M = (y2 - y1) / (x2 - x1)
Call (3,-4) one point
Call (-2,5) the second point.

m = (5- -4) / (-2 - 3)
m = 9/-5 = - 9 / 5

Sketch the graph of each line

adoni [48]

Answer:

(0,5) (1,0)

Step-by-step explanation:

Place your first dot on the 5 (0,5) of the y-axis (The one that is vertical) from there count down the line one value at a time until you have counted DOWN 5 times. Go to the right once and place another point there (1,0). Then draw a straight line that connects those two points.

The graph of this system of equations is used to solve 4x2-3+6=2x4-9x3+2x What represents the solution set?

Vilka [71]

ANSWER

x coordinates of the intersection points

EXPLANATION

The given system of equations is:

$y = 4 {x}^{2} - 3x + 6$

$y = 2 {x}^{4} - 9 {x}^{3} + 2x$

We want to use the graph of these functions to solve

$4 {x}^{2} - 3x + 6 = 2 {x}^{4} - 9 {x}^{3} + 2x$

The point of the intersection of the graph gives the solution to the simultaneous equation above.

Hence the x-coordinates of the intersection points gives the solution set of

$4 {x}^{2} - 3x + 6 = 2 {x}^{4} - 9 {x}^{3} + 2x$

The last choice is correct.

a rectangular lawn has an area of a^3 - 125. use the difference of cubes to find out the dimensions of the rectangle.

ANEK [815]

The area of a rectangle is the product of its dimensions

The dimensions of the rectangle are: $\mathbf{Length = a -5}$ and $\mathbf{Width = a^2 + 5a + 25}$

The area is given as:

$\mathbf{Area = a^3 - 125}$

Express 125 as 5^3

$\mathbf{Area = a^3 - 5^3}$

Apply difference of cubes

$\mathbf{Area = (a - 5)(a^2 + 5a + 5^2)}$

$\mathbf{Area = (a - 5)(a^2 + 5a + 25)}$

The area of a rectangle is:

$\mathbf{Area = Length \times Width}$

So, by comparison:

$\mathbf{Length = a -5}$

$\mathbf{Width = a^2 + 5a + 25}$
