Answer:

\huge \boxed{ \boxed{  \tt - \frac{8}{11} }}

Step-by-step explanation:

<h3>to understand this</h3><h3>you need to know about:</h3>
  • linear equation
  • slope
  • PEMDAS
<h3>given:</h3>
  • points:(20,8),(9,16)
<h3>to find:</h3>
  • slope
<h3>tips and formulas:</h3>
  • m=\frac{y_2-y_1}{x_2-x_1}
<h3>let's solve:</h3>

let (20,8) and (9,16) be start and end points respectively

according to the question

  1. \sf\frac{8 - 16}{20 - 9}
  2. \sf substract : \\  \sf  \frac{ - 8}{11}

and we are done

Answer:

\huge  - \frac{8}{11}  \\

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} \\

From the question we have

m =  \frac{16 - 8}{9 - 20}  =  \frac{8}{ - 11}  =  -  \frac{8}{11}  \\

We have the final answer as

-  \frac{8}{11}  \\

Hope this helps you

Dima020 [189]

Answer:

0.43

Step-by-step explanation:

Yellow flowers are 43%.

White flowers are = (100% - 43% ) = 57%

Consider there are total 100 flowers in the garden , so yellow ones are 43 and white ones are 57

Probability of a bee landing on a yellow flower is 43 out of 100

= 43/ 100

=0.43

If y varies inversely as the square of x and y=4 when x=5, find y when x is 2
Len [333]

need to kind K

Y=k x 1/x^2 = k/x^2

Find K when y=4 & x=5

Y=k/x^2 =

4=k/5^2=

4=k/25

K=4*25 =100

When x = 2

Y=100/2^2

Y=100/4

Y=25
