:  (1, -6)  ,

then connect these points with a straight line.  

Thank you for looking at this, now you should post some stuff! :P

y  =  3/4 x + 2

slope  =  3/4

y intercept  =  2

To graph it, plot the point  (0, 2) .

Then from there, go up 3 units and to the right 4 units, and plot a point here.. ( 4, 5 )

Then draw a straight line connecting these points.

To find the slope of a line, the equation is \(\frac{y_2-y_1}{x_2-x_1}\).

Plug in the point values.

\(\frac{-1+13}{6+6}\)

Simplify.

\(\frac{-1+13}{6+6}=\frac{12}{12}=1\)

So the slope is 1. Now use point-slope form, which is \(y-y_1=m(x-x_1)\).

Now, it doesn't matter which point you plug in. I'll use (-6,-13).

\(y+13=1(x+6)\)

Distribute the 1.

\(y+13=x+6\)

Subtract the 13 from both sides.

\(y=x-7\)

First let's find the slope.

slope  =  [-7 - -1] / [-7 - 14]  =  -6 / -21  =  2 / 7

Using the point  (14, -1)  and a slope of  2/7 , the equation in point-slope form is

y + 1  =  2/7 (x  - 14)

y  =  2/7x - (2/7)(14) - 1

y  =  2/7x - 4 - 1

y  =  2/7x - 5

Thank You! 

slope  =  [y₂ - y₁] / [x₂ - x₁]

Using the points  (-1, -3)  and  (x, y)  and a slope of  -3 , we have

-3  =  [y - -3] / [x - -1]

-3  =  [y + 3] / [x + 1]           To get this into slope-intercept form, multiply both sides by  x + 1 .

-3[ x + 1 ]  =  y + 3

-3x - 3  =  y + 3                   Subtract  3  from both sides of the equation.

-3x - 6  =  y

y  =  -3x - 6

Question: a.  In which quadrant does the ordered pair (6, -7) lie?       Quadrant:  _____________

b.  In which quadrant are all the X values negative and all the Y values negative?     Quadrant: ______________

Solution:

Here is a site to get you familiar with quadrants: https://en.wikipedia.org/wiki/Quadrant_(plane_geometry) 

But here is the answer, the pair (6,-7) is in the fourth quadrant

If both values or negative, there are in the third quadrant. 

Here is just something extra:

If the x value is positive and the y value is negative, it will be in the fourth quadrant

If the x value is positive and the y value is positive, it will be in the first quadrant

If the x value is negative and the y value is positive, it will be in the second quadrant

If the x value is negative and the y value is negative, it will be in the third quadrant

I hope this helped,

Find the ordered pair solution of y = 3/4x + 7  that corresponds to x=8

To find the ordered pair solution, you plug in the x value, which is 8

y = 3/4 * 8 + 7 

y = 6 + 7

y = 13

I hope this helped,

I am not familiar with LaTeX, but to create a scatterplot, you just plug to co-ordinates onto the plane without connecting the dots. 

For example, one point is 275, 76 another one is 310, 77

Make sure the x and y correspond to each other.

Hope this helped,

Find the slope of the line containing the points P1 and P2:  

P1(6, -4)     P2(4, -2)

To find the slope, it is the difference in y value and different in x value

-4 - ( -2) divided by 6 - 4

This is -2 over 2

which also is -1

I hope this helped,

Is (1, -3) a solution of y = -2x – 1 (show your work AND give me a yes or no answer)?

Yes, if you plug in 1 for x and -3 for y, the expression is true.

-3 = -2 * 1 - 1

Is true

I hope this helped! :)

Thanks!

Thanks Melody!

Solve for x:
(log(x))/(log(2)) + (log(3))/(log(2)) = 1 + (log(9))/(log(2))

Rewrite the left hand side by combining fractions. (log(x))/(log(2)) + (log(3))/(log(2)) = (log(x) + log(3))/(log(2)):
(log(x) + log(3))/(log(2)) = 1 + (log(9))/(log(2))

Multiply both sides by log(2):
log(x) + log(3) = log(2) + log(9)

Subtract log(3) from both sides:
log(x) = log(2) - log(3) + log(9)

log(2) - log(3) + log(9) = log(2) + log(1/3) + log(9) = log(2) + log(1/3) + log(9) = log((2 9)/3) = log(6):
log(x) = log(6)

Cancel logarithms by taking exp of both sides:
x = 6
