Answer:

2/3

Step-by-step explanation:

To get the slope, you do (y2-y1)/(x2-x1).

You can also remember it as rise/run, as it is the change in y/change in x.

You can make either coordinate 1 or 2, just keep it consistent with the rest of the problem.

For this, I chose (-5, -7) to be 2, and (4, -1) to be 1.

Following the formula for slope, (y2-y1)/(x2-x1), you put the values in: (-7-{-1})/(-5-4).

-7 minus -1 is -6 and -5 minus 4 is -9.

Thus you get -6/-9. Don’t forget to simplify! A negaive divided by a negative is positive, and both 6 and 9 can be divided by 3. 3 goes into 6 TWO times and into 9 THREE times.

So, you get a positive fraction, 2/3.

Hope this helped.

Please help me as soon as posable!! In hurry!!(24 points)

The sequence is geometric, so

$a_n = r a_{n-1}$

for some constant r. From this rule, it follows that

$a_3 = r a_2 \implies 20 = 2r \implies r = 10$

and we can determine the first term to be

$a_2 = r a_1 \implies 2 = 10 a_1 \implies a_1 = \dfrac15$

Now, by substitution we have

$a_n = r a_{n-1} = r^2 a_{n-2} = r^3 a_{n-3} = \cdots$

and so on down to (D)

$a_n = r^{n-1} a_1 = 10^{n-1} \cdot \dfrac15$

(notice how the exponent on r and the subscript on a add up to n)

What is the equation of the line through (-6, -5) and (-4, -4)?

Norma-Jean [14]

Answer:

y = 1/2x -2

Step-by-step explanation:

The 2-point form of the equation for a line is useful for answering questions like this.

y = (y2 -y1)/(x2 -x1)(x -x1) +y1 . . equation of a line through (x1, y1) and (x2, y2)

Filling in the given points, the equation becomes ...

y = (-4 -(-5))/(-4 -(-6))/(x -(-6)) -5

y = 1/2(x +6) -5

y = 1/2x -2

Thomas buys a cardboard sheet that is 8 by 12 inches. Let x be the side length of each cutout. Create an equation for the volume

Alekssandra [29.7K]

Answer: Your equation would be y = x(12 - 2x)(8 - 2x).

The volume of a rectangular prism is V = LWH. The initial length and width are given as 12 and 8, however that makes the height 0.

If we cut out the corners, they would be the length of x. When we cut out the corners, we are subtract the length x from both ends of the length and width.

So now our measurements are:
Length: 12 - 2x
Side: 8 - 2x
Height: x

Multiply them altogether and you have your equation. Then, you can use your equation to find any measurements that you need.
