The x-intercept is the point where the graph crosses the x-axis and every point on the x-axis has a y-value of 0.

So put in 0 for y:  0 = 8 - 6x       --->   add 6x to both sides:  6x = 8     --->  divide by 6:  x = 1 1/3 

x-intercept = ( 1 1/3, 0)

The y-intercept is the point where the graph crosses the y-axis and every point on the y-axis has an x-value of 0.

So put in 0 for x:  y = 8 - 6(0)  --->  y = 8  --->  y-intercept = (0, 8)

Plot those two points and use them to draw your line.

The volume of a prism is length x width x height.

Does 'B' stand for the length of the base?

If so, the volume = 12 x 16 x 4  =  768.                    (if height = H = 16  and length = L = 4)

If 26 is the width, then the volume is 4 x 26 x 16  =  1664 

Multiply both sides by x:

(x)(2412/x) = (x)(.000362)        The x's on the left side cancel.

2412 = .000362x

Divide both sides by .000362

2412 / .000362  =  x

Divide this and you will have your answer.

Looking at just  -(-5 + x);

The negative sign in front of the parentheses change all the signs inside: so you end with +5 - x

x - (-5 + x) is the same as

x + -(-5 + x) which is

x + 5  - x

Find a common factor for all three factors: divide by 10:

  10:12:9

Since there is no other common factor; it is in lowest terms.

y = -5x + 5

It is a straight line that passes through the point (0,5) with a slope of -5.

y = mx + b is the slope-intercept form; for this problem, m = -5, b = 5.

Since the y-intercept is 5, start by placing a dot on the y-axis at 5.

Since the slope is -5, which is -5/1, to get another point, start at (0,5) and move to the right 1 and down 5; do this a couple more times, then draw the line.

A site that has the equation for this as well as a calculator is:

An average (mean) is found by taking the total and dividing by the number of items:

the average thickness of a sheet will be the answer to:  5 mm ÷ 40 sheets  =  

If you are asking for the solution of  x² + 2x + 1 = 0,

you can find the solution by graphing, by using the quadratic formula, by completing the square, and by factoring.

By factoring:  (x + 1)(x + 1)  =  0

To solve this:  set  x + 1  = 0    -->  x = -1

The other factor will again give you the solution:  x = -1.

                                            can +      jam = 400

                                            can + 1/2jam = 250

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

Subtract the columns:                      1/2jam = 150

Multiply by 2:                                       jam = 300

Since can + jam = 400 and jam = 300, can = 100
