Find the slope of the line that passes through (10, 8) and (1, 9)?
sdas [7]

Answer:

The answer is

<h2>-  \frac{1}{9}</h2>

Step-by-step explanation:

The slope of a line given two points can be found by using the formula

m =  \frac{ y_2 - y _ 1}{x_ 2 - x_ 1}  \\

where

(x1 , y1) and (x2 , y2) are the points

From the question the points are

(10, 8) and (1, 9)

The slope is

m =  \frac{9 - 8}{1 - 10}  =  \frac{1}{ - 9}  \\  =  -  \frac{1}{9}

We have the final answer as

-  \frac{1}{9}  \\

Hope this helps you

Stacy wants to make 100 name tags with ribbons ATTACHED TO THEM. each name tag requires 5 centimeter of ribbon. SHE HAS 3.25 met
balandron [24]
Each meter has 100 centimeters. With just 1 meter, you can make 20 name tags with ribbons. So in order to make all of the name tags, you need 5 meters. 5 - 3.25 = 1.75. You need 1.75 more meters of ribbon to make all 100 of the name tags with ribbons.

There are 7 ushers and 11 technicians helping at the Harper Middle School fall play.
bearhunter [10]

Answer:

<h3>The ratio of technicians to all helpers  is 11 : 7, or \frac{11}{7} or 11 to 7.</h3>

Step-by-step explanation:

  • Given that there are 7 ushers and 11 technicians helping at the Harper Middle School fall play.
  • Let x be the number of ushers ( or helpers ).
  • Therefore x=7 helpers.
  • Let y be the number of technicians.
  • Therefore y=11 technicians.
<h3>To find the ratio of technicians to all helpers :</h3>

That is to find the ratio of y to x.

We can write the ratio of technicians to all ushers(helpers) as y : x

Which implies that 11 : 7,  (since y=11 and x=7)

Or \frac{11}{7} or 11 to 7

<h3>The ratio of technicians to all helpers  is 11 : 7, or \frac{11}{7} or 11 to 7</h3>

Cound someone please help me on this, I'm stuck. ​
Katyanochek1 [597]

Negative exponents work like this:

a^{-b}=\dfrac{1}{a^b}

So, in order to evaluate a negative exponent, you simply have to invert the base, and then raise to the positive equivalent of the exponent.

As an example, here are the first three exercises:

8^{-3}=\dfrac{1}{8^3}=\dfrac{1}{512}

(-4)^{-5}=\dfrac{1}{(-4)^5}=-\dfrac{1}{1024}

2k^{-4}=\dfrac{2}{k^4}

You can work out the rest applying this logic.
