Answer:

Infinity (the line would be vertical and thus the slope would be undefined)

Step-by-step explanation:

First, find the equation of the line connecting (-2, -2) and (-2, -3). Notice that x does not change here, while y does change. Thus, the line through these two points is a vertical one. Any line that is perpendicular to this vertical line x = -2 and situated between the given points will never touch the points.

The answer to this question is: One possible value for the slope of a line passing between the given points but not containing either one of them is "undefined." Actually, this is the ONLY possible value of the slope of this line thru (1,1) could have if you want a 100% guarantee that this line does not contain either (-2, -2) or (-2, -3).

The area of the rectangle as a single expression

Ne4ueva [31]

Answer: $A=15x^2+6x-48$

Step-by-step explanation:

The area of a rectangle can be calculated with this formula:

$A=l*w$

Where "l" is the length and "w" is the width.

You can identify from the figure that the length and the width of this rectangle are:

$length=3(x+2)\\width=5x-8$

Then, you need to substitute this lenght and this width into $A=l*w$ :

$A=3(x+2)(5x-8)$

Now, apply Distributive property:

$A=(3x+6)(5x-8)\\\\A=15x^2-24x+30x-48$

Finally, you need to add the like terms. Then, you get:

$A=15x^2+6x-48$

if there are 2040 seats in a section of a stadium, 20 seats in the first row, and 4 more seats in each row, how many rows are th

Lorico [155]

2040 = n/2(20+(n-1)4)

4080 = n(20+4n-4)

4080= 20n +4n^2 -4n

1020 = 4n + n^2

n^2 +4n -1020 =0

use common formula (can't write out so just look at answers. sorry)

which gives answers of n=-34 and n=30. since n can only be positive, n=30 so there are 30 rows. I liked that challenge
